WACO, Texas (AP) - A 13-year-old boy who admitted stabbing a teenage friend to death earlier this summer received a 15-year sentence today in a plea agreement.

State District Judge Alan Mayfield accepted the plea agreement after rejecting a 10-year proposal earlier this month.

The Waco Tribune-Herald County reports the youth pleaded "true" to the first-degree murder charge.

Officials say the former Provident Heights Elementary School student is the youngest person in McLennan County charged in a murder.

Authorities said the boy, whose name isn't being released because of his age, stabbed 14-year-old Keith Dancer in the heart with a steak knife during a dispute.

Officials say he was 12 at the time of the June sixth stabbing.

The boy's mother, Babette Wilkerson, has said her son was attracted to the older boy and was upset that his feelings were not reciprocated.
