A 15-year-old student on Tuesday admitted stealing his father’s combination rifle/shotgun and bringing it to Evergreen High School with plans to sell it to another student.
Wyatt Michael Ball of Vancouver pleaded guilty to possessing a dangerous weapon at school and theft of a firearm.
He will return to court Dec. 31 for sentencing.
The presence of the rifle, with an interchangeable barrel that enables it to also function as a shotgun, prompted the evacuation of the high school Dec. 12 and a premature end to classes. Four other schools were locked down.
Ball was arrested and expelled from school after a teacher found the weapon inside a black nylon case under a table in his classroom and reported it to authorities.
Police identified the weapon as a single-shot Rossi .410 gauge, .22 caliber rifle/shotgun. The case contained the rifle and ammunition. The barrel was detached from the weapon, which needs to be assembled to fire.
No one was threatened with the weapon, police said.
Ball indicated to detectives that he planned to sell the weapon to another student in exchange for $40 and an iPod Touch, according to police.
