0:00:02 > 0:00:05This programme some scenes which some viewers may find upsetting
0:00:29 > 0:00:31Ow!
0:00:58 > 0:01:01No, I'm really not happy with the arrangements for this evening.
0:01:03 > 0:01:04Couple of things.
0:01:04 > 0:01:06You say you can fit an extra ten people in the alcove
0:01:06 > 0:01:09by the window, but I've seen that alcove, and, with respect,
0:01:09 > 0:01:12a romantic meal for two would be a squeeze.
0:01:13 > 0:01:17It's my sister's baby shower and I need everything to be perfect.
0:01:17 > 0:01:19Listen, I'm coming over now.
0:01:21 > 0:01:23To show you how the seating can work.
0:01:27 > 0:01:30Honestly, it's no trouble. See you in a minute.
0:01:34 > 0:01:36SHE SIGHS

0:03:24 > 0:03:27DCI Andy Steemson. This is DS Karen Wretzky.
0:03:27 > 0:03:29Nikki Alexander, pathologist.
0:03:29 > 0:03:30Jack Hodgson, forensics.
0:03:30 > 0:03:32I know what you're thinking.
0:03:32 > 0:03:35It's only been 24 hours since Lucy disappeared,
0:03:35 > 0:03:37but there's something we're keeping under wraps.
0:03:37 > 0:03:42We got a one-second 999 call from her mobile at 9.23am.
0:03:42 > 0:03:45- Nothing audible.- Well, it should help with the location at least.
0:03:45 > 0:03:46Only picked up on the one mast.
0:03:46 > 0:03:48- So we can't triangulate.- No.
0:03:48 > 0:03:53Traces of what looks like blood and maybe fingerprints were found here -
0:03:53 > 0:03:55the samples are on their way to you.
0:03:55 > 0:03:58Of course, it's still possible that she walked off into the sunset,
0:03:58 > 0:04:01but I want to rule out that she was taken by force from this location.
0:04:01 > 0:04:04I also want to rule out that she's in this location.
0:04:04 > 0:04:05OK.
0:04:05 > 0:04:08Let me spell it out. A missing girl. A big search party.
0:04:08 > 0:04:09A media circus.
0:04:09 > 0:04:11Couple of days later, the body shows up in her home,
0:04:11 > 0:04:14in the attic or cellar, usually. It's been there all the time.
0:04:14 > 0:04:16That's not going to happen on my watch.
0:04:16 > 0:04:17You want a forensic guarantee
0:04:17 > 0:04:19there's not a dead body on the premises...
0:04:19 > 0:04:20basically?
0:04:20 > 0:04:22Basically, yeah.
0:04:22 > 0:04:24Fine. Then we'll need the run of the house.
0:04:26 > 0:04:27OK.
0:04:30 > 0:04:31He grows on you.
0:04:31 > 0:04:32I look forward to it.
0:04:36 > 0:04:37SHE SNIFFS
0:04:37 > 0:04:38Getting that burnt smell?
0:04:38 > 0:04:39Mm.
0:04:41 > 0:04:44This is a big place for a primary school teacher.
0:04:44 > 0:04:45Hm.
0:04:48 > 0:04:50I'm thinking family money.
0:04:56 > 0:04:59Got some bike treads here.
0:04:59 > 0:05:00No bike.
0:05:40 > 0:05:41Jack?
0:05:48 > 0:05:50What is that?
0:05:50 > 0:05:53I think it was...a cake.
0:05:53 > 0:05:56Who bakes a cake then disappears into the sunset?
0:06:03 > 0:06:04HE KNOCKS
0:06:15 > 0:06:17Haven't you got a rehearsal?
0:06:17 > 0:06:18No.
0:06:18 > 0:06:20Want me to run you in?
0:06:21 > 0:06:23No.
0:06:23 > 0:06:25Someone got a hangover by any chance?
0:06:26 > 0:06:28No.
0:06:28 > 0:06:31You've got two minutes. I'll make toast to go.
0:06:31 > 0:06:33Dad, I've got four lines.
0:06:33 > 0:06:38I don't want to spend my Sunday waiting to say them. Please!
0:06:38 > 0:06:39Mum won't be happy.
0:06:39 > 0:06:42Mum's not going to remember unless you tell her.
0:06:44 > 0:06:46Wow. They're searching the lane.
0:06:51 > 0:06:53Think they've found her?
0:06:53 > 0:06:57No idea. Tell you what, though, forget about the rehearsal.
0:06:57 > 0:06:59Dad, I can look after myself.
0:07:00 > 0:07:02Fair enough. Off you go, then.
0:07:55 > 0:07:57WHIMPERING
0:08:05 > 0:08:07WHIMPERING CONTINUES
0:08:22 > 0:08:27I found a cycling app on Lucy's laptop - it uploaded automatically
0:08:27 > 0:08:31and tells us she cycled 3.75 miles on the morning she vanished.
0:08:31 > 0:08:33What time was it activated?
0:08:33 > 0:08:35Um, 9.10.
0:08:35 > 0:08:37So, she triggered the program as she left her house...
0:08:37 > 0:08:39I'm ahead of you.
0:08:39 > 0:08:40Sorry.
0:08:40 > 0:08:41Traffic cams on the main road
0:08:41 > 0:08:45- were checked for the morning she went missing.- No sightings?- No.
