A TEENAGER has been jailed for at least 15 years for the murder of a 17-year-old by stabbing him in the back.

Steven McIntyre, 19, killed Jack Doyle, of Rose Street, Greenock, on January 3, in the town's Antigua Street.

The court heard that the single stab wound went through Jack's liver and severed two main blood vessels and he bled to death. Callous McIntyre was playing with his X-box just hours after Jack died.

Yesterday at the High Court in Glasgow temporary judge Sean Murphy QC told Steven McIntyre: "There is no suggestion you armed yourself or set out looking for trouble.

"That night it was Jack Doyle who was showing a knife to others. You chased Jack Doyle and then stabbed him."

Co-accused Kevin McIntyre, 28, who had admitted slashing Jack on the face just minutes before he was murdered was jailed for five years and six months. Judge Murphy said: "He would have been disfigured for life."

Kevin McIntyre's defence QC Brian McConnachie said his client was remorseful.

As the sentences were passed members of Jack Doyle's family shouted they were a "joke".

This is the second time tragedy has struck the Doyle family. Jack's aunt Elaine Doyle was just 16 when she was murdered in 1986.

Defence QC Derek Ogg said Steven McIntyre maintained he acted in self-defence.
