A TELLY detective has handed over evidence to Police Scotland, and the Crown Office which suggests serial killer Angus Sinclair could be responsible for unsolved murders in Glasgow.

Former cop Mark Williams-Thomas said yesterday he was sending a report to Scotland law authorities which sets out all the evidence against Glaswegian Sinclair.

He said: “My report will go to Police Scotland and the Crown Office setting out all the evidence against Angus Sinclair in relation to five murders, one child rape and one robbery which I believe is enough to prosecute him for.”

His report comes after the airing of his successful TV series The Investigator: A British Crime Story, which concluded on STV last night.

In the series, the former Surrey police officer analysed the unsolved murders of Anna Kenny, 20, Hilda McCauley, 36 and Agnes Cooney, 23 who were brutally abducted and killed within four months of each other in Glasgow in 1977.

Their killer has never been caught more than 40 years on but the show explored the possibility that Sinclair could be responsible.

Evil Sinclair was jailed for 37 years in 2014 for the murders of Christine Eadie, 17, and Helen Scott, 17, in Edinburgh in 1977.

The two teenage girls were abducted by Sinclair after meeting him in the World’s End pub.

He was initially tried and cleared of the killings in 2007 after a cold case review but in 2014 the introduction of the double jeopardy laws meant he was finally held to account.

He also serving another concurrent life tariff for the rape and murder of Glasgow teenager Mary Gallacher. The 17-year-old was found on waste ground in the Springburn area of the city in 1978.

Ex-cop Williams-Thomas said: “My investigation shows that the manner in which the Glasgow three were killed bears all the hallmarks of the World’s End murders in Edinburgh – for which Angus Sinclair was convicted.

“I can place Sinclair or his caravanette at all three Glasgow crime scenes, which means I believe Sinclair could be responsible for the abduction of the women.”

Anna Kenny, 20, disappeared after a night out with a friend at the the Hurdy Gurdy bar in Townhead in August, 1977.

She left with a man and he later revealed to police that she left him to get a taxi home.

She was missing for two years before her body was discovered in a shallow grave near Skipness on Kintyre.

In October 1977, the body of Hilda Miller, 36, was found covered by bushes at Langbank, near the M8 motorway.

The mum-of-two was last seen leaving the Plaza ballroom with a smartly dressed man.

Her body was discovered by kids out picking blackberries near a “lover’s lane”.

Two months later children’s nurse Agnes Cooney, 23, was found stabbed in woodland near Caldercruix, Lanarkshire. She had walked four miles from The Cladda Club in the South Side to an M8 sliproad and then hitched a lift to her home in Coatbridge.

Sinclair’s ex-wife Sarah also took part in her first ever TV interview for the show where she described him a “polite, kind and considerate” during their marriage

She also claimed the killer was responsible for “ten years of mayhem” killing women around Glasgow.

With her identity hidden, the “incredibly nervous and very private person” said she was speaking on air for the first time because she didn’t know why Sinclair “has never been charged with everything, everything that he has ever done”.

Sinclair was 25 when he married Sarah, then Hamilton, from Townhead in Glasgow in 1970. She was 20 and a trainee nurse.

They had met two years prior, just after Sinclair had served six years for the culpable homicide of his eight-year-old neighbour Catherine Reehill in Glasgow.

She said: “He was very polite, he was very kind, considerate. I was just really happy.”

Police Scotland said that they have been working with the production team behind the show.

A spokeswoman said: “Police Scotland has had ongoing engagement with the production team of ITV The Investigator as they have carried out research.

“ITV The Investigator has indicated that they may have new information, witnesses or evidence in these cases, therefore we have requested details of the new witnesses and accompanying evidence in order that we can fully explore these matters.”

A spokesman for the Crown Office added: “The Crown can only bring criminal proceedings where there is sufficient credible, reliable and admissible evidence in law to justify bringing a case to trial.

“As with all cases, we will carefully consider any new evidence that comes to light.”
