VANCOUVER, Wash. (AP) – A 16-year-old boy charged in the death of a young man during a drug robbery north of Vancouver will serve time in a juvenile facility until he turns 21.

The Columbian reports the teen pleaded guilty Tuesday to first-degree murder in Clark County Juvenile Court in the shooting of 18-year-old Gage Kiser of Vancouver.

Court documents say three boys planned to rob Kiser of marijuana Dec. 10.

Prosecutors say a 17-year-old boy shot Kiser multiple times. The 17-year-old is awaiting a hearing to determine whether his case will be moved to adult court.

A 15-year-old was convicted of robbery and sentenced to some three to six years in a juvenile facility.

The 16-year-old sentenced Tuesday said in a written statement that he took a plea deal to avoid the possibility of his case being moved to adult court.
