TEENAGERS accused of murdering a 16-year-old at Irvine Beach were seen "cuddling" and "handshaking" after the fatal stabbing, jurors heard today.
A 15-year-old boy and co-accused Jay Stewart, 18, are accused of killing Kayden Moy on May 17, 2025.
Cole Turley, 18, pleaded guilty to the murder before the trial started at the High Court in Glasgow.
Jurors on Monday were taken through a number of CCTV and mobile clips of the entire incident in a consecutive order with 42-year-old witness, detective constable Brian Hamilton.
Initial clips showed Mr Moy and friends, as well as the trio, arriving separately at Irvine railway station. Turley and the 15-year-old were stated to have put their hoods up after getting off the train.
The footage shows the trio meeting up with two other youths before they headed to the beach.
Various mobile phone clips of the incident previously played to the court, as well as the aftermath, were shown to the jury. Previously unseen footage was then played of the trio, who appeared to be running down a road near to 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 the witness what he could see. DC Hamilton replied: “One hand coming out from the 15-year-old boy and one from Turley.”
Mr Ewing said: “We don’t see whether the handshake is completed?”
DC Hamilton said: “No.”
In later footage, Mr Ewing asked DC Hamilton who was “cuddling".
The witness replied: “The 15-year-old boy and Turley.”
Mr Ewing asked: “What is happening now?”
DC Hamilton answered: “It looks like Turley has his arms around the 15-year-old boy.”
As the footage went on, Mr Ewing asked: “What does it look like there?”
DC Hamilton replied: “It looks like the clap of the hands.”
Donald Findlay KC, defending Stewart, put it to DC Hamilton that his client “in no way” tried to disguise himself and the witness replied: “No.”
In regard to footage of the aftermath of the incident, Mr Findlay put it to the witness that there were people closer to Mr Moy than Stewart was, and he replied: “It’s possible.”
Mr Findlay referenced handshaking and asked if the best person to explain why Turley was offering a handshake would be Turley himself, to which DC Hamilton replied: “Yes.”
Jurors earlier heard a second day of evidence from a forensic biologist who described items of note seized as part of the investigation into the killing. This included a lock-back knife, which the court had heard was the murder weapon.
Claire Vallance previously told the court that only Turley and Mr Moy’s DNA was found on the knife. In cross examination Mr Findlay asked what conclusion "scientifically" Miss Vallance made in regards to the "murder weapon".
She replied: "There was no DNA attributed to Jay Stewart on this knife."
Mr Findlay: "This is consistent with Jay Stewart never having handled that knife in his life?"
Miss Vallance said: "Yes."
The advocate also asked Miss Vallance if she could say whether deposits of Stewart's DNA found on an extendable baton were deposited at the same time. Mr Findlay said: "Is the answer 'I don't know'"?
Miss Vallance replied: "Yes."
Ian Duguid KC, defending the 15-year-old, put a scenario of the knife murder weapon being 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?"
Miss Vallance said: "That's correct."
The trial continues before Judge Lord Scott.
