Today on Cop School, a Cop School criminal has burgled this flat.

0:00:020:00:04

Will the cadets be able to track him down with the help of forensics?

0:00:040:00:09

This is going to test crime scene examination skills to the limit.

0:00:090:00:13

I'm Rav Wilding, this is Cop School.

0:00:130:00:16

Six wannabe coppers...

0:00:190:00:22

meet the world's oldest police force.

0:00:220:00:24

Their mission - to complete a unique training course.

0:00:240:00:30

But are these cadets tough enough to cut it in the Met?

0:00:300:00:34

Last time at Cop School, the cadets trained as traffic cops...

0:00:380:00:42

..and had to investigate a major collision to find who was at fault.

0:00:450:00:49

If we need further questions, we will ask for them.

0:00:490:00:52

It's 8am sharp, and even though the cadets are tired,

0:00:530:00:56

they have to be ready to spring into action at any moment.

0:00:560:00:59

In this show, the Cop School cadets will be immersed

0:00:590:01:02

in the world of crime scene examination and forensics.

0:01:020:01:06

They've been told they're on their way to meet their mentor.

0:01:060:01:09

Which is true.

0:01:090:01:11

Exactly how they meet their mentor might be a bit of a surprise.

0:01:110:01:15

'That's because he's here - slap bang in the middle of a crime scene.

0:01:150:01:19

'Far from being a dead body,

0:01:190:01:20

'he's alive, alert and ready to put the cadets through their paces.'

0:01:200:01:25

CAR ALARM RINGS

0:01:270:01:29

Hello. Can you hear me?

0:01:340:01:36

You have just broken the first rule of crime scene examination.

0:01:410:01:45

You never, ever contaminate a crime scene.

0:01:450:01:47

I'm Greig Trout, a Metropolitan Police Service crime scene examiner.

0:01:470:01:51

Whilst you're training here, I am your mentor.

0:01:510:01:53

Forensics is the science behind crime solving.

0:01:530:01:57

Using the latest technology and examination techniques,

0:01:570:02:00

the police can work out exactly what took place in a crime scene

0:02:000:02:04

by studying the evidence that the criminal left behind.

0:02:040:02:08

Greig Trout's been working in forensics in the Met for six years

0:02:080:02:12

and has worked with the police to solve hundreds of crimes.

0:02:120:02:16

But can the Cop School cadets learn enough about CSE for them

0:02:170:02:21

to succeed in the final challenge?

0:02:210:02:23

Every single piece of evidence left behind in a crime scene

0:02:230:02:27

is crucial to the investigation.

0:02:270:02:30

From something the size of a human body to the tiniest hair and fibre.

0:02:300:02:35

And even DNA, invisible to the naked eye.

0:02:350:02:39

In order to avoid contaminating a crime scene,

0:02:390:02:41

the cadets will have to wear personal protective equipment (PPE).

0:02:410:02:45

OK, cadets.

0:02:460:02:48

The work of a crime scene examiner can be precise and painstaking.

0:02:480:02:51

You must avoid disturbing and contaminating the crime scene.

0:02:510:02:55

For this test, we want you to get from one end to the other,

0:02:550:02:59

-using these special stepping plates.

-But, as this is Cop School,

0:02:590:03:03

there's going to be added pressure.

0:03:030:03:05

You're also going to carry your forensic case with you in one hand.

0:03:050:03:09

You're going to work in pairs. The first pair will be Megan and Sam.

0:03:090:03:15

Great!

0:03:150:03:17

As CSEs have to be efficient and quick at crime scenes,

0:03:170:03:21

Greig will be timing the cadets to see who gets across the fastest.

0:03:210:03:24

Three, two, one.

0:03:240:03:26

HE BLOWS WHISTLE

0:03:260:03:28

'Speed isn't the only factor.'

0:03:280:03:30

Give me the briefcase.

0:03:300:03:31

'If, at any time, the cadets contaminate the crime scene

0:03:310:03:34

'with either their suitcases or themselves, they will be penalised.

0:03:340:03:39

'They must be quick, efficient and, above all, careful.

0:03:390:03:42

'In a real crime scene, CSEs might use these stepping plates

0:03:420:03:46

'to minimise the disturbance caused to the crime scene floor.'

0:03:460:03:50

Don't let that case touch the floor.

0:03:500:03:52

-Did you get it?