0:08:45 > 0:08:50Leaving five surrounding lanes and a B-road.
0:09:05 > 0:09:08We've got something - bang on 3.75 miles from her house.
0:09:12 > 0:09:15WHIMPERING
0:09:29 > 0:09:32SHE GROANS AND CRIES
0:09:34 > 0:09:38'We believe Lucy left her home in Felking, Surrey, at around 9am
0:09:38 > 0:09:41'on Saturday morning and that she was riding
0:09:41 > 0:09:43'the bike in this photograph.
0:09:43 > 0:09:46'Did anyone see her in that area at that time?
0:09:46 > 0:09:51'Whoever's taken my sister, Lucy is a good person to her bones.
0:09:51 > 0:09:53'She'd help anyone in any situation,
0:09:53 > 0:09:58'and I want her back. I NEED her back.'
0:09:58 > 0:10:00MOBILE RINGS
0:10:03 > 0:10:04Hello.
0:10:07 > 0:10:09All right, I'll be there in 30 minutes.
0:10:32 > 0:10:35Hiya. Thomas Chamberlain.
0:10:35 > 0:10:38DS Steele. Maureen to my friends.
0:10:40 > 0:10:41Right.
0:10:44 > 0:10:48She's got track marks on both arms. Looks like a user.
0:10:48 > 0:10:50Just saying.
0:10:57 > 0:10:59Ah! I used to have one of them!
0:10:59 > 0:11:01I couldn't get those little tapes any more.
0:11:01 > 0:11:03Bloke on Tottenham Court Road still sells them.
0:11:03 > 0:11:06Yeah? When we're done, give me his details, would you?
0:11:06 > 0:11:07Gladly.
0:11:07 > 0:11:12Victim is female, no apparent ID, and is lying on her back.
0:11:12 > 0:11:14There's a single, penetrating wound to her chest,
0:11:14 > 0:11:18dusting of fine white powder to her tracksuit.
0:11:18 > 0:11:19Got to be coke, right?
0:11:19 > 0:11:23Well, yes...or talcum powder.
0:11:23 > 0:11:28Either way, she's not a primary school teacher, that's for sure.
0:11:28 > 0:11:32What is it with bank holiday weekends and girls going missing?
0:11:32 > 0:11:34I blame the tabloids myself.
0:11:34 > 0:11:37Check for a planar distribution of any injuries in case she fell
0:11:37 > 0:11:40or was thrown from the road above.
0:11:42 > 0:11:43Who called this in?
0:11:43 > 0:11:47Council engineer. Routine checks on the bridge struts.
0:11:47 > 0:11:51He was getting back into his van when, thank God, he found the body.
0:11:53 > 0:11:55If she was dumped from up there,
0:11:55 > 0:11:58killer's on camera one side of the bridge or the other.
0:11:58 > 0:12:02Well, I'll get on with the postmortem, if that suits.
0:12:02 > 0:12:04Before you do, do me a favour?
0:12:04 > 0:12:05What?
0:12:05 > 0:12:06Run her prints.
0:12:06 > 0:12:10If she hasn't got a record a mile long, I'll take it all back.
0:12:14 > 0:12:17Bike gets dragged under the car...
0:12:22 > 0:12:26Paint's a visual match to Lucy's bike -
0:12:26 > 0:12:28manufacturer will confirm that.
0:12:28 > 0:12:31Now we know the road she took, we can do targeted house-to-house...
0:12:41 > 0:12:43Strand of hair!
0:12:52 > 0:12:55Must've hit her at speed to send her off the road at this height.
0:12:55 > 0:12:57Brake marks on the asphalt back that up.
0:12:57 > 0:12:59Bastard.
0:12:59 > 0:13:00Tread prints?
0:13:00 > 0:13:01Jack?
0:13:01 > 0:13:05We'll see, but when wheels lock up, all you tend to get is burnt rubber.
0:13:11 > 0:13:15We need to search these woods now in case she came round and wandered off.
0:13:17 > 0:13:18What, you're not hopeful?
0:13:18 > 0:13:20That velocity and impact - no.
0:13:20 > 0:13:22Given that her bike and phone are missing,
0:13:22 > 0:13:25it's more likely the assailant removed her body from the scene.
0:13:57 > 0:13:59You'll be pleased to know you were entirely correct.
0:13:59 > 0:14:01About our victim?
0:14:01 > 0:14:04Mm-hm. Tina Lunt, 32.
0:14:04 > 0:14:07Long record for theft and possession - coke and cannabis -
0:14:07 > 0:14:10nothing for a couple of years, though.
0:14:10 > 0:14:13She's listed as divorced, ten-year-old son.
0:14:16 > 0:14:19Jack, I need you to check out the white powder on this tracksuit.
0:14:19 > 0:14:21Sure. Just leave it on my desk.
0:14:22 > 0:14:25Right. When do you think you might get round to it?
0:14:25 > 0:14:29Er, this afternoon, the earliest. Might need a gentle nudge.
0:14:29 > 0:14:30Count on it.
0:14:32 > 0:14:37Although both arms bear scars suggestive of needle-use,
0:14:37 > 0:14:42the marks are old - months, possibly years -
0:14:42 > 0:14:45no evidence of recent activity.
0:14:45 > 0:14:48Maybe she was smoking it?
0:14:48 > 0:14:50Yeah, why don't we see what tox says?
