Jury 'urged to convict' two teens of murdering Kayden Moy at beach

A jury has been urged to convict two teenagers of murdering a 16-year-old boy on Irvine Beach.

The 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.

The charge says Stewart and the 15-year-old, while acting with Turley pursued Kayden and caused him to fall to the ground before they repeatedly stabbed him to the body.

It is alleged that Stewart and the other teenager had previous ill-will and malice towards him.

The trial had previously heard that Turley, Stewart and the 15-year-old were part of The Murray Boys gang of East Kilbride, South Lanarkshire. Kayden and his friends were stated to be members of the rival Himshie gang.

Prosecutor Liam Ewing KC spoke to jurors on Tuesday in his closing speech and outlined both teenagers’ involvement in the murder.

Mr Ewing stated that Stewart had previously threatened Kayden with violence prior to the attack on social media.

The advocate depute said that Stewart and the 15-year-old travelled together to the beach with Turley having heard that a 17-year-old associate had been in a fight with a member of Kayden’s group earlier that day.

Mr Ewing said: “Stewart took with him a weapon – not a knife but a baton which can inflict serious injury.”

It was stated that Stewart and the 15-year-old shouted and threw rocks at Kayden’s group of friends.

Mr Ewing added: “The rocks don’t appear to have struck anyone – it was an exercise to flush out the Himshie group to invoke a reaction and it did so.”

Amid the confrontation between the two groups, Stewart was stated to be “jumping back and forward” and was “ready for a fight.”

Mr Ewing claimed that footage of the incident showed Stewart and the 15-year-old “moving forward.”

Stewart is claimed to have looked at Kayden “aggressively” after the stabbing by Turley and said: “He f***ing deserves it.”

Mr Ewing referred to footage of the trio running down a road minutes after the attack.

The advocate depute said: “They were shaking hands with Cole Turley.

“The 15-year-old cuddles or embraces Cole Turley moments after he stabbed Mr Moy.”

It was stated that the three teenagers then took a taxi from a property in Irvine back to East Kilbride before entering the home of a 19-year-old who was “friendly” with Turley.

Mr Ewing claimed that the duo on trial, as well as Turley, asked the 19-year-old, “Is he dead?” in reference to Kayden.

The advocate depute said that on receiving information Kayden was still alive at the time, a song was made up about him.

Jurors heard the lyrics included “Kayden bop” as Stewart and the 15-year-old touched their stomach and leg. Reference was also made to Kayden being “cheffed up.”

Addressing the 15-year-old specifically, Mr Ewing stated to jurors that he put his hood up upon leaving the train on foot for the beach.

It was stated that the 15-year-old had also asked his associate who had previously been attacked: “Do you want to see a fight?”

Mr Ewing also touched on evidence that the 19-year-old was told by the 15-year-old that he passed the lock-back knife murder weapon to Turley before the stabbing.

Jurors had previously heard that no identifiable trace of the 15-year-old’s DNA had been found on the knife when analysed.

Mr Ewing told jurors: “Why did they travel to that place at that time and with weapons?

“The two boys and Cole Turley went for the purposes of retaliation or retribution for that [earlier] incident.

“You should conclude that they went to engage in a violent confrontation with that group.”

Mr Ewing went on to claim that the trio’s actions “were the actions of people who did what they came to do.”

The advocate depute stated that the duo on trial acted in concert with Turley in committing the murder.

He added: “There is credible and reliable evidence which shows this.

“That evidence establishes that there was a common criminal purpose and there was scope in the use of violence to cause serious injury and with that carried an obvious risk to life.

“Therefore, I invite you to convict both accused of murder.”

Mr Ewing had previously withdrawn all charges other than the murder allegation against the duo at the close of the Crown case.

Donald Findlay KC, defending Stewart, and Ian Duguid KC, defending the 15-year-old, will give their speeches to the jury on Wednesday.

The trial continues before Judge Lord Scott.
