NEW YORK (AP) _ A teenager who was part of a gang that fatally stabbed a 15-year-old boy over an iPod was convicted Tuesday of murder.

Brooklyn prosecutor Charles Hynes said a jury deliberated for three hours before convicting Darren Samuel, 17, of robbery and second-degree murder in the July attack. He faces as many as 25 years in prison.

The victim, Christopher Rose, was stabbed in the chest when he and friends resisted a group that accosted them in the street and demanded they give up an iPod one of them was carrying.

During his trial, Samuel admitted being with the group that robbed Rose, but said he ``froze'' when the mugging began and did not participate in the attack. He blamed the stabbing on his 20-year-old cousin, Aaron Farrell, who is to be tried on murder charges next month.

An 18-year-old defendant is awaiting trial on a charge of hindering prosecution. A fourth person, Quaison Fraser, 18, pleaded guilty to gang assault and is expected to be sentenced to 3 1/2 years in prison.
