0:00:17 > 0:00:22- Tonight, I hear how the remains - of a female dancer in the Gower...
0:00:22 > 0:00:25- ..were found - 40 years after she disappeared.
0:00:27 > 0:00:31- And I hear about the North Wales - Police's investigation...
0:00:31 > 0:00:34- ..into a skeleton found in woodland.
0:00:35 > 0:00:38- We have to find out who he was...
0:00:38 > 0:00:41- ..what happened to him and why.
0:01:04 > 0:01:06- Caswell Bay in the Gower.
0:01:06 > 0:01:10- It was near this beach in 1961...
0:01:10 > 0:01:15- ..that detectives solved a mystery - that had baffled police for decades.
0:01:23 > 0:01:26- In November, three local men...
0:01:27 > 0:01:30- ..explored a cave near - the former lead mine at Brandy Cove.
0:01:31 > 0:01:33- It was there, in a hidden chamber...
0:01:33 > 0:01:37- ..that they discovered - a pile of human bones.
0:01:41 > 0:01:44- I could see a round skull...
0:01:44 > 0:01:47- ..lying on top of the boulders.
0:01:47 > 0:01:50- So I picked it up - and turned it around...
0:01:50 > 0:01:53- ..and it appeared to be - a human skull.
0:01:59 > 0:02:02- One of the men - removed the skull from the cave...
0:02:02 > 0:02:04- ..and took it to the police.
0:02:04 > 0:02:10- Following on from that, - a pathologist entered the cave...
0:02:10 > 0:02:12- ..and removed all the bones.
0:02:13 > 0:02:15- It was clear to the pathologist...
0:02:15 > 0:02:21- ..that the body had been dismembered - in three parts with a saw.
0:02:22 > 0:02:26- They suspected the body - had been there for some years.
0:02:26 > 0:02:29- There were further clues - inside the cave.
0:02:32 > 0:02:34- Beside the bones...
0:02:34 > 0:02:37- ..was a hairbrush, rings...
0:02:37 > 0:02:42- ..and tassels that had detached - from the person's clothes.
0:02:46 > 0:02:49- As detectives - tried to identify the body...
0:02:49 > 0:02:53- ..they were told - of a missing person in the area.
0:02:54 > 0:02:56- 40 years earlier...
0:02:57 > 0:03:00- ..a woman - named Mamie Stuart disappeared.
0:03:02 > 0:03:06- Born and raised - in Sunderland in 1893...
0:03:06 > 0:03:10- ..she left home, aged 16, - to pursue a stage career.
0:03:12 > 0:03:16- She was a very talented girl. - She could sing and dance.
0:03:16 > 0:03:19- She had her heart set - on the stage.
0:03:21 > 0:03:24- She found work as a chorus girl - and was part of a group...
0:03:25 > 0:03:27- ..called the Five Verona Girls.
0:03:35 > 0:03:39- In 1917 she met - marine surveyor George Shotton.
0:03:43 > 0:03:46- He was older than her, - a professional man...
0:03:46 > 0:03:49- ..who was, by all accounts, - respectable.
0:03:50 > 0:03:53- They fell in love - and got married after a year.
0:03:54 > 0:03:57- They moved around the country...
0:03:57 > 0:04:01- ..until they - eventually settled in Swansea.
0:04:02 > 0:04:06- George Shotton - had found work in the city.
0:04:06 > 0:04:10- They moved to a house - on Newton Road in the Mumbles.
0:04:13 > 0:04:17- It was clear at the beginning of - the marriage that she was unhappy.
0:04:20 > 0:04:22- She was spotted on the beaches...
0:04:23 > 0:04:26- ..of Mumbles and Caswell Bay...
0:04:26 > 0:04:28- ..looking forlorn.
0:04:28 > 0:04:31- On top of that, - she wrote letters home...
0:04:31 > 0:04:36- ..suggesting to her parents - that it was an unhappy marriage...
