Code Blue: Murder

The Murder of Katherine Smith


“I saw three people coming towards us, and my words to them were, ‘Don’t say anything’s happened to her.’ And they just looked [at me]. And I just screamed the place down. I close my eyes and all I can see is Katherine trying to get to me.” – Katherine Smith’s mum, Debbie


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 two separate murder investigations, into the killings of Katherine Smith and of Jack Williams.


In the first programme, detectives are called out to a flat in Cardiff where the body of young mother Katherine Smith, aged 26, has been found on the floor with stab wounds. The key suspect is her boyfriend of six weeks, Anthony Lowe. Detectives know the first 48 hours is key in terms of gathering evidence and picking up suspects – but Lowe has gone missing.


Officers tracking Lowe’s mobile phone receive notification that it is ‘pinging’ off cell towers in the neighbouring police area around Bristol – and he is still sending text messages to Katherine’s family. Cameras follow as detectives race to Bristol to try to arrest him - as they pick up a text in which he threatens to commit suicide. But then he turns the phone off.


Senior investigating officer Det Chf Insp Rob Cronick says: “We desperately need to get answers from Lowe. With his phone now not responding and the fact he’s threatened to commit suicide, there’s a real chance we may be too late.”


He later turns up 30 miles away in Weston-Super-Mare and texts Katherine’s mum asking if her daughter is okay or not. The force’s head of major crime Det Supt Richard Jones says: “That would indicate he doesn’t know she’s dead, I mean he’s hoping then now by the look of it, that she’s possibly still alive. But previously he’s been saying he’s killed her. He’s been thinking about it, he’s more hopeful now that she might be alive, which is a way in, potentially, for negotiators.”


After a dramatic takedown outside a supermarket, Lowe is arrested and taken back to South Wales, where cameras follow as he is taken into custody. Now detectives need to build their case against him. In interview, Lowe submits a statement to detectives saying that after an argument Katherine had punched him and he had headbutted her, before he left the house. He denies stabbing her and says another person has keys to Katherine’s flat. Richard Jones says: “We believe and I still do, despite this, my working hypothesis is that he’s murdered her and left the scene at that time. And more importantly if he’s headbutted her to the face with such force that she’s fallen to the ground, there’s no corresponding injuries that would match on her face or nose.”


Detectives keep Lowe in custody while they build their case - making discoveries about him, like the fact he contacted a series of ex-girlfriends while on the run. One of them agrees to meet a detective and reveals a series of key personality traits about Lowe which help push the case on. The detective who goes to see the woman, named as ‘Jane’, says: “They met on which is a dating website, and with Tony Lowe, he presented himself as a 36-year-old when in reality he’s 46, he gave his name as Tony Moore when in fact his name is Anthony Lowe, he said he had interests in things that he didn’t have interests in and the persona that he gave was false. So when Katherine met him, she thought she was meeting somebody that wasn’t actually the person she was going to meet. And the person she did meet ended up murdering her.”


While Lowe clams up in the interview room, detectives discover a deleted video on his phone which provides direct evidence that they hope will put him behind bars for life.