-'Megan's lost balance and contaminated the crime scene.

0:03:520:03:58

'That's unlucky.' Well done, Megan! You're nearly there now.

0:03:580:04:02

Remember, all of those plates have to cross the line.

0:04:020:04:05

-Last plate.

-Good effort. Well done! Well done!

0:04:050:04:10

We slowly put it on the ground and we both slowly stepped...

0:04:100:04:14

-OK, Nathan, Jade. Three, two, one.

-HE BLOWS WHISTLE

0:04:140:04:18

Beat the time of the team in front of you.

0:04:180:04:22

'Having watched Megan and Sam,

0:04:220:04:23

'Jade and Nathan are craftily trying out a different technique.

0:04:230:04:27

'Although it may help them cross quickly,

0:04:270:04:29

'they are actually disturbing the crime scene twice as much.

0:04:290:04:32

'By creating two lines of stepping plates, side by side,

0:04:320:04:37

'Nathan and Jade are creating a wider field of disturbance.

0:04:370:04:40

'And possible contamination of evidence.

0:04:400:04:42

'Many different specialists are involved in examining the scene.

0:04:420:04:47

'That's why it's important there's only one route through it.'

0:04:470:04:52

Nearly there! You can see the tape.

0:04:520:04:54

'And they're across.' Nice finish! Not bad.

0:04:540:04:59

'Last up, it's Junior and Rebecca.'

0:04:590:05:02

You're not going in that crime scene till you're correctly dressed.

0:05:020:05:06

'And they've already contaminated the crime scene.

0:05:060:05:10

'It's essential their protective clothing is worn properly.'

0:05:100:05:14

Not a good start! 'That mistake could cost them.'

0:05:140:05:17

OK, come on. Catch-up that time you just lost putting your hoods up.

0:05:170:05:20

'Wearing the PPEs may be uncomfortable for the cadets,

0:05:200:05:24

'especially in such a physical challenge.'

0:05:240:05:26

-Keep your balance!

-Go, Junior!

0:05:260:05:28

'But part of being a CSE is to leave no trace of yourself behind.

0:05:280:05:34

'Not a hair from your head or a fibre from your clothes.'

0:05:340:05:37

You're doing really well.

0:05:370:05:39

'Be careful there, Junior! Don't lose your balance.

0:05:390:05:43

'And it looks like Junior's shoe cover has come off.

0:05:430:05:46

'So close to the end. That's a schoolboy error.'

0:05:460:05:49

You're almost there. Last one.

0:05:490:05:51

I'm annoyed because my shoe came off.

0:05:530:05:56

-The pedals were so small, I couldn't keep both my feet in.

-It's OK.

0:05:560:06:00

We did OK. We did good.

0:06:000:06:02

Really irritated me.

0:06:020:06:03

OK, guys, who's ready for some results?

0:06:050:06:08

-Yeah.

-So, Megan and Sam, 3 minutes 10 seconds.

0:06:080:06:13

Rebecca and Junior with 2 minutes 16.29 seconds.

0:06:150:06:20

'That 0.29 could be important.'

0:06:200:06:24

Nathan and Jade, 2 minutes 16.19 seconds.

0:06:240:06:29

-Yes!

-Well done!

0:06:290:06:31

THEY SING

0:06:310:06:34

Very, very, very sad.

0:06:340:06:37

Ta-da!

0:06:380:06:39

With the physical activities out of the way,

0:06:420:06:45

it's time to engage their minds.

0:06:450:06:47

Forensics is a test of brain power.

0:06:470:06:50

A CSE will have to recreate in their minds

0:06:500:06:52

the events that happened during the crime.

0:06:520:06:54

Greig has set up this fake crime scene

0:06:540:06:58

to introduce the cadets to the basics of CSE.

0:06:580:07:01

As a crime scene examiner, we attend crime scenes

0:07:010:07:04

from anything from a murder to a burglary.

0:07:040:07:07

We'll retrieve any evidence that might be there.

0:07:070:07:09

That evidence is labelled and bagged.

0:07:090:07:11

That exhibit can then be presented at court.

0:07:110:07:13

There are three main steps to take when entering a crime scene -

0:07:130:07:18

secure, spot and save.

0:07:180:07:20

We only want people that are involved in a crime scene going in and out.

0:07:200:07:23

The first thing we've got to do is secure the crime scene.

