Code Blue: Murder

The Murder of John “Jack” Williams


“Mum came running in, she didn’t even need to say anything, and she said it was my uncle Jack. And I just knew something wasn’t right. I knew he had gone and I don’t know why. At that moment I didn’t know what to feel - it didn’t feel real.” – Emma Williams, niece of John “Jack” Williams


This new two-part documentary series in ITV’s Crime and Punishment season tells the story of how detectives solved two vicious murders - from the first ‘Code Blue’ call to the crime scene, through to the convictions of the killers.


With extraordinary access to the multidisciplinary South Wales Police operation that brought the perpetrators to justice, Code Blue: Murder delves into the anatomy of murder investigations into the killings of Katherine Smith and John “Jack” Williams.


In the second programme, detectives are called out to an address in Swansea where the body of John Williams, known as Jack, has been found tied up with head injuries, apparently the victim of a brutal attack. The only potential motive officers can find is a substantial amount of cannabis scattered around the property - including what looks like a growing set-up in the attic.


The force’s head of major crime, Det Supt Richard Jones, tells his team: “There’s an awful lot to be done, it’s really about the detail to build this picture about his movements. I am sure the answer is out there somewhere. It’s a category A, it’s undetected and as things stand we’ve got no suspects.”


A neighbour provides a lead when she says a distinctively-dressed woman came to her door asking where Jack lived on the night he died. Then the woman is seen with two other men on another neighbour’s CCTV coming out of Jack’s house. 


When a detective recognises the woman, Gemma Owens, the police realise one of the men with her could be Jonathan Donne - who is well-known to them and has reportedly previously attacked cannabis cultivators in their homes.


Cameras follow as police track them down, and they arrest Owens, still wearing her distinctive coat. But Donne somehow escapes, and the hunt is on to find him. Officers hear Donne has a machete and may have been trying to get hold of a gun, and detective inspector Dean Llewellyn says: “There are firearms police in place now, if cornered he could come out potentially with weapons. Officer safety is paramount and public safety is paramount. We’ve got to get this dangerous individual off the streets.”


Simon Cairns, who owns the car in which Donne and Owens travelled to Jack’s house, is also arrested as the net closes in. Officers building the case against Donne prepare for a potentially dramatic takedown at a house where he has reportedly holed up on the outskirts of Swansea. 


Meanwhile, Jack’s family is left to reflect on his memory, and his brother David says: “He was my best friend, he was my confidant. The old saying is you don’t know what you’ve got ‘til it’s gone, and that’s very true. He’s always in my mind and in my heart.”


At trial, Donne was found guilty of murder and robbery and jailed for a minimum of 31 years. Owens and Cairns were acquitted of all charges.
