A man accused of inappropriately touching a dead teenage girl was allegedly at his father's home at night over the weekend he is claimed to have committed the crime.

The elderly dad of Stephen Corrigan told jurors his 45-year-old son was living with him between November 26 and 28, 2021.

It is said on an occasion between those dates Corrigan committed a breach of the peace and attempted to defeat the ends of justice.

It is claimed Corrigan found 16-year-old Amber Gibson's body at Cadzow Glen in Hamilton.

But, rather than alert police, he allegedly inappropriately touched her and then hid her remains under bushes and branches.

He has lodged a special defence of alibi.

Amber's brother Connor Gibson joins him in the dock at the High Court in Glasgow, where the 20-year-old is accused of the sexual assault and murder of the teenager at Cadzow Glen, on Friday, November 26 2021.

Neither Gibson or Corrigan gave evidence as prosecutors closed the Crown case on Thursday.

Instead, the latter's legal team called his 79-year-old father William Corrigan to testify.

The retired baker told how he took his son to get a covid jab on November 26.

Corrigan was said to already have an arm in a sling following an earlier fall.

After returning from having the jag, the OAP said his son asked to stay at his as he was "sore" and "did not feel like going home".

William told Rhonda Anderson, defending, that Corrigan stayed overnight.

The next morning, the witness told jurors he made breakfast for his son and grandson.

William then visited his local pub and bookmakers that afternoon.

When he returned, he believed Corrigan and his grandson were not initially in.

He fell asleep, but, by the time he awoke, he said they were back and later had dinner together.

Under cross-examination, William initially stated he did not know what happened after they ate on the Saturday.

But, he later claimed Corrigan ended up in bed that evening and in "agony".

Prosecutor Richard Goddard KC put to him: "Why do you remember him lying in bed now?"

The witness said: "I am not making up stories."

He insisted he did not "lie" adding: "I speak the truth."

Questioned again later by Miss Anderson, the OAP agreed that he would have been "aware of noises" had someone left his home.

The lawyer put to him that his son had been staying with him over that weekend.

Miss Anderson went on: "Did he ever leave your house at night-time?"

William said: "No."

The witness was earlier quizzed on his son's knowledge of Cadzow Glen.

William said Corrigan "went through it often enough", but added he did not know how many times.

Mr Goddard asked: "Did Stephen go for walks in Cadzow Glen?"

He replied: "Probably did. I have never been for walks there. He did because he does not have a car."

The trial, before judge Lord Mulholland, continues.