0:07:230:07:26

Remember we learned about contamination?

0:07:260:07:27

That's exactly what we're trying to do with this.

0:07:270:07:30

Private investigation!

0:07:300:07:32

Then we'll conduct a walk through. We'll walk through the scene

0:07:320:07:35

and try and figure out what the suspect's movements have been.

0:07:350:07:38

It looks like someone's tried to find something valuable.

0:07:380:07:41

They've gone over there, come round here,

0:07:410:07:43

knocked that down and gone there.

0:07:430:07:45

Someone might be looking for files, like.

0:07:450:07:49

Anything that a CSE deems to be important to the case

0:07:490:07:53

must be numbered with cones.

0:07:530:07:56

Photograph the scene. What they've touched, what they've disturbed.

0:07:560:07:59

The key is to photograph the item in close-up and at a distance,

0:07:590:08:03

to provide as much information for the jury as possible.

0:08:030:08:06

Guys, well done. That's brilliant.

0:08:060:08:09

Absolutely fantastic.

0:08:090:08:10

Forensics teams are made up of many different types of experts,

0:08:150:08:18

who all specialise in different areas

0:08:180:08:21

of retrieving and gathering evidence.

0:08:210:08:24

Having learned the basics in CSE, it's now time

0:08:240:08:27

for our cadets to delve deeper into the world of forensics.

0:08:270:08:30

They will now learn to retrieve the most crucial types of evidence -

0:08:300:08:34

evidence that will lead the suspect

0:08:340:08:36

to the scene of a crime and ultimately find them guilty.

0:08:360:08:40

Greig has split the cadets into two teams.

0:08:410:08:43

Team One will focus on the retrieval of tool and footwear marks.

0:08:430:08:48

Team Two will learn how to retrieve fingerprints, hairs and fibres.

0:08:480:08:53

Here we're going to make some casts of footwear marks.

0:08:530:08:56

It's one of the best sources of evidence we can get.

0:08:560:08:59

Like a fingerprint, a footwear mark has different pieces

0:08:590:09:02

of wear and damage in the sole of it that makes it unique to that shoe.

0:09:020:09:06

So we can match a suspect with a crime scene mark.

0:09:060:09:09

Retrieving a footprint is a little like making a cake.

0:09:090:09:13

It takes a specific number of ingredients

0:09:130:09:16

and a specific order in which to mix them.

0:09:160:09:18

First, a soft surface and a suspect's footprint.

0:09:180:09:22

Give it a coating of sticky hairspray

0:09:220:09:24

to help keep the shape intact.

0:09:240:09:26

-Lovely.

-Add a metal dan, then combine one bag of pink plaster of Paris

0:09:260:09:32

with a small jug of water and mix thoroughly.

0:09:320:09:34

It's really mushy.

0:09:340:09:37

Don't let it set, Nathan.

0:09:370:09:39

I want to make sure it doesn't come out.

0:09:390:09:41

Next carefully - carefully...

0:09:410:09:44

cut the bag and pour the mixture into the footprint.

0:09:440:09:48

You never put it in properly.

0:09:480:09:50

I'd worry about your own, Nathan.

0:09:500:09:52

You know what happens to crown stone if you don't keep mixing it.

0:09:520:09:56

It's not come out!

0:09:560:09:58

-Yep.

-I need more water.

0:09:580:10:00

I think you need a bit more than that, Nathan.

0:10:000:10:03

While our scientific chefs wait for their shoe moulds to set,

0:10:030:10:06

let's catch up with Team B,

0:10:060:10:09

who are currently at another fake crime scene,

0:10:090:10:11

dusting for those all-important fingerprints.

0:10:110:10:14

That's really clear, Junior.

0:10:140:10:15

Your fingerprints are unique to you.

0:10:150:10:17

There are no two sets of fingerprints the same,

0:10:170:10:20

which means any found at a crime scene could incriminate a suspect.

0:10:200:10:24

This is the most important tool in your case.

0:10:240:10:27

It can light up anything. It reflects that finger mark right back at you.

0:10:270:10:31

Torch aside, you still need a keen eye, Megan.

0:10:310:10:34

I can't find any!

0:10:340:10:36

Yes, you can. Keep looking!

0:10:360:10:39

'Once spotted, a delicate brush with aluminium powder

0:10:390:10:42

'will bring that sweaty fingerprint to life.'