0:04:37 > 0:04:39- ..and that she wanted to end it.
0:04:41 > 0:04:45- She made one very strange remark.
0:04:45 > 0:04:49- She said, - "If I should ever go missing...
0:04:49 > 0:04:53- "..will you make sure - that you go looking for me?"
0:04:53 > 0:04:56- And that's what happened - - she disappeared.
0:04:58 > 0:05:02- After her suitcase was discovered - at a Swansea hotel...
0:05:02 > 0:05:04- ..her parents phoned the police.
0:05:05 > 0:05:09- Officers searched for her - in Caswell Bay.
0:05:09 > 0:05:11- There was no sign of Mamie.
0:05:19 > 0:05:24- Newspaper stories suggested that - Mamie Stuart had moved overseas....
0:05:24 > 0:05:26- ..to start a new life.
0:05:26 > 0:05:29- Some claimed - to have seen her in New York.
0:05:29 > 0:05:33- Friends of the family claimed - they'd seen her in India in 1923.
0:05:33 > 0:05:38- In reality, Mamie's disappearance - was a complete mystery to everyone.
0:05:45 > 0:05:48- The police - questioned George Shotton.
0:05:48 > 0:05:51- They discovered - that he lived a secret life.
0:05:53 > 0:05:56- Unbeknown to Mamie, - George had another wife...
0:05:56 > 0:05:58- ..who lived in Caswell Bay.
0:05:58 > 0:06:00- They had a child together.
0:06:00 > 0:06:04- George told police he'd - had a relationship with Mamie...
0:06:04 > 0:06:07- ..but insisted they weren't married.
0:06:07 > 0:06:11- He said they'd separated - and Mamie had moved out of the area.
0:06:14 > 0:06:18- Though the police - doubted George Shotton's evidence...
0:06:19 > 0:06:22- ..without a body, - there was no proof.
0:06:23 > 0:06:26- However, he was arrested - and found guilty of bigamy.
0:06:27 > 0:06:31- He was sentenced to 18 months - of hard labour in prison.
0:06:36 > 0:06:39- South Wales Police - retain details of serious cases...
0:06:40 > 0:06:42- ..and any forensic evidence.
0:06:43 > 0:06:47- In 1961, police collected the items - found beside the body...
0:06:48 > 0:06:50- ..in Brandy Cove...
0:06:50 > 0:06:55- ..including rings, ribbons - and other jewellery.
0:06:59 > 0:07:03- In this box is a chain, - a safety pin, fasteners...
0:07:03 > 0:07:05- ..and a pearl button.
0:07:06 > 0:07:10- We know - from Mamie's friends and family...
0:07:10 > 0:07:14- ..that these are the type of things - she wore on her clothes...
0:07:15 > 0:07:17- ..especially the button.
0:07:20 > 0:07:23- For the police in the 1960s...
0:07:23 > 0:07:27- ..there was strong evidence - to suggest this was Mamie's body.
0:07:28 > 0:07:30- We have a hair slide.
0:07:31 > 0:07:35- This was discovered - next to the bones.
0:07:35 > 0:07:40- The hair is brown, - the same colour as Mamie's hair.
0:07:43 > 0:07:45- These days, the victim's hair...
0:07:46 > 0:07:50- ..would deliver a DNA profile - and quick results for detectives.
0:07:50 > 0:07:52- But even in the 1960s...
0:07:53 > 0:07:57- ..police used the skull - to determine the shape of her face.
0:07:57 > 0:07:59- At the time, in 1961...
0:08:00 > 0:08:02- ..this is the technology they used.
0:08:03 > 0:08:06- By comparing the skull - that was discovered...
0:08:06 > 0:08:09- ..with a photograph - of Mamie Stuart...
0:08:09 > 0:08:13- ..they used an overlay, - and by doing that...
0:08:13 > 0:08:17- ..we can see that the overlay - fitted the photograph.