0:14:52 > 0:14:56There's some kind of metal object embedded in her chest.
0:14:56 > 0:14:58Can you see?
0:14:58 > 0:14:59Oh.
0:14:59 > 0:15:03Clean, neat entry wound. Right.
0:15:07 > 0:15:09Let's have a look at it.
0:15:18 > 0:15:20My God.
0:15:24 > 0:15:26It's a fork screwdriver.
0:15:27 > 0:15:31The tip of the screwdriver has been bent at a 45-degree angle.
0:15:31 > 0:15:33The metal is discoloured with a mottled sheen,
0:15:33 > 0:15:35suggesting it's been heated and recast.
0:15:35 > 0:15:39There's also, can you see, crisscross markings on the shaft,
0:15:39 > 0:15:41possibly from being clamped in a vice.
0:15:44 > 0:15:46Wow.
0:15:47 > 0:15:50You see these plastic flakes in the wound?
0:15:50 > 0:15:54- Yeah.- She was stabbed with such force, the handle broke clean off.
0:15:54 > 0:15:55That's unusual?
0:15:55 > 0:15:58Very. Tool handles are made with cellulose acetate -
0:15:58 > 0:16:00noted for its extreme durability.
0:16:00 > 0:16:04All of which suggests it was done deliberately.
0:16:04 > 0:16:06And that couldn't have bent when it struck her sternum?
0:16:06 > 0:16:07No.
0:16:09 > 0:16:13So, what kind of person needs to modify the end of a screwdriver?
0:16:15 > 0:16:19Did you see or hear anything unusual yesterday morning?
0:16:19 > 0:16:21Car alarm.
0:16:21 > 0:16:24That's right. My car alarm went off.
0:16:24 > 0:16:27I didn't hear it because our bedroom faces the back.
0:16:27 > 0:16:28And you sleep like a donkey.
0:16:28 > 0:16:30That, too. Yep.
0:16:30 > 0:16:32It woke you up, though?
0:16:32 > 0:16:34I went out and checked on the car.
0:16:34 > 0:16:37Nothing suspicious - no indication why it'd gone off.
0:16:37 > 0:16:39Has that happened before?
0:16:39 > 0:16:41Once or twice. Not lately.
0:16:41 > 0:16:43I just turned it off.
0:16:45 > 0:16:48What time was that? When you were out on the drive?
0:16:48 > 0:16:50It was about nine, I think.
0:16:50 > 0:16:52Maybe a bit after.
0:16:52 > 0:16:55Mr Timpson, that's exactly when we think Lucy cycled past on the lane.
0:16:55 > 0:16:57You're sure you didn't see her?
0:16:57 > 0:16:58Positive.
0:16:58 > 0:16:59What about a vehicle?
0:17:00 > 0:17:05I'm sorry. I just shut off the alarm, went back to bed.
0:17:05 > 0:17:07It was my day off.
0:17:07 > 0:17:08What do you do?
0:17:08 > 0:17:10I'm a GP.
0:17:11 > 0:17:12You're married?
0:17:12 > 0:17:14My wife's in her study if you need to speak to her.
0:17:14 > 0:17:16Was she around Saturday morning?
0:17:16 > 0:17:18She was asleep next to me.
0:17:19 > 0:17:23I saw someone this morning in the lane...
0:17:23 > 0:17:24big guy in his 30s.
0:17:24 > 0:17:25He was weird.
0:17:25 > 0:17:29He pulled up across the road, just staring at the house.
0:17:29 > 0:17:31When he saw me, he drove off.
0:17:31 > 0:17:33Do you remember what kind of car? The colour?
0:17:33 > 0:17:38Golf... Fiesta? That kind of thing. Black or navy.
0:17:38 > 0:17:41You definitely didn't recognise him?
0:17:41 > 0:17:42Why?
0:17:42 > 0:17:44Guess I'm just wondering
0:17:44 > 0:17:46whether he was watching the house or watching you.
0:17:50 > 0:17:53Good, we got the CT scan back.
0:17:53 > 0:17:58Seems the shaft made an upward, diagonally-oriented chest wound,
0:17:58 > 0:18:02penetrated the pleural cavity here and was cause of death.
0:18:08 > 0:18:10I don't get it.
0:18:10 > 0:18:15It must've gone through the flesh with massive force not to tear the surrounding skin...
0:18:15 > 0:18:19See these fragments of bone? Smashed right through her sternum.
0:18:19 > 0:18:22So, what, we're looking for a body-builder? A giant?
0:18:22 > 0:18:26Maybe to the former, no to the latter.
0:18:27 > 0:18:30If you were going to stab me with a screwdriver, DS Steele,
0:18:30 > 0:18:32how would you do it?
0:18:32 > 0:18:34Go on, show me.
0:18:34 > 0:18:37Yeah, classic stabbing movement. Downward arc.
0:18:37 > 0:18:39But a downward arc yields a downward wound tract.
0:18:39 > 0:18:41What, and we've got the opposite?
0:18:41 > 0:18:45Yeah. Upward trajectory - so either our killer is three foot tall
0:18:45 > 0:18:48or they stabbed her from some kind of lowered position,
0:18:48 > 0:18:50but that would've resulted in a far messier entry wound.
0:18:53 > 0:18:54Clarissa?
0:18:54 > 0:18:57Tox is back on Tina Lunt - clean for drugs and alcohol.