0:10:420:10:46

You might want a little bit less powder than that.

0:10:460:10:49

'Oh, dear, Megan.'

0:10:490:10:51

Next, a strip of sticky tape - minus that large air bubble, Junior -

0:10:510:10:55

can be used to lift the coated fingerprint from the glass.

0:10:550:10:59

Fantastic.

0:10:590:11:01

It's then rollered onto a plastic sheet and documented.

0:11:010:11:05

Back with Team A, and time for the big reveal.

0:11:050:11:09

Very good. Nice.

0:11:090:11:12

-Erm...

-Shut up, Jade!

0:11:120:11:15

Now all it takes is a quick brush down

0:11:160:11:19

and the footwear mark is revealed.

0:11:190:11:21

Very good, Sam. That's a good mark.

0:11:210:11:23

Great cast, Jade.

0:11:230:11:24

Good detail, Sam. And, Nathan, maybe you'll do better next time.

0:11:240:11:29

OK, this method's called electrostatic lifting.

0:11:290:11:32

We use it for dusty marks on hard surfaces.

0:11:320:11:36

You can also use it on carpet. It brings up anything with dust on it.

0:11:360:11:39

It attaches itself to a sheet of foil

0:11:390:11:42

from which we can get a perfect footwear mark.

0:11:420:11:45

First, the CSE needs a piece of mylar foil,

0:11:450:11:48

cut to the size of a footprint.

0:11:480:11:51

Thank you.

0:11:510:11:53

Next, add an earthing plate to conduct the electricity, and a

0:11:530:11:55

path finder, a special instrument that supplies electrical charge.

0:11:550:12:01

Then switch it on.

0:12:010:12:02

The electricity then sucks the foil to the surface and attracts the dust

0:12:020:12:07

to it, producing the perfect print.

0:12:070:12:09

But not all the retrieval methods in CSE involve

0:12:090:12:13

strawberry milkshake-coloured gunge and electricity.

0:12:130:12:16

For some, it's simply a pair of tweezers and sticky tape.

0:12:160:12:19

Hairs and fibres can match a suspect's clothing

0:12:190:12:23

with any hairs and fibres found on a surface.

0:12:230:12:26

They may not look like much but under the microscope,

0:12:260:12:29

hair and fibres offer a

0:12:290:12:31

wealth of information, from the type of clothing worn to a person's DNA.

0:12:310:12:36

That's it. Keep going.

0:12:360:12:38

It's like spaghetti, isn't it?

0:12:380:12:40

'Sorry, guys, it may not look exciting,

0:12:400:12:43

'but it's a crucial part of being a CSE.

0:12:430:12:46

'Any one of those hairs or fibres could match

0:12:460:12:48

'with those taken from a suspect. So stay sharp, cadets.

0:12:480:12:51

'You're the brains of this outfit.

0:12:510:12:55

'For the final lesson of the day,

0:12:550:12:57

'Team A are concocting one last forensic dish.

0:12:570:13:01

'It's tool mark surprise.'

0:13:010:13:02

If you've got a burglar who's broken in through a window

0:13:020:13:05

-using a screwdriver or a crowbar...

-'Or a spade, Greig.'

0:13:050:13:09

..that will leave tiny marks on the surface that we need to get hold of.

0:13:090:13:13

'The cadets will need some putty, or silly putty in Nathan's case...

0:13:130:13:17

Everyone else gets a ball. I get a sausage!

0:13:170:13:21

'..some glue and some hardening gel.

0:13:210:13:25

'First mould a piece of Plasticine into a small dome shape

0:13:250:13:28

'and stick it beneath the tool mark.

0:13:280:13:30

'This will help catch any unwanted spillage.'

0:13:300:13:32

There you go, squeeze it on.

0:13:320:13:35

'Next, the paste. Put 40ml of glue into a small pot.'

0:13:350:13:40

-It looks like ice cream.

-I can assure you it's not.

0:13:400:13:42

-Eight drops of hardening gel...

-Whoa.

0:13:420:13:46

..and mix carefully. Be careful, though.

0:13:460:13:48

Once the hardening gel is added, it's not long before it sets.

0:13:480:13:53

Where have I seen this go wrong before, Nathan?

0:13:530:13:56

Once thick, it's time to coat that tool mark.

