A TEENAGE killer stabbed a young man in the heart during a row.

Steven Gilmour was just 17 when he fatally attacked Daryll Wright at a house in Kilwinning on May 22, 2021.

Daryll, 20, of Coatbridge, never recovered and passed away in hospital.

Gilmour - now 18 - today (December 16) faced a murder charge at the High Court in Glasgow.

But, the first offender - via his KC Donald Findlay - pled guilty to the reduced charge of culpable homicide, which was accepted by prosecutors.

Gilmour was remanded in custody and will learn his fate in the New Year.

The hearing was told a number of young men and women had gathered at the house in Kilwinning.

Gilmour had turned up uninvited but was allowed in.

Gilmour later ended up getting into a fight with Darryl which also saw the victim being hit with a stool and a bike hurled towards him.

Prosecution solicitor Miss Leanne Cross explained: "Both ended up on the floor. After being on the floor, Gilmour was seen to get up and back away.

"It was seen that he had a knife in his hand."

Gilmour dropped the weapon and fled the scene. 

Daryll was also initially able to get up and went outside before collapsing in an alleyway.

The victim was described as being in a "bad way". A girl was heard screaming as she raced to help him.

Miss Cross added: "He begged her not to let him die and to call 999."

Daryll was rushed to Crosshouse Hospital in Kilmarnock.

He had a stab wound to the chest and to his inner left thigh.

The young man went on to suffer a heart attack and ended up in intensive care.

He never recovered and passed away on May 24.

The fatal wound had penetrated the front of Daryll's heart.

The court heard Gilmour had initially fled to his own home nearby in Kilwinning.

He went on to message a girl on Snapchat and admitted he had been "fighting" with Daryll.

Miss Cross said: "He said he did not mean to do it, but had picked up a knife as a threat.

"He said that he felt horrible, hoped (Daryll) would pull through and that it was all a mistake."

Gilmour was later charged with murder and bailed by a sheriff.

But he ended up behind bars amid claims he then assaulted another man in Kilwinning and brandished a blade at him on New Year's Day 2022.

Gilmour had also faced those charges today, but prosecutors accepted his not guilty plea.

He appeared from custody to admit killing Daryll, who is survived by his partner, mother as well as a half brother and sister.

Lady Stacey remanded Gilmour and deferred sentencing for reports.