0:19:00 > 0:19:03Fancy a trip to her flat in Hounslow?
0:19:10 > 0:19:11SHE GROANS
0:19:18 > 0:19:20SHE CRIES OUT
0:19:22 > 0:19:24Oh. OK. Thanks.
0:19:25 > 0:19:26Bad news?
0:19:26 > 0:19:28No traffic cams on the bridge.
0:19:28 > 0:19:32Nearest one is the other side of a six-outlet roundabout.
0:19:32 > 0:19:35Oh, so, no way of telling which vehicles went over the bridge?
0:19:35 > 0:19:38And they whine about us being the CCTV capital of the world...
0:19:43 > 0:19:46Oh, hang on. We should get uniforms to sweep, shouldn't we?
0:19:46 > 0:19:48Oh, sod that.
0:19:48 > 0:19:49Hello?
0:19:51 > 0:19:52Hello?
0:19:54 > 0:19:55Oh...
0:20:19 > 0:20:20Jesus! You all right?
0:20:20 > 0:20:21Yes. Go on!
0:21:00 > 0:21:02CAR DOOR CLOSES
0:21:14 > 0:21:15Oh!
0:21:16 > 0:21:18Did you get his registration number?
0:21:21 > 0:21:24If you remember anything else, please call us.
0:21:24 > 0:21:25Thank you.
0:21:30 > 0:21:31FOOTSTEPS
0:21:33 > 0:21:35That was the police.
0:21:35 > 0:21:36I heard.
0:21:40 > 0:21:43Why did you have to tell them about the bloody car alarm?
0:21:52 > 0:21:56When you turned the alarm off, was Alec's Land Rover outside?
0:21:56 > 0:21:58You're getting in a state about nothing.
0:21:58 > 0:22:00Was it parked outside?
0:22:00 > 0:22:01No, I don't think so.
0:22:01 > 0:22:04But that doesn't mean much.
0:22:04 > 0:22:06He always parks beside the guesthouse,
0:22:06 > 0:22:08and you can't see back there from the drive.
0:22:14 > 0:22:16SHE GROANS
0:22:42 > 0:22:44Find anything?
0:22:44 > 0:22:47Five empty beer bottles. No alcohol in Tina's blood, remember.
0:22:47 > 0:22:48Could be our runner's?
0:22:48 > 0:22:53Yeah. What do you think? Came back here to clean up?
0:22:53 > 0:22:55No sign of a mobile?
0:22:55 > 0:22:56No.
0:23:14 > 0:23:17Empty, but still a mess. Bit like my place.
0:23:37 > 0:23:38DS Steele.
0:23:44 > 0:23:49Same crisscross markings as the one I extracted from Tina's chest.
0:23:49 > 0:23:51What was she into?
0:23:51 > 0:23:54Something tells me our runner might've had an inkling.
0:23:54 > 0:23:56All right. Don't rub it in.
0:24:08 > 0:24:09Christ.
0:24:09 > 0:24:12It's probably been like this for days.
0:24:22 > 0:24:23Sell-by date tomorrow.
0:24:23 > 0:24:24So?
0:24:26 > 0:24:28So, it means he could've been here on Friday night.
0:24:28 > 0:24:29Ellie...
0:24:29 > 0:24:32Like you said, we wouldn't know.
0:24:34 > 0:24:37OK, so he was here on Friday night? So what?
0:24:39 > 0:24:41What are you worried about?
0:24:41 > 0:24:42I don't know.
0:24:44 > 0:24:47You can't think Alec's got anything to do with this girl?
0:24:47 > 0:24:49No!
0:24:49 > 0:24:51No, of course not.
0:24:51 > 0:24:52So...?
0:24:52 > 0:24:55It doesn't matter what I think.
0:24:55 > 0:24:58If they find out about Alec, they'll...
0:24:58 > 0:25:01They'll be all over him like a rash.
0:25:03 > 0:25:07He won't survive it, not again.
0:25:10 > 0:25:13SHE GRUNTS
0:25:42 > 0:25:44Isn't this a bit excessive?
0:25:45 > 0:25:46I hope so.
0:25:48 > 0:25:51What's going on?
0:25:51 > 0:25:53Just having a bit of a clear-out.
0:25:53 > 0:25:56That's Alec's coat. Why are you chucking it out?
0:25:56 > 0:25:57It's falling apart.
0:25:57 > 0:25:58It's his coat.
0:25:58 > 0:26:01Jessica, please, what do you want?
0:26:13 > 0:26:15I'm sure your brother can look after himself.
0:26:15 > 0:26:17Can he?
0:26:17 > 0:26:18I'm not so sure.
0:26:46 > 0:26:48Is that dope?
0:26:48 > 0:26:51I thought the first rule of Alec using the guesthouse was no guests,
0:26:51 > 0:26:52female or otherwise?
0:26:53 > 0:26:55Jessica.
0:26:55 > 0:26:56What?
0:26:56 > 0:26:58How do you know?
0:26:58 > 0:27:01It's my lipstick. She's always borrowing it.
0:27:01 > 0:27:04I'll talk to Jess. I'm better at that stuff than you.
0:27:05 > 0:27:07It's not her I'm angry with.