0:13:560:13:59

Take the gloop and cover that indentation.

0:13:590:14:02

Apply more until the paste is set. Unless of course...

0:14:020:14:05

What's happening, Nathan?

0:14:070:14:09

'..it's already set.'

0:14:090:14:11

-Oh, no!

-'Again.'

0:14:110:14:13

-Did you put too much of that stuff in?

-Yeah.

0:14:130:14:16

If you did get it right, then once the paste is set,

0:14:160:14:19

it's simply a matter of carefully peeling off the mould,

0:14:190:14:22

checking the indentation,

0:14:220:14:23

and popping it in an evidence box ready to be posted to the lab.

0:14:230:14:27

'Congratulations, cadets.

0:14:310:14:33

'That was a lot to take in. You've successfully completed forensics training.'

0:14:330:14:37

Now it's time to select our leader.

0:14:370:14:40

So today's leader is going to be Junior.

0:14:400:14:44

13-year-old Junior from Birmingham loves playing all sports.

0:14:460:14:50

Three, four...

0:14:500:14:51

He's a talented drummer and definitely has the confidence.

0:14:510:14:54

I don't think I'm going to struggle.

0:14:540:14:56

I know what's coming and I'm ready for it.

0:14:560:14:58

But is he ready to lead a team of Cop School cadets?

0:14:580:15:02

While Junior loves being leader, over in a nearby neighbourhood

0:15:020:15:06

a crime has just been reported to the police.

0:15:060:15:09

I came back home as normal to find my door was open.

0:15:090:15:12

I found a man rifling through my things.

0:15:120:15:15

He ran out, dropped his sunglasses.

0:15:150:15:16

I looked round to see what was missing.

0:15:160:15:19

A necklace, laptop, wallet, watch, phone.

0:15:190:15:21

He'd even taken lemonade out of the fridge.

0:15:210:15:24

When he ran out, I never saw him again.

0:15:240:15:26

"Cadets, there's been a burglary at a nearby flat.

0:15:260:15:30

"Get to the scene of the crime as quickly as possible,

0:15:300:15:33

"taking everything you need to assess the scene and examine the evidence."

0:15:330:15:36

Got it. Thanks. Let's go.

0:15:360:15:38

Before they leave, it's crucial Junior makes sure

0:15:380:15:41

they have all the equipment they're going to need.

0:15:410:15:44

-Have we got the crime stone?

-It's all in there.

0:15:460:15:49

It's all in there. All right, let's go.

0:15:490:15:52

Good leadership, Junior.

0:15:520:15:53

With the equipment check now done, it's off to the scene of the crime.

0:15:530:15:57

Earlier, a Cop School criminal committed a burglary here in this flat.

0:16:010:16:05

As he searched the rooms for things to steal,

0:16:050:16:08

he left behind eight pieces of evidence

0:16:080:16:10

which the cadets will have to find, photograph and retrieve.

0:16:100:16:14

This is where they are.

0:16:160:16:17

On the front door, both shoe and tool marks.

0:16:170:16:20

In the hallway, a foot mark and some glasses.

0:16:200:16:25

In the kitchen, an open bottle.

0:16:250:16:28

In the lounge, fingerprints on the coffee table.

0:16:280:16:31

And in the bedroom, fingerprints on the window ledge

0:16:310:16:35

and fibres on the chair.

0:16:350:16:37

But will they remember everything they've been taught by mentor Greg?

0:16:370:16:41

Come on, guys.

0:16:410:16:42

Team leader Junior has split them into teams of two,

0:16:420:16:45

allocating different roles to each pair.

0:16:450:16:48

Acting as senior forensic practitioners are Megan and Rebecca.

0:16:480:16:52

They're responsible for spotting and marking evidence

0:16:520:16:55

and, later, dusting for prints.

0:16:550:16:57

Sam and Nathan are the assistant forensic practitioners

0:16:570:17:00

and will be retrieving tool marks and shoe marks.

0:17:000:17:04

Jade and Junior will be the photographers.

0:17:040:17:07

Come on, let's go. Let's go to work, come on.

0:17:070:17:09

Both myself and mentor Greg

0:17:100:17:13

will be keeping a very close eye on the cadets.

0:17:130:17:16

There's a camera in every room of the flat,

0:17:160:17:19

so from here, we can see every element of the cadets' search.

