DNA samples taken from the clothing of Connor Gibson found “widespread blood staining” on the accused’s jacket, which experts said was compatible with 16-year-old Amber Gibson.

The 20-year-old is accused of assaulting and sexually assaulting his teenage sister, removing her clothes and repeatedly inflicting blunt force trauma to her head and body.

Her body was discovered on 28 November 2021 at Cadzow Glen in Hamilton, South Lanarkshire.

Alana Gunn, forensic biologist, told the trial at the High Court in Glasgow on Tuesday the blood found on the jacket, which was hanging in his room at the Blue Triangle hostel in Hamilton, also “appeared mixed with mud and dirt staining”.

Jurors heard how the DNA profile compatible with Amber was estimated to be “about one billion times more likely” to be from her than an unrelated individual.

Advocate depute Richard Goddard asked Ms Gunn: “There was widespread blood staining found on the front and both sleeves of the jacket?”

She said: “Yes, it was on a large area of the jacket.

“The DNA profile in other areas of the jacket which were examined could be explained by Amber Gibson as a major contributor and Connor Gibson as a minor contributor.”

The advocate depute asked: “That could be explained by Connor Gibson being involved in an assault of Amber Gibson?”

Ms Gunn replied: “Yes, it could be attributed that way. It is an overall interpretation given the blood staining as contact blood staining.”

A police scene at Cadzow Glen park in Hamilton where the body of Amber Gibson was discovered at around 10.10am on Sunday. The 16-year-old left her home in the Hillhouse area of Hamilton at around 9.15pm on Friday evening and was reported missing later that night after she did not return home.

Further blood stains were found on Gibson’s white and grey Adidas Gazelle trainers, which were found on the floor of his room.

The stains included a dropped spot of blood matching Amber’s DNA which could have come from an “open wound”, Ms Gunn said.

His DNA was also found on jogging bottoms and shorts, worn as underwear, which had been removed from the victim’s body.

Gibson is also alleged to have compressed the teen’s neck with his hands and strangled her with the intention to rape her.

He is further accused of attempting to defeat the ends of justice by disposing of blood-stained clothes, and calling the children’s home where his sister was living and pretending she was alive.

He also faces a charge of attempting to pervert the course of justice by telling police he had argued with his sister on the evening of 26 November before going to someone’s home.

A second man, Stephen Corrigan, 45, is also on trial.

He is accused of discovering Amber’s body between 26 and 28 November 2021 but instead of alerting police, he is alleged to have inappropriately touched her and concealed her body.

Both men deny all charges against them, with Corrigan’s defence agent Rhonda Anderson submitting a special defence of alibi on his behalf.

Jurors heard that Corrigan’s DNA on the victim was “widespread” and included 39 areas of her body, including her buttocks, breasts and pubic area.

Ms Gunn told the court: “In our opinion, based on the collective findings relating to Stephen Corrigan, it could be explained if he had direct contact with Amber Gibson while she was unclothed.”

She also said the evidence did not suggest that Ms Gibson had redressed after Corrigan’s DNA had been on her body, and added that the presence of his DNA could “not be explained by the statement that he had never had any contact with Amber Gibson”.

The trial, before Lord Mulholland, continues.