0:27:16 > 0:27:18RINGING
0:27:20 > 0:27:22RINGING
0:27:28 > 0:27:32RINGING CONTINUES
0:27:33 > 0:27:36- 'Please leave a message after the tone.' - BEEP
0:27:36 > 0:27:41Alec, listen, it's very important that you don't use the guesthouse for a bit.
0:27:41 > 0:27:43Don't even come to the house.
0:27:43 > 0:27:46Um... I'll explain when I speak to you.
0:28:01 > 0:28:03Jessica?
0:28:03 > 0:28:06Jessica, are you OK?
0:28:06 > 0:28:08Yeah. Sorry. I'll turn around.
0:28:08 > 0:28:09OK.
0:28:09 > 0:28:11RINGING
0:28:11 > 0:28:13Just finishing up here, sir. Yep...
0:28:17 > 0:28:19HOOTS HORN
0:28:19 > 0:28:20Hey! Watch out!
0:28:30 > 0:28:32Are you all right?
0:28:32 > 0:28:34No, I'm fine. Yep, sorry.
0:29:39 > 0:29:42ENGINE
0:29:59 > 0:30:00DOOR CLOSES
0:30:16 > 0:30:17DOOR CREAKS
0:30:25 > 0:30:26Ah!
0:30:32 > 0:30:34BREATHES HEAVILY
0:30:53 > 0:30:55CLATTERING
0:33:34 > 0:33:35You didn't call me back.
0:33:49 > 0:33:52Want a drink or something?
0:33:52 > 0:33:53No, no, I'm fine.
0:34:00 > 0:34:02You got my message?
0:34:02 > 0:34:03Yes.
0:34:04 > 0:34:07Some girl has gone missing?
0:34:07 > 0:34:12Just down the road from us. All things considered, I...
0:34:12 > 0:34:14I think it would be best if you...
0:34:14 > 0:34:16What? If I... If I stayed away?
0:34:17 > 0:34:21Of course. Fine. I'll stay away.
0:34:21 > 0:34:22OK.
0:34:28 > 0:34:31Last week, which night did you stay at the guesthouse?
0:34:31 > 0:34:38Um... Tuesday, Wednesday I was panelling at the golf club...
0:34:40 > 0:34:42..er...Thursday night.
0:34:42 > 0:34:43Not Friday night?
0:34:43 > 0:34:44Why are you asking?
0:34:44 > 0:34:47The girl went missing on Saturday morning.
0:34:47 > 0:34:49If they found out that you were in the area...
0:34:52 > 0:34:55..we all know how quickly they jump to conclusions.
0:34:55 > 0:34:56What about you, Ellie?
0:34:56 > 0:34:58Are you jumping to any conclusions?
0:34:58 > 0:35:00That is not fair, Alec.
0:35:00 > 0:35:02But it's true.
0:35:02 > 0:35:05Back then, do you think that I would've lied for you?
0:35:05 > 0:35:09Do you think I would have given you an alibi if I'd had any doubts whatsoever?
0:35:12 > 0:35:13I'm sorry.
0:36:18 > 0:36:19Thanks.
0:36:40 > 0:36:43Lucy has a swallow tattoo on her left wrist.
0:36:47 > 0:36:51No visible decomposition. She can't have been in the water long.
0:36:51 > 0:36:52You think he dumped her today?
0:36:52 > 0:36:54I'd say in the last two to four hours.
0:36:54 > 0:36:55He's confident.
0:37:02 > 0:37:05I swabbed the tool kit - multiple prints and DNA samples,
0:37:05 > 0:37:06mostly belonging to Tina herself.
0:37:06 > 0:37:08What about the lager bottles?
0:37:08 > 0:37:14Well, again, multiple prints and DNA, but only one overlapping with the samples from the tool kit.
0:37:14 > 0:37:18Belonging to a Wesley Beale.
0:37:18 > 0:37:21His CV reads like a criminal decathlon.
0:37:21 > 0:37:23That's him. That's the man I chased.
0:37:23 > 0:37:24You chased someone?
0:37:24 > 0:37:26Yeah.
0:37:26 > 0:37:27Is there CCTV?
0:37:27 > 0:37:31What have we got - blackmail, housebreaking, drug dealing...
0:37:31 > 0:37:33And that's just the shit we nicked him for.
0:37:33 > 0:37:35- Current address?- Er, no,
0:37:35 > 0:37:39but last time he was arrested, he gave Maconi's car mechanics
0:37:39 > 0:37:41in Hounslow as his place of employment.
0:37:41 > 0:37:45Owner Marc Maconi nicked but not charged back in '04
0:37:45 > 0:37:48for stealing stereos and airbags.
0:37:48 > 0:37:52Off-limits, I'm afraid - as he didn't do it.
0:37:54 > 0:37:56Weasley Beale worked here, right?
0:37:56 > 0:37:59About two years ago. So what?
0:37:59 > 0:38:00When did you last see him?
0:38:02 > 0:38:04We didn't stay in touch.
0:38:04 > 0:38:07Aww, did you and Wesley have a falling out(?)
0:38:07 > 0:38:11After he got busted, you lot turned this place over for days.
0:38:11 > 0:38:13And that was a cause for concern, was it?
0:38:13 > 0:38:17Loss of trade was my concern, nothing else.
0:38:17 > 0:38:21- So, do you know where we might find Wesley?- No.
0:39:17 > 0:39:20Oi! What, you lost or something?