0:17:190:17:23

First into the crime scene are Megan and Rebecca.

0:17:230:17:26

Hopefully they've learned to be careful when they go into the scene.

0:17:260:17:30

Secure it. Figure out what evidence they're going to get.

0:17:300:17:33

OK, it's safe to stand here.

0:17:340:17:37

Watch where you're stepping, though.

0:17:370:17:40

Good call, Megan.

0:17:400:17:41

There's an important piece of evidence right beside your foot.

0:17:410:17:45

Let me know everything...

0:17:450:17:46

But they've walked straight past it.

0:17:460:17:48

That footprint could be a clue as to how the criminal entered the flat.

0:17:480:17:52

There's a broken, shattered glass beside the window.

0:17:540:17:58

-How does it look? Is it outside or inside?

-Is it the window glass?

0:17:580:18:03

Junior is thinking the criminal may have broken into the flat through the window.

0:18:030:18:07

Does it look like someone's come through there?

0:18:070:18:10

No, the window's shut and the curtains are closed over,

0:18:100:18:13

-so he couldn't have got through the window.

-OK.

0:18:130:18:17

It's a logical guess, but it's not right.

0:18:170:18:20

The glass is from an empty vase knocked over by the Cop School criminal.

0:18:200:18:24

Moving into the bedroom.

0:18:240:18:26

The curtains are all crumpled up and the window is open.

0:18:260:18:31

That's a good spot from Megan.

0:18:310:18:33

The Cop School criminal was here

0:18:330:18:35

and he did leave valuable evidence behind.

0:18:350:18:37

This is the lounge.

0:18:370:18:39

So... There's fingerprints on the glass table in the lounge.

0:18:390:18:45

Fingerprints on the table.

0:18:450:18:47

"Put a cone on it."

0:18:470:18:49

-"Already done. Over."

-Already done!

0:18:490:18:52

You're doing a very good job. Carry on. Don't miss anything.

0:18:520:18:57

-Thank you.

-Morale-boosting the troops, that's what we like to see.

0:18:570:19:01

Fantastic work, Junior.

0:19:010:19:03

They said that the victim dropped something,

0:19:030:19:06

so I'm wondering is there anything dropped?

0:19:060:19:09

Good question, Junior. He's referring to the sunglasses

0:19:090:19:12

the witness said the criminal dropped.

0:19:120:19:15

Found a man rifling through my things.

0:19:150:19:17

He ran out, dropped his sunglasses on the way.

0:19:170:19:20

It looks like Rebecca has found them.

0:19:210:19:24

"We have a pair of sunglasses."

0:19:240:19:26

Put a cone on it.

0:19:260:19:28

Those sunglasses could provide vital DNA if it can be retrieved later on.

0:19:280:19:33

It's not a bad effort from our senior forensic practitioners.

0:19:330:19:37

So, they've found three crucial bits of evidence.

0:19:390:19:42

Fingerprints in the lounge,

0:19:420:19:43

fingerprints in the bedroom,

0:19:430:19:45

sunglasses in the hallway.

0:19:450:19:47

But they're still missing five other pieces of evidence,

0:19:470:19:50

including that footprint right in front of the door.

0:19:500:19:53

Will the cadets spot it?

0:19:530:19:55

Here come the photographers.

0:19:570:19:59

Jade's straight in there, taking photographs of the sunglasses but...

0:19:590:20:05

The footwear mark - doesn't look like it's been spotted.

0:20:050:20:08

And unfortunately, Junior's just stood right on top of it.

0:20:080:20:12

Not the greatest start.

0:20:120:20:14

"Taking a picture of the table."

0:20:140:20:17

Make sure you take a picture wide and take a picture zoomed.

0:20:200:20:23

That's good to hear. Nathan's reminding the photographers

0:20:230:20:27

of the importance of the long lens and the close-up pictures.

0:20:270:20:32

Here, here.

0:20:330:20:35

Looks like Jade's on to something.

0:20:350:20:37

We found an open substance in a glass bottle

0:20:370:20:40

and we found a few open wine bottles.

0:20:400:20:44

Didn't the victim say that he never opened a bottle?

0:20:440:20:49

Did he say that he never opened any drinks?

0:20:490:20:53

Rebecca's saying take pictures of the bottles.

0:20:530:20:56

Outstanding communication from the cadets -

0:20:560:20:59

and they're absolutely right.

