(Reuters) – A Washington state teenager changed his plea to guilty on Wednesday in the murder of a World War Two veteran he beat up with an accomplice in 2013 during what he said was a drug deal, Spokane area media reported.

Kenan Adams-Kinard, 17, pleaded guilty in Spokane County Superior Court to first-degree murder in the death of 88-year-old Delbert “Shorty” Belton, as a part of a deal in which robbery charges against him would be dropped. He could serve between 20 and 27 years in jail on sentencing, according to media reports.

Belton, who had survived a gunshot wound to the leg during the Battle of Okinawa in 1945, died a day after being beaten up in August 2013 by Adams-Kinard and his accused accomplice, Demetrius Glenn, both 16 at the time, outside a Spokane area fraternal lodge.