0:08:17 > 0:08:19- We know it was Mamie Stuart.
0:08:24 > 0:08:28- This is the Face Lab in Liverpool - which helps police forces...
0:08:28 > 0:08:32- ..to identify human remains - by concentrating on the face.
0:08:33 > 0:08:37- The techniques are very different - from those of the 1960s.
0:08:44 > 0:08:46- The first thing we do...
0:08:46 > 0:08:50- ..is establish the biological - profile of the remains.
0:08:50 > 0:08:55- The age, the sex of the individual, - the ethnic group, the ancestry.
0:08:55 > 0:08:57- We look at signs - of trauma or disease...
0:08:58 > 0:09:02- ..and we focus specifically - on prediction of facial features...
0:09:02 > 0:09:06- ..from analysis of the bones - of the face.
0:09:08 > 0:09:12- We've built up a process and - a database of scanned features...
0:09:12 > 0:09:15- ..and modelled muscles - that we can import...
0:09:15 > 0:09:20- ..and build the face, muscle - by muscle, feature by feature...
0:09:20 > 0:09:22- ..on to the 3D model from the scan.
0:09:25 > 0:09:30- Despite the advances, some aspects - are still difficult to determine.
0:09:34 > 0:09:37- Skin colour, eye colour, - hairstyle...
0:09:37 > 0:09:41- ..the number of wrinkles - texture - information is difficult to know.
0:09:41 > 0:09:45- We have to be careful when we - present this face to the public...
0:09:45 > 0:09:48- ..because we want it - to be recognized.
0:09:48 > 0:09:51- We produce an image - in black and white...
0:09:51 > 0:09:56- ..that the police can put out - to the public in a frontal view.
0:09:56 > 0:10:00- We focus on the centre of the face - and blur anything like hairstyle...
0:10:00 > 0:10:03- ..that we may not - feel confident about.
0:10:06 > 0:10:09- In the 1960s, - detectives were sure...
0:10:09 > 0:10:13- ..that the body at Brandy Cove - was that of Mamie Stuart.
0:10:13 > 0:10:17- But it was hard to prove - whether or not she was murdered.
0:10:17 > 0:10:22- The evidence of a local witness - proved vital to the inquest.
0:10:24 > 0:10:27- During the inquest - in December 1961...
0:10:27 > 0:10:31- ..a postman said he remembered - seeing George Shotton...
0:10:31 > 0:10:35- ..carrying a heavy sack - from his house to his car...
0:10:35 > 0:10:37- ..and driving towards Brandy Cove.
0:10:38 > 0:10:42- The jury decided that it was - Mamie's body inside the sack.
0:10:47 > 0:10:50- Pieces of sackcloth...
0:10:50 > 0:10:53- ..found near the bones - confirmed suspicions...
0:10:54 > 0:10:57- ..that George Shotton - had murdered her.
0:11:00 > 0:11:05- But when detectives went to - search for him, they were too late.
0:11:05 > 0:11:08- He'd died three years earlier...
0:11:08 > 0:11:10- ..aged 78.
0:11:12 > 0:11:16- On his release from jail, - George Shotton moved to England...
0:11:17 > 0:11:19- ..and lived a quiet life.
0:11:19 > 0:11:23- He died in April 1958 - at Southmead Hospital, Bristol.
0:11:23 > 0:11:25- A mere three years - after his death...
0:11:25 > 0:11:28- ..the truth about his secret - came to light...
0:11:28 > 0:11:32- ..and was widely reported - in the British press.
0:11:47 > 0:11:51- He never thought - Mamie Stuart would be found...
0:11:51 > 0:11:56- ..because the body was kept - in a chamber inside the cave.
0:11:57 > 0:12:01- It was purely down to luck...
0:12:02 > 0:12:05- ..that the men decided - to take that route into the cave.
0:12:08 > 0:12:12- Though it took 40 years - to find Mamie Stuart...