0:20:590:21:00

It WAS the Cop School criminal

0:21:000:21:03

and this bottle is a solid piece of evidence.

0:21:030:21:05

It looks as though our forensic photographers might be on a roll.

0:21:070:21:11

Yep. Look, can you see that glimpse of hair there?

0:21:110:21:15

See?

0:21:170:21:18

Yep?

0:21:210:21:22

We found some hair in the bedroom on the seat.

0:21:220:21:26

What room is that in?

0:21:260:21:28

-The bedroom.

-OK.

0:21:280:21:31

The Cop School criminal did sit in this chair.

0:21:310:21:34

That's one of the most difficult spots to find.

0:21:340:21:38

Sam's going to go in. Is that OK?

0:21:380:21:41

Yeah, no problem.

0:21:410:21:42

On the way back, look for any footprints that we can see, OK?

0:21:420:21:46

We'll take a picture.

0:21:460:21:47

In the hallway now.

0:21:470:21:49

See if they notice the footwear mark.

0:21:490:21:52

Here we go. They're taking a picture.

0:21:520:21:54

Excellent. Brilliant.

0:21:540:21:56

Finally, that elusive footwear mark.

0:21:560:21:58

Better late than never.

0:21:580:22:00

They got it and they're taking photos.

0:22:000:22:02

We want to see it lifted now.

0:22:020:22:04

Well done, photographers. You've done a great job.

0:22:060:22:10

So now with six pieces of evidence marked and photographed,

0:22:100:22:14

it's the job of the retrieval team -

0:22:140:22:16

made up of Sam, Nathan, Megan and Rebecca -

0:22:160:22:19

to go into the crime scene and extract that evidence.

0:22:190:22:22

However, they still need to be observant.

0:22:220:22:25

Let's go to the living room.

0:22:250:22:26

There are still two more pieces of evidence they haven't found.

0:22:260:22:30

Megan and I are in the living room.

0:22:320:22:34

Megan's taking fingerprints on the glass table.

0:22:340:22:37

I'm going to check for hairs on the sofa.

0:22:370:22:39

This will be a big test for Megan,

0:22:390:22:42

as she didn't do all that well at fingerprint retrieval in training.

0:22:420:22:46

Over with Sam and Nathan, their test is what they can remember

0:22:460:22:49

from foot mark retrieval.

0:22:490:22:52

They're going to do the electrostatic lift

0:22:520:22:55

of the footwear mark that they've got on the hallway.

0:22:550:22:59

They've got the foil down, the earthing plate

0:22:590:23:02

and now the path finder.

0:23:020:23:04

Nice and slow.

0:23:040:23:06

Very impressed with them so far.

0:23:060:23:08

It's a very technical procedure.

0:23:080:23:11

Make sure you don't touch the metal.

0:23:110:23:13

It's now...

0:23:140:23:16

a question of whether it's lifted the mark or not. It's looking good.

0:23:160:23:21

-Think that's worked?

-Yeah, yeah.

0:23:210:23:24

Great retrieval, guys.

0:23:240:23:26

If the police find the suspect, this could help convict him.

0:23:260:23:30

Back in the living room, it looks like Megan is about to do exactly the same.

0:23:300:23:34

We've got three fingerprints.

0:23:340:23:37

She's got it. That to me is very nice. That's so clear from here.

0:23:370:23:42

Megan's retrieved those fingerprints perfectly.

0:23:420:23:45

If there's a match on the database,

0:23:450:23:47

the police will know exactly who to arrest.

0:23:470:23:50

You're doing a very good job.

0:23:500:23:52

Junior and his team of forensic practitioners have stepped it up a gear.

0:23:520:23:56

What about the dirt?

0:23:560:23:57

Sam has found the footwear mark on the door,

0:23:570:24:00

which should lead him to the tool marks, too.

0:24:000:24:03

What about this? This is a bit...

0:24:030:24:06

He's had a go with the tool, hasn't he?

0:24:060:24:08

It has. Congratulations, cadets.

0:24:080:24:10

That's all eight pieces of evidence discovered.

0:24:100:24:14

Yeah!

0:24:160:24:17

Now the cadets must retrieve as much of the evidence as they can

0:24:170:24:21

with what little time remains.

0:24:210:24:23

I think I've got a fingerprint on the metal bit of the window.

