The partner of murdered single mum Claire Turnbull has angrily refuted suggestions that she made sexual advances towards another woman shortly before she was killed.

Charles ‘Chick’ Weir, 39, told a jury there was no truth in claims that she had given a “sexual kiss” to 30-year-old Laura McMurdo, one of the people accused of her murder.

He also rejected defence suggestions that Claire, 36, was “making advances” towards the other accused Aaron Donald, 28, during a drink-fuelled house party in Donald’s flat in Blairhall on the day she died.

Mr Weir told the jury he had left the flat and gone home because he was feeling unwell, not because he had argued with his partner about her behaviour towards the others.

Claire was found lying dead in a pool of blood and with serious head injuries in the livingroom of the property in Rintoul Avenue on October 5 2018.

Donald and McMurdo, whose addresses were given as Blairhall, deny murdering her and attempting to defeat the ends of justice by lying to police and hiding a hammer believed to be the murder weapon.

Donald has lodged two special defences claiming he was suffering from a mental disorder and from diminished responsibility at the time of the alleged killing.

Giving evidence on the second day of the pair’s trial at the High Court in Livingston, Mr Weir denied seeing any “intimate behaviour” between Claire and McMurdo when the two accused bought a large carry-out at Tesco’s in Dunfermline.

He agreed that video of the two women at Dunfermline bus station showed them hugging and smiling at each other.

But asked if Claire had been “making sexual advances” towards McMurdo, he replied: “That didn’t happen. She never done that.”

Advocate depute Bernard Eblett asked him: “If it was suggested that Aaron Donald asked you to tell Claire to stop doing that, did that happen?” He replied: “Not that I can remember. No.”

Mr Eblett said: “If it was suggested to you that Claire was making sexual advances towards Laura, and Aaron asked you to tell Claire to make it stop, did that happen?” He replied: “No The only thing that happened was him (Aaron) pulling down her (Laura’s) top.”

Mr Eblett went on: “Outside Tesco’s did you see any intimate behaviour by Claire Turnbull on Miss McMurdo?” He answered: “No.”

Under cross examination by Donald’s defence counsel Bert Kerrigan QC, Mr Weir said he had not seen what a casual shopper at Tesco’s might tell the jury was “a sexual kiss” by Claire.

He said: “I didn’t see that, but Claire was friendly. She’d cuddle you. If she had a drink in her she was friendly, she was friendly to everybody.”

Mr Weir insisted he had never seen Claire kissing other females.

In Donald’s house he said he thought Claire and McMurdo had been “getting on fine”.

Asked if she had been cuddling the female accused he said: “As I say, Claire was a friendly person. She was cuddling me. You’re making her out to be someone she’s no.”

Mr Kerrigan asked if there was a point where McMurdo made it perfectly clear this was not welcome, he replied: “Aye, so she died for that. She could have asked her to leave the house. The answer’s no.”

Mr Kerrigan persisted: “Wasn’t it the case that Miss Turnbull was also making advances towards Aaron Donald which he was telling her weren’t welcome? Wasn’t he telling her to behave herself?”

Mr Weir answered: “No. If that was the case why didn’t he kick her out of the house instead of murdering her?”

Dr John Patrick, 43, a consultant forensic psychiatrist and psychotherapist at the State Hospital, Carstairs, assessed Donald after the accused was admitted on March 19 this year.

He said Donald had told him that Claire was “very flirtatious” with McMurdo in his flat.

The doctor added: “He said: ‘It wouldn’t bother me because I didn’t see it as cheating on me if she was with a woman.’ He stressed he definitely wasn’t jealous.

“Donald gave a reasonable account of the alleged offence. From his account it was clear that there was no evidence of psychiatric illness in the days and weeks leading up to it nor during the actual offences themselves.”

He revealed that Donald had alleged he’d been sexually assaulted by a number of people and forced to commit sexual acts. Donald claimed he was given roll-ups containing legal highs, had a noose placed round his neck and was asked to sign a suicide letter.

Dr Patrick agreed that was the sort of incident that could cause Post Traumatic Stress Disorder.

However, he added: “It is very unlikely he was suffering from PTSD during the incident with Claire and the use of a hammer as suggested by another expert.

“It may be delusional belief, legal highs may have led to a psychotic episode.”

Under cross examination by Mr Kerrigan, the consultant said that Donald had given him an account saying he had pulled Claire off his co-accused and grabbed a hammer that was sitting beside him and “hit her a few times” and that “it all happened very quickly”.

The court heard that Donald had told the psychiatrist: “I always have a hammer with me” in response to a number of occasions when he’d been sitting in his room and people had run in to assault him.

He also said he had not phoned an ambulance but seemed well aware what had happened was wrong and that he would be in trouble for this.

The trial, before judge Lady Scott, continues.