0:39:22 > 0:39:24Need a warrant to be nosing about in here.
0:39:24 > 0:39:25You got one?
0:39:25 > 0:39:29- No.- Well, it's trespassing, then, innit?
0:39:29 > 0:39:31And if you're trespassing...
0:39:31 > 0:39:33If I'm trespassing, what?
0:39:33 > 0:39:35Then the law's on my side.
0:39:35 > 0:39:37Wouldn't bet on it, mate.
0:39:40 > 0:39:41Let's go.
0:39:46 > 0:39:48What was that about?
0:39:48 > 0:39:49You get anything on Beale?
0:39:49 > 0:39:51Nope.
0:39:51 > 0:39:54RINGING
0:39:54 > 0:39:56Thomas.
0:39:56 > 0:40:00Jack. Have you checked out the white powder on that tracksuit?
0:40:00 > 0:40:03Sorry, haven't got to it yet.
0:40:03 > 0:40:04Right.
0:40:04 > 0:40:06I did say you might need to nudge me.
0:40:06 > 0:40:09Yeah, well, consider this a nudge. First and last.
0:40:12 > 0:40:13He hung up on me!
0:40:23 > 0:40:26There's a deep ligature wound to the throat.
0:40:27 > 0:40:31Skin damage has released a serum that's dried out in patches in a parchment effect -
0:40:31 > 0:40:35that could be consistent with death by strangulation.
0:40:35 > 0:40:39Left earlobe's torn - a wound often caused by a snagged earring.
0:40:39 > 0:40:41Could've happened when she came off the bike?
0:40:41 > 0:40:47Hm, scabbing over the wound suggests it was sustained at least a week ago - maybe longer.
0:40:47 > 0:40:49We'll ask her sister about it.
0:40:58 > 0:41:00A clump of her hair's been cut off.
0:41:01 > 0:41:03Trophy?
0:41:37 > 0:41:43The lack of lividity and general decomposition suggests she died between 12 and 24 hours ago.
0:41:45 > 0:41:47So, where was he keeping her since Saturday morning?
0:41:52 > 0:41:57Two distinct injuries to the skull. One, here -
0:41:57 > 0:41:58to the side...
0:42:02 > 0:42:08..where we can see bark embedded in the flesh.
0:42:09 > 0:42:12This one's partially healed.
0:42:12 > 0:42:16Well, that makes sense - we know she didn't die when he ran her down.
0:42:17 > 0:42:20Second head injury...
0:42:21 > 0:42:24..right on the back of the skull.
0:42:24 > 0:42:25Unhealed.
0:42:29 > 0:42:35And there's what look like cement chips in this wound.
0:42:35 > 0:42:38So, he hits her head against a wall? The floor?
0:42:38 > 0:42:43And with massive force - it staved in the rear of her skull.
0:42:43 > 0:42:45Death would've been almost instantaneous.
0:42:45 > 0:42:49So, what killed her? The ligature wound or the smashed skull?
0:42:49 > 0:42:51I don't know.
0:42:52 > 0:42:53Yet.
0:43:15 > 0:43:19So, given the victim's criminal history, I thought I'd start
0:43:19 > 0:43:21with a wet chemistry test to see if the powder was cocaine.
0:43:21 > 0:43:22- Negative?- Negative.
0:43:22 > 0:43:25So, I spun it down in this guy, checked it under the scope.
0:43:25 > 0:43:26It's cornstarch.
0:43:26 > 0:43:27Cornstarch?
0:43:27 > 0:43:29Which is found pretty much everywhere.
0:43:29 > 0:43:32But the dispersal of the powder - not just all over the clothes
0:43:32 > 0:43:35but embedded in the fabric - prompted a best guess.
0:43:36 > 0:43:39I think your victim was in a car where the air bag exploded.
0:43:41 > 0:43:43Maconi has form for stolen airbags.
0:43:43 > 0:43:44That's leverage.
0:43:44 > 0:43:46He tells us where Beale is
0:43:46 > 0:43:49or we take our time turning his garage over.
0:43:49 > 0:43:51Yeah, starting with that machine room upstairs.
0:43:51 > 0:43:54Marks on his vice match marks on Tina's screwdrivers.
0:43:54 > 0:43:56My guess is she's into air-bag theft
0:43:56 > 0:43:58and bent the tips to prise them out...
0:44:00 > 0:44:02Always happy to help!
0:44:12 > 0:44:15There's no bruising in the musculature of the neck.
0:44:15 > 0:44:17OK.
0:44:17 > 0:44:20The hyoid bone is fractured, but there's no bleeding.
0:44:20 > 0:44:21And that tells you what?
0:44:21 > 0:44:24That the ligature wound was inflicted after death.
0:44:24 > 0:44:25The skull fracture killed her?
0:44:25 > 0:44:27Making strangulation redundant.
0:44:29 > 0:44:32Maybe not. Maybe that was the main event.
0:44:34 > 0:44:37I worked on a serial case when I was a DC.
0:44:37 > 0:44:39The guy's thing was posthumous mutilation.
0:44:39 > 0:44:44He killed his victims with a hammer and then had his fun.
0:44:45 > 0:44:48He's confident, careful and forensically aware.
0:44:48 > 0:44:50I'd be very surprised if he hadn't killed before.
0:44:55 > 0:44:59I might be able to help with a timeline on the injury to Lucy's ear.