0:12:13 > 0:12:18- ..the mystery surrounding - her disappearance had been solved.
0:12:22 > 0:12:25- But for detectives in North Wales...
0:12:26 > 0:12:30- ..efforts to identify human remains - found in a forest continue.
0:12:41 > 0:12:41- .

0:12:42 > 0:12:44- Subtitles- - Subtitles
0:13:00 > 0:13:02- November 2015...
0:13:03 > 0:13:06- ..and North Wales Police - were called to Clocaenog Forest.
0:13:08 > 0:13:10- A discovery amongst the trees...
0:13:11 > 0:13:14- ..led to a case - full of mystery for detectives.
0:13:21 > 0:13:25- The Rally GB stage - of the World Rally Championship...
0:13:25 > 0:13:27- ..was held in the Llyn Brenig area.
0:13:28 > 0:13:33- Due to bad weather, some spectators - went in search of firewood.
0:13:33 > 0:13:37- They were shocked to find bones - in the soil beneath the trees.
0:13:39 > 0:13:42- When they took - a closer look with a torch...
0:13:42 > 0:13:47- ..one of them saw something - glistening under the moss.
0:13:50 > 0:13:53- As they entered this area here...
0:13:53 > 0:13:55- ..in this precise location...
0:13:55 > 0:13:57- ..one of them found a skull.
0:13:57 > 0:14:03- He phoned the police - to inform them he'd found a skull.
0:14:06 > 0:14:08- A pathologist arrived...
0:14:08 > 0:14:12- ..and confirmed it was - a human skull that they'd found.
0:14:12 > 0:14:16- Police found more bones - scattered in the earth.
0:14:21 > 0:14:25- The forensics' team - came to examine the entire area...
0:14:25 > 0:14:28- ..to try and find - the rest of the body.
0:14:28 > 0:14:31- As you can see...
0:14:31 > 0:14:33- ..this area had been cordoned off...
0:14:34 > 0:14:36- ..and we searched the inner cordon.
0:14:44 > 0:14:47- The forensics' team - spent five weeks...
0:14:47 > 0:14:51- ..searching every inch of the area - in all weathers...
0:14:51 > 0:14:53- ..to find any piece of evidence.
0:14:57 > 0:15:00- It was dense with trees, - the weather was dreadful.
0:15:00 > 0:15:03- It was difficult getting here.
0:15:03 > 0:15:07- Forestry workers - helped clear part of the forest.
0:15:07 > 0:15:11- It was very difficult - for the team to get here.
0:15:11 > 0:15:14- As soon as they arrived, - we started clearing.
0:15:14 > 0:15:19- They had to closely examine the - earth to find the entire skeleton.
0:15:19 > 0:15:23- One part of the skull...
0:15:23 > 0:15:27- ..was found higher up, which - suggests animals had been here...
0:15:27 > 0:15:29- ..and moved parts of the body.
0:15:34 > 0:15:38- A team of forensic anthropologists - studied the remains.
0:15:39 > 0:15:43- Specialist biologists studied - the growth of the trees and plants.
0:15:43 > 0:15:47- They took samples - of the earth as well as the roots.
0:15:47 > 0:15:52- We strongly suspect that the body - had been here for a long time.
0:15:52 > 0:15:54- We don't think it was buried here...
0:15:55 > 0:15:58- ..but we believe that plants, - leaves and branches...
0:15:59 > 0:16:02- ..were either laid on top of it - or that they'd fallen onto it.
0:16:05 > 0:16:08- After conducting tests - on the bones...
0:16:08 > 0:16:12- ..detectives had a profile - of the person found in the woods.
0:16:19 > 0:16:21- We took a DNA profile...
0:16:21 > 0:16:26- ..which showed it was a man - with a full profile.
0:16:26 > 0:16:29- We knew - it was the skeleton of a man.
0:16:29 > 0:16:33- Afterwards, they were able - to measure the man's height.
