Teenagers accused of murder 'hugged and shook hands' after attack

Teenagers accused of murdering a 16-year-old at Irvine Beach were seen "cuddling" and shaking hands after the fatal stabbing, jurors have been told.

A 15-year-old boy and Jay Stewart, 18, are accused of killing Kayden Moy on 17 May 2025. Cole Turley, 18, pleaded guilty to the murder before the trial started at the High Court in Glasgow.

Jurors were taken through a number of CCTV and mobile phone clips of the entire incident in consecutive order, including footage of Turley hugging the 15-year-old and shaking hands with Stewart.

Forensic biologist Claire Vallance earlier told the court only Turley and Moy's DNA was found on the murder weapon, a lock back knife.

The trial previously heard that Turley, Stewart and the 15-year-old were part of the Murray Boys gang in East Kilbride, South Lanarkshire.

Moy and his friends were stated to be members of the rival Himshie gang, and an altercation between the groups occurred at the beach.

Initial clips shown in court included Moy and his friends arriving at Irvine train station, as well as the other trio arriving separately.

Turley and the 15-year-old were stated to have put their hoods up after getting off the train, before meeting up with two other youths and going to the beach.

Various mobile phone clips of the incident previously played to the court as well as the aftermath of the stabbing were shown to the jury.

Previously unseen footage was then played of the trio, who appeared to be running down a road near the beach.

Jurors were told Stewart and Turley were seen to be "shaking hands."

In a later part of the footage, prosecutor Liam Ewing KC asked witness Brian Hamilton - a detective constable with the police - what he could see.

Det Con Hamilton replied: "One hand coming out from the 15-year-old boy and one from Turley."

Ewing said asked if the handshake being completed was visible and Hamilton said no.

In later footage, Ewing asked Hamilton who was cuddling, with the witness saying it was the 15-year-old and Turley.

They then appeared to be clapping hands.

Donald Findlay KC, defending Stewart, put it to Hamilton that his client had in no way tried to disguise himself and the witness replied: "No."

In regard to footage of the aftermath of the incident, Findlay put it to the witness that there were people closer to Moy than Stewart was, which Hamilton agreed was possible.

Earlier Findlay KC, defending Stewart, had asked what conclusion Vallance had made in regards to the weapon.

She replied: "There was no DNA attributed to Jay Stewart on this knife."

Findlay then asked if this was consistent with Stewart never having handled the knife in his life, to which the witness replied yes.

The advocate also asked Vallance if she could say whether deposits of Stewart's DNA found on an extendable baton were deposited at the same time.

Findlay said: "Is the answer 'I don't know'?" and Vallance replied that was correct.

Ian Duguid KC, defending the 15-year-old, put a scenario to the witness where the murder weapon was passed from the waistband of his client to Turley to commit the murder.

The advocate said: "The knife in its entirety had nothing at all which can be identified from the boy?"

Vallance replied: "That's correct."

The trial continues before Judge Lord Scott.
