THE man accused of murdering Claire Turnbull in Blairhall last year made a dramatic confession in an interview with police detectives, a court heard today.

In a video shown to the jury at the High Court in Livingston, Aaron Donald told how he grabbed the 36-year-old by the throat because she was “inappropriately” grabbing his girlfriend, co-accused Laura McMurdo, following a booze session.

The footage was from a police interview with Donald at Dunfermline Police Station the day after the killing at McMurdo’s flat in Blairhall, on October 5 last year.

Donald, 28, who appeared agitated and distressed throughout the video interview, blurted out that he had been sexually abused and had had psychiatric problems before coming out with the full confession.

He told officers: “That lassie was constantly getting on top of Laura on the floor, Laura was actually on her back, this lassie was on top of her trying to kiss her and everything.

“Chick (Weir, Claire’s partner) he got that sick of trying to stop her doing it that he f****** left.

“I wish he’d taken her with him but he didnae. He said: ‘I’ve had enough. F**k this. I’m off!’”

In the interview, Donald went on: “Laura made it clear it was unwanted, very clear. She said: ‘Aaron, help me. Get her off me!’

“I just remember grabbing her by the throat and I punched her like twice or something. She was f****** laughing.

“When I hit her she was laughing. I grabbed a hammer and I hit her with it.

“I didn’t try to kill her and didn’t mean to kill her, I just didn’t want her to be able to do that to Laura or anybody else again.

“I just wanted to stop what was happening to Laura. That’s all I wanted. 

"I couldn’t believe what had happened. It was all very quick.”

He claimed his girlfriend Laura wasn’t even in the room at the time of the murderous attack.

He added: “I was sitting looking at this f***** lassie and I couldn’t believe what I was seeing.

“I says to Laura: ‘Gie’s your phone, and I took a couple of pictures of this lassie – and the reason for me doing that was for when I went back to my dad to show him that I wasn’t kidding on. It wasn’t for any other reason. It was on Laura’s phone.

“I phoned my boss and I said something along the lines of: ‘I think I’ve killed somebody’ and that’s all I can remember saying.

“I just didn’t like what she was doing to my girlfriend. I didn’t mean to murder her. I didn’t mean it.

“I understand what I did. I’ve ruined my life. My whole life’s over. I’ve got children.

“That lassie – even though she was a f****** a*******, she’s got family too and I’m sorry, sorry.

“Please understand, my girlfriend she had nae part in it whatsoever. Nae part.”

Donald and McMurdo, 30, both from Blairhall, are accused of murdering Claire at a flat in Blairhall and attempting to defeat the ends of justice by hiding a hammer believed to be the murder weapon and giving police false information.

They deny the charges and Donald has lodged special defences claiming he could not be held criminally responsible because he was suffering from a mental disorder and diminished responsibility at the time of the killing.

Earlier the jury heard Scott Livingston, 38, telling how he listened to a telephone confession from Donald on his former boss’ mobile phone.

The boss, panel beater Paul Smith, had given evidence to the court on Friday. 

Mr Livingston said: “Paul asked him what he had done and he said he had hit her eight or nine times with a hammer.

“He sounded like he was talking total calm. I didn’t know what to do.

“Paul was asking him questions, he was giving answers. I heard him say: ‘There's brain matter. She’s dead.’

“I thought, it cannae be real. I just didn’t understand how it could be real. It just didn’t sound human.”

Police witnesses revealed that a bloodstained hammer had been recovered from a bag the accused had with them at a bus stop, near the flat where Claire was found dead.

The trial, before judge Lady Scott, continues.