0:16:34 > 0:16:39- By now, - we know that it was a person...
0:16:39 > 0:16:43- ..of approximately - five foot eight inches...
0:16:43 > 0:16:46- ..to five foot - ten and a half inches tall.
0:16:46 > 0:16:51- We also believe that - he was at least 54 years of age.
0:16:53 > 0:16:54- Tests on the skull...
0:16:55 > 0:16:59- ..made detectives suspect - that it was a suspicious death.
0:17:07 > 0:17:10- As yet, - we don't know if he was killed....
0:17:10 > 0:17:13- ..but we're looking into - whether or not he was killed.
0:17:14 > 0:17:17- He'd certainly sustained - some sort of trauma to the head...
0:17:17 > 0:17:19- ..and another part of the body.
0:17:20 > 0:17:24- The next step was to establish - how long the body had been there.
0:17:25 > 0:17:26- Alright, boss?
0:17:26 > 0:17:30- I've got some photos - of the forest we've recently had....
0:17:30 > 0:17:33- ..regarding - this body deposition site...
0:17:33 > 0:17:38- ..in relation to the development - of the forest over the years.
0:17:38 > 0:17:40- They're excellent.
0:17:40 > 0:17:44- Aerial photographs - give detectives clues...
0:17:44 > 0:17:47- ..about the forest's history - since the 1970s.
0:17:47 > 0:17:50- We know - the forest had been replanted...
0:17:50 > 0:17:53- ..at the end of the 1980s.
0:17:54 > 0:17:59- It's likely that he wasn't deposited - there at that time...
0:17:59 > 0:18:03- ..because there was no forest - to conceal him.
0:18:11 > 0:18:15- The skeleton was discovered - near the village of Pentrellyncymer.
0:18:18 > 0:18:19- A remote location...
0:18:20 > 0:18:22- ..off the beaten track.
0:18:29 > 0:18:31- This area is very remote.
0:18:31 > 0:18:36- It makes you think that it's someone - with some connection to this place.
0:18:36 > 0:18:42- It might be a local or someone - who knows about this place.
0:18:44 > 0:18:48- It's very rare that someone - leaves a body somewhere...
0:18:48 > 0:18:51- ..with no knowledge - of the area itself.
0:18:56 > 0:19:00- But when the news broke, - no-one came forward with a name.
0:19:01 > 0:19:05- The detectives were still in the - dark, unable to identify the body.
0:19:11 > 0:19:14- As detectives, - we have to find out who he was...
0:19:14 > 0:19:17- ..in order to focus - on the victimology...
0:19:17 > 0:19:21- ..and work out - what happened to him and why.
0:19:21 > 0:19:23- Until we know who he was...
0:19:23 > 0:19:26- ..it's hard to know - what happened to him.
0:19:28 > 0:19:32- The forensics' team found - a piece of clothing in the forest.
0:19:33 > 0:19:36- Tests carried out on the fibres - were very revealing.
0:19:41 > 0:19:44- By examining the material...
0:19:44 > 0:19:48- ..they've discovered - it was dark green in colour...
0:19:49 > 0:19:52- ..and that it was a Pringle jumper.
0:19:52 > 0:19:56- By visiting - the Pringle company in Scotland...
0:19:56 > 0:19:59- ..we've recently ascertained...
0:20:00 > 0:20:05- ..that the jumper itself - was produced between 2000 and 2004.
0:20:05 > 0:20:08- That's very good news for us...
0:20:08 > 0:20:11- ..because we now know - that the body had been there...
0:20:12 > 0:20:14- ..after the year 2000.
0:20:14 > 0:20:18- Detectives hope someone - will recognize the jumper.
0:20:18 > 0:20:22- They're also awaiting DNA results...
0:20:22 > 0:20:26- ..hoping to trace - the man's family members...
0:20:26 > 0:20:28- ..on the National Database.
0:20:31 > 0:20:35- Studies on the teeth - that were discovered....
