0:03:46 > 0:03:49- He'd been to the farmhouse before.
0:03:49 > 0:03:53- A crime was committed here - six years previously...
0:03:53 > 0:03:56- ..in which a gun was stolen.
0:03:56 > 0:03:59- The individual under suspicion...
0:03:59 > 0:04:02- ..had a tendency to - return to places he'd been before.
0:04:03 > 0:04:07- Straightaway, - Gambrell became the prime suspect.
0:04:09 > 0:04:12- Richard Anthony Gambrell - came from Hampshire.
0:04:12 > 0:04:16- He found work in the area - as a shepherd in the late '70s.
0:04:16 > 0:04:19- He soon - came to the police's attention...
0:04:19 > 0:04:23- ..when he stole a two-barrel shotgun - from Brynambor farm...
0:04:23 > 0:04:27- ..and when he held two pensioners - hostage in Rhandirmwyn.
0:04:30 > 0:04:32- He came back time and time again.
0:04:33 > 0:04:37- I don't know why but he'd developed - a kind of obsession with the area.
0:04:42 > 0:04:46- Armed police came to Llanddewi Brefi - to hunt for Gambrell.
0:04:46 > 0:04:49- If he was the culprit...
0:04:50 > 0:04:52- ..it was feared he might kill again.
0:04:56 > 0:04:58- As an 18-year-old young man...
0:04:58 > 0:05:02- ..Emyr Lake was among those - who helped in the manhunt.
0:05:07 > 0:05:11- It was feared that Gambrell - was loose on the mountain...
0:05:11 > 0:05:13- ..in possession of a gun.
0:05:18 > 0:05:20- People were in a panic.
0:05:21 > 0:05:24- Police made regular calls - to every farm.
0:05:24 > 0:05:29- Residents had a secret code - to confirm everyone was safe.
0:05:30 > 0:05:33- Two policewomen phoned the farms...
0:05:33 > 0:05:36- ..every half an hour or hour.
0:05:37 > 0:05:40- As long as everyone gave the code, - it was fine.
0:05:40 > 0:05:45- If there was no answer, armed - police were sent to the farms...
0:05:45 > 0:05:50- ..to make sure residents were safe - and everything was OK.
0:05:51 > 0:05:55- But the fear was too much - for some families on the mountain.
0:05:58 > 0:06:02- Many families have moved out - of their mountain homes.
0:06:03 > 0:06:07- 12 farmers have left their homes - between Llanddewi and Rhandirmwyn.
0:06:13 > 0:06:17- Soon, it emerged - that Richard Anthony Gambrell...
0:06:17 > 0:06:20- ..had fled over the hills - to Llanwrtyd Wells.
0:06:21 > 0:06:25- He'd been staying in a hotel - under a false name to evade capture.
0:06:28 > 0:06:31- Police found - his fingerprints there...
0:06:31 > 0:06:33- ..and in a nearby phone kiosk.
0:06:33 > 0:06:37- These fingerprints - were key to the investigation.
0:06:44 > 0:06:49- For decades, fingerprints - have been vital in crime detection.
0:06:49 > 0:06:53- I visited the - North Wales Police's laboratory...
0:06:54 > 0:06:56- ..to discover - how they analyse fingerprints.
0:06:57 > 0:07:01- We have items - recovered from crime scenes here.
0:07:02 > 0:07:05- We're going to treat them - with a chemical called Ninhydrin.
0:07:05 > 0:07:10- It reacts with the amino acids...
0:07:10 > 0:07:12- ..from the fingerprints.
0:07:14 > 0:07:17- When we've examined - and marked up the fingerprints...
0:07:18 > 0:07:22- ..we take photographs - to be used as evidence.
0:07:22 > 0:07:28- The next step is to put these items - in the oven for six minutes...
0:07:29 > 0:07:31- ..for them to develop in the heat.
0:07:33 > 0:07:37- The police's ability to collect - fingerprints has evolved.
0:07:38 > 0:07:40- Sophisticated techniques - are now used.
0:07:41 > 0:07:45- This is a superglue cabinet, - and with non-porous items...
0:07:45 > 0:07:47- ..we put them in this cabinet...
0:07:48 > 0:07:52- ..and put superglue - in this small foil tray.
0:07:53 > 0:07:57- It heats up and the superglue - evaporates in the cabinet...
0:07:58 > 0:08:01- ..and then it reacts - with the fingerprints...
0:08:01 > 0:08:04- ..to create white fingerprints.
0:08:06 > 0:08:09- This torch - was left at the crime scene...
0:08:10 > 0:08:14- ..so we want to see - if there are fingerprints on it.
0:08:14 > 0:08:19- We're checking the batteries for - fingerprints as well as the torch.
0:08:22 > 0:08:24- MACHINE BEEPS
0:08:30 > 0:08:32- Here are the items.
0:08:35 > 0:08:41- These techniques weren't available - to Dyfed-Powys Police in the '80s.
0:08:45 > 0:08:47- But the fingerprints...
0:08:47 > 0:08:50- ..Gambrell left - at Brynambor and Llanwrtyd...
0:08:50 > 0:08:53- ..were enough - to lead detectives to the killer.
0:08:54 > 0:08:56- But they were too late.
0:08:56 > 0:09:00- Gambrell had fled by train - from Llandrindod Wells to England.
0:09:06 > 0:09:11- In Hampshire, he contacted a former - schoolteacher to arrange a meeting.
0:09:11 > 0:09:15- But he, in turn, - phoned the police...
0:09:15 > 0:09:18- ..and Richard Anthony Gambrell - was arrested...
0:09:18 > 0:09:21- ..and transported back to Wales.
0:09:22 > 0:09:24- Gambrell pleaded - not guilty to the murder.
0:09:25 > 0:09:29- He claimed he'd gone to Brynambor - to shelter, thinking it was empty...
0:09:30 > 0:09:33- ..and shot John Williams - in self-defence.
0:09:36 > 0:09:40- But the local residents - didn't believe him.
0:09:40 > 0:09:44- Outside the court in Lampeter, - a crowd of people...
0:09:44 > 0:09:48- ..wanted justice - for John Williams and his family.

0:10:46 > 0:10:51- ..there were five wardens his side - of the table to keep him in line.
0:10:51 > 0:10:54- The first thing he said to me was, - "I know you."
0:10:55 > 0:10:58- I'd escorted him - into custody back in '77.
0:10:59 > 0:11:01- He'd promised - to tell John's sister...
0:11:02 > 0:11:04- ..the whereabouts - of the money and gun.

0:11:12 > 0:11:17- ..Gambrell has sent letters to - the area's residents from his cell.
0:11:18 > 0:11:22- Are you worried that Gambrell - might be released one day?

0:11:26 > 0:11:29- When he's released, - he might return to the gun.
0:11:29 > 0:11:31- Who knows if he'll come back?
0:11:33 > 0:11:39- It is a worry, but hopefully he'll - spend the rest of his life in jail.
0:11:39 > 0:11:41- If Gambrell is ever released...
