SPOKANE, Wash. — A 17-year-old boy has pleaded guilty in the beating death of 88-year-old Delbert Belton, a World War II veteran who survived the battle of Okinawa but was killed in a robbery outside a Spokane bar in 2013.

Kenan Adams-Kinard pleaded guilty to first degree murder on Wednesday, in exchange for two lesser charges being dropped.

He faces a standard sentence to 20 to 27 years in prison when he is sentenced at a later date.

Adams-Kinard and Demetruis Glenn were both 16 when they were charged with severely beating Belton in his car on Aug. 21, 2013, during a robbery. The veteran died of his injuries the next day.

The two were scheduled to go on trial together next week. Glenn's trial is still scheduled to begin on Monday.