0:44:59 > 0:45:00How?
0:45:00 > 0:45:04A recent selfie. Uploaded automatically to her cloud.
0:45:06 > 0:45:08Yeah.
0:45:08 > 0:45:13Note...there, the lovely - but snaggable - earrings.
0:45:13 > 0:45:16Photo was taken nine days ago.
0:45:16 > 0:45:20You thought the ear injury was over a week old.
0:45:20 > 0:45:22Could have just been a sartorial mishap.
0:45:22 > 0:45:24But it would be nice to be sure.
0:45:24 > 0:45:29If you'd nothing to hide, Mr Beale, why did you run?
0:45:29 > 0:45:31You never said you was police!
0:45:31 > 0:45:33You never gave us much chance.
0:45:33 > 0:45:36I didn't know who you were.
0:45:36 > 0:45:39Tina had a lot of dodgy mates, God rest her soul.
0:45:41 > 0:45:43God rest her soul.
0:45:46 > 0:45:50Dumped in wasteland. Talk about insult to injury.
0:45:50 > 0:45:52That's where you found her?
0:45:52 > 0:45:53Where is this place?
0:45:53 > 0:45:55I ask the questions, Wesley.
0:45:56 > 0:45:59Your finger prints are all over these screwdrivers.
0:45:59 > 0:46:02Want to tell me what the angled tips are about?
0:46:03 > 0:46:05No idea.
0:46:05 > 0:46:10I think they make it easier to prise the airbags out without them deploying.
0:46:10 > 0:46:15That's your line of work, isn't it? Airbags. One of them, anyway.
0:46:16 > 0:46:19Well, what happened? You and Tina have a falling out?
0:46:19 > 0:46:21She didn't want to do it any more?
0:46:21 > 0:46:23And you found another use for your screwdrivers?
0:46:23 > 0:46:26KNOCKING
0:46:26 > 0:46:28You got a minute?
0:46:28 > 0:46:31We swept his car and his flat.
0:46:31 > 0:46:33There's no sign of any air-bag residue.
0:46:33 > 0:46:34Shit!
0:46:37 > 0:46:40You said whoever killed Tina had superhuman strength?
0:46:40 > 0:46:42Well, I didn't use those precise words.
0:46:42 > 0:46:46Oh, whatever. He's a big bastard, isn't he?
0:46:47 > 0:46:49I haven't got a thing to hold him on.
0:46:54 > 0:46:56I'm sorry to put you through this, Alice.
0:46:56 > 0:46:58It's OK.
0:47:26 > 0:47:27Look like them?
0:47:29 > 0:47:30They were Mum's.
0:47:43 > 0:47:45Is that your husband outside?
0:47:45 > 0:47:48Yes. He's waiting to take me home.
0:47:50 > 0:47:52So, Lucy lived here all by herself?
0:47:52 > 0:47:55You can ask.
0:47:55 > 0:47:58Why didn't big sister get the big house?
0:47:59 > 0:48:01My parents cut me out of their will.
0:48:01 > 0:48:06They were worried whatever money they left me would've gone straight up my nose.
0:48:08 > 0:48:10Back then, they were probably right.
0:48:15 > 0:48:18The blood found here matched Lucy's DNA.
0:48:18 > 0:48:20Lucy told her sister that she caught her earring
0:48:20 > 0:48:22on a bush getting out of a taxi.
0:48:23 > 0:48:26But even if the taxi didn't drop her at the front door...
0:48:28 > 0:48:31Seems a stretch she'd stumble into the bushes.
0:48:33 > 0:48:35So, why lie about it?
0:48:37 > 0:48:42We'll swab for DNA, but there's an outside chance you won't have to wait that long.
0:48:42 > 0:48:43Why not?
0:48:43 > 0:48:45Partial print in the blood.
0:48:46 > 0:48:51Probably Lucy's, but it's on the large side.
0:49:12 > 0:49:13Not Lucy's.
0:49:13 > 0:49:15Christ! That's Alice's husband.
0:49:17 > 0:49:21Lucy's blood. Your fingerprint.
0:49:21 > 0:49:24With your record, I'm thinking you wanted drug money.
0:49:25 > 0:49:28When Alice's parents cut her out of their will,
0:49:28 > 0:49:31Lucy promised that she'd get her share.
0:49:31 > 0:49:32She reneged?
0:49:32 > 0:49:36They died within a month of each other two years ago. We never saw a penny.
0:49:36 > 0:49:38And Alice with a baby on the way.
0:49:38 > 0:49:41Exactly, and we've been clean for more than a year.
0:49:41 > 0:49:43Both of us.
0:49:43 > 0:49:44So, you confronted her?
0:49:50 > 0:49:51What do you want, Jasper?
0:49:51 > 0:49:53Can I come in a second, please?
0:49:53 > 0:49:55My financial affairs are between me and my sister.
0:49:55 > 0:49:57Well, your sister's carrying my child.
0:49:57 > 0:50:00If she wants to play happy families with a junkie, that's her prerogative.
0:50:00 > 0:50:01Oh!
0:50:09 > 0:50:12If... If she'd have just talked to me in a civilised way...
0:50:14 > 0:50:16Where were you Saturday morning?
0:50:16 > 0:50:17At home.
0:50:17 > 0:50:18With Alice?
0:50:18 > 0:50:22No, she had an antenatal class.