0:24:230:24:27

-That's brilliant work.

-'That's another essential find from Megan.'

0:24:270:24:31

Got a fingerprint in the bedroom on the windowsill.

0:24:310:24:34

If these fingerprints match the ones in the lounge,

0:24:340:24:37

the evidence will be stacked up against the suspect.

0:24:370:24:40

Nathan!

0:24:400:24:42

I've done it.

0:24:420:24:43

Just seeing how Sam... He looks a bit nervous

0:24:430:24:46

but he's taking off his tool mark.

0:24:460:24:48

-I think it's hard enough. It won't get harder.

-The clock is ticking.

0:24:480:24:53

Got some of it.

0:24:530:24:55

He's got it and in one piece. He's done a good job.

0:24:550:24:58

-Looks like it from here.

-It looks like it set very nicely.

0:24:580:25:02

Guys, quickly. We've only got one minute left.

0:25:020:25:06

With time almost up, Megan packages up another great set of fingerprints.

0:25:060:25:11

The cadets can be happy with their performance

0:25:110:25:14

as they managed to spot all eight pieces of evidence

0:25:140:25:17

and retrieve five.

0:25:170:25:18

-Great, guys. Well done.

-Well done, everyone.

0:25:180:25:22

Despite failing to retrieve evidence from the bottle in the kitchen,

0:25:220:25:25

the chair in the bedroom and the sunglasses in the hall,

0:25:250:25:29

Megan's excellent fingerprint retrieval

0:25:290:25:31

led to a positive match in the Cop School database,

0:25:310:25:34

so it won't be long before this known criminal is back behind bars.

0:25:340:25:38

OK, Greg. They all did well on that challenge, it's fair to say.

0:25:400:25:44

But some stood out a little bit more. Let's start with Megan.

0:25:440:25:48

She did really well. She found the fingermarks on the table,

0:25:480:25:51

the fingermarks on the windowsill.

0:25:510:25:53

She was really thorough in how she retrieved and examined them.

0:25:530:25:57

-Junior?

-He did really well.

0:25:570:26:00

He asked questions of everyone.

0:26:000:26:02

He delegated responsibility.

0:26:020:26:04

He made sure everyone was all right, which was a great way

0:26:040:26:08

of keeping his team's morale going and keeping them on track.

0:26:080:26:11

Someone else who did a good job was Sam.

0:26:110:26:13

He was fantastic. Really good.

0:26:130:26:16

He retrieved the footwear mark using the electrostatic lifting technique.

0:26:160:26:20

He also did the tool mark on the door perfectly.

0:26:200:26:23

Fantastic stuff.

0:26:230:26:25

OK, cadets.

0:26:250:26:27

This has been a very tough decision, but Greg and I have made it.

0:26:270:26:32

We've decided that today there are in fact going to be two top cops.

0:26:320:26:37

Now, those top cops are going to have

0:26:370:26:42

a smashing time destroying some of the CSE sugar glass.

0:26:420:26:49

-However...

-A punishment.

0:26:500:26:52

There will be a punishment for the rest of you.

0:26:520:26:55

That will be cleaning out the CSE van.

0:26:550:26:59

-Which is a mess.

-No way.

0:26:590:27:01

You're kidding.

0:27:010:27:03

So the two top cadets for today are...

0:27:030:27:07

-Megan.

-Ooh!

0:27:140:27:17

And Sam. Well done.

0:27:170:27:19

Well done.

0:27:190:27:21

Well done.

0:27:210:27:23

Next time at Cop School,

0:27:240:27:26

the cadets deal with virtual crowds in public order.

0:27:260:27:29

There's lots to shout about in training.

0:27:310:27:33

And they control a Cop School riot that gets out of hand.

0:27:350:27:38

Go!

0:27:380:27:39

Remember, this is sugar glass so don't try this at home.

0:27:400:27:44

Go on, Megan.

0:27:440:27:47

Yeah!

0:27:470:27:48

Go on, Sam. Go on!

0:27:480:27:51

Yeah!

The cadets are being trained in crime scene examination. Lifting fingerprints, hairs and fibres, electrostatic footwear lifts and toolmark casting - they have to master all these techniques and more, in time to successfully carry out a forensic search following a Cop School burglary. Wearing full forensics PPE suits, the heat is really on - so who will their mentor Rav Wilding decide is the top cop?