0:50:22 > 0:50:26You must've been crapping yourself she'd tell Alice what you'd done.
0:50:26 > 0:50:29That was motive enough to shut Lucy up, and if it wasn't?
0:50:29 > 0:50:33Well, there's the massive sweetener that with her gone, Alice would inherit
0:50:33 > 0:50:36- and you'd be moved into that big house before the baby was born. - That is NOT what happened.
0:50:36 > 0:50:38- Prove it.- No. That's your job.
0:50:50 > 0:50:54Alice. There's something you need to know about Jasper.
0:50:56 > 0:50:59Tell me you've got something, please?
0:50:59 > 0:51:03Jasper's car tyres match the width of the brake marks on the lane.
0:51:03 > 0:51:08We can compare rubber samples all day long, but it's not DNA.
0:51:11 > 0:51:14What does he do? Jasper?
0:51:14 > 0:51:15He taught creative writing.
0:51:15 > 0:51:16Interesting.
0:51:16 > 0:51:17Why?
0:51:17 > 0:51:19Well, if you're right about him,
0:51:19 > 0:51:22we could be looking at some very creative staging.
0:51:22 > 0:51:25He runs Lucy down but she doesn't die.
0:51:25 > 0:51:28He doesn't have the stomach to kill her with his bare hands,
0:51:28 > 0:51:31so he keeps her somewhere while he summons the courage.
0:51:31 > 0:51:32When it comes to disposal,
0:51:32 > 0:51:35he does everything he can to suggest a psychosexual motive.
0:51:35 > 0:51:39The severed hair, the body left naked, the posthumous strangulation.
0:51:39 > 0:51:41All misdirection.
0:51:41 > 0:51:45He is arrogant enough to try that on, but I need more than theories.
0:51:45 > 0:51:48If it wasn't for the water we would know more about where he kept her.
0:51:48 > 0:51:51There is one place that we haven't looked. Her turbinates.
0:51:51 > 0:51:53The cavities in her nose.
0:51:53 > 0:51:58Not usually examined at PM, but they can trap material not detectable elsewhere on the body.
0:53:17 > 0:53:18Listen, please...
0:53:18 > 0:53:20There's nothing I want to hear you say.
0:53:20 > 0:53:23She was never going to give us the money. Never.
0:53:23 > 0:53:25I-I was thinking of our baby!
0:53:25 > 0:53:26My baby!
0:53:29 > 0:53:32I ran the washings from Lucy Chatham's turbinates -
0:53:32 > 0:53:35nothing out of the ordinary except trace levels of cornstarch.
0:53:35 > 0:53:37Cornstarch?
0:53:37 > 0:53:38What?
0:53:42 > 0:53:45Thomas! You're going to want to see this.
0:53:46 > 0:53:49- What is it? - What's this sample from?
0:53:49 > 0:53:52This is cornstarch found on their victim, Tina Lunt.
0:53:52 > 0:53:55- As you know, I think it's from an air bag.- Yeah, and...?
0:53:55 > 0:53:59And Clarissa's just retrieved cornstarch powder from Lucy Chatham's turbinates.
0:53:59 > 0:54:01The samples are identical.
0:54:01 > 0:54:02Hang on, hang on...
0:54:02 > 0:54:03If they are from airbags,
0:54:03 > 0:54:06then surely hundreds are deployed every day, yeah?
0:54:06 > 0:54:08But the majority have silicate filling, not cornstarch.
0:54:08 > 0:54:11What are the chances of two women being murdered within a day
0:54:11 > 0:54:15of each other coming into contact with the same cornstarch powder?
0:54:15 > 0:54:17Bloody slim, I'd say.
0:54:17 > 0:54:18We're working the same case.
0:54:18 > 0:54:21Do you have a suspect in your case?
0:54:21 > 0:54:23Listen... I'm not stupid.
0:54:24 > 0:54:28When nice people like you don't call the police, that's unusual.
0:54:28 > 0:54:32When you start moving dead bodies, that's just plain weird.
0:54:34 > 0:54:37I don't want an explanation. I just want paying.
0:54:41 > 0:54:44MOBILE RINGS
0:54:55 > 0:54:57SHE KNOCKS
0:56:47 > 0:56:49VEHICLE APPROACHES
0:56:57 > 0:57:00VEHICLE REVS LOUDLY
0:57:00 > 0:57:03CRASHING Argh!
0:57:14 > 0:57:16Argh! CRUNCHING
0:57:23 > 0:57:26HE GASPS
0:57:36 > 0:57:39If this is the same killer, he's learning fast.
0:57:39 > 0:57:42We know from Lucy that you blow up when things don't go your way.
0:57:42 > 0:57:43Is that what happened to Beale?
0:57:43 > 0:57:46You were found innocent, so why did you change your name?
0:57:47 > 0:57:50And I know her well enough to know when she's lying.
0:57:50 > 0:57:52I think they've seen each other.
0:57:52 > 0:57:54It's very important you don't take any more calls, Jess.
0:57:54 > 0:57:56- The police will be tracking your phone.- What...?
0:57:56 > 0:58:00It's our worst decisions that define us, Nikki -
0:58:00 > 0:58:01they're the ones we have to live by.
0:58:01 > 0:58:08# Testator silens
0:58:08 > 0:58:17# Costestes e spiritu
0:58:17 > 0:58:25# Silentium. #
