Clallam County prosecutors have added charges of attempted murder against a Sequim-area boy accused of plotting to kill three football coaches and leading deputies and troopers on a high-speed highway chase.

Court records filed this week in Clallam County juvenile court allege that the 14-year-old boy planned to kill three Sequim High School football coaches as retribution for punishment the coaches imposed on the boy at a football camp last summer.

Deputy Prosecuting Attorney Kristin Ballinger on Wednesday amended the charges against the boy to include three counts of first-degree attempted murder for plotting against varsity coaches Erik Wiker and Brad Moore and junior varsity coach Isaac Rapelje, who are named in charging papers.

The boy, who does not attend Sequim High, is also charged with first-degree robbery, second-degree assault, second-degree unlawful possession of a firearm and second-degree taking a motor vehicle without permission, all felonies.

Held on $1 million bond

He is being held at the county juvenile detention facility in lieu of an amended bail amount of $100,000 cash or $1 million bond, set by Court Commissioner William Knebes.

The Peninsula Daily News does not report the names of people charged as juveniles.

Ballinger has moved for a hearing to determine whether the boy should be tried as an adult.

The boy was arrested Oct. 30 after leading law enforcement officers on a high-speed chase on U.S. Highway 101 and state Highway 104 in three counties, crashing into three vehicles and aiming a shotgun at a state trooper at the east end of the Hood Canal bridge.

Court records indicate the boy had dressed in camouflage clothing and facepaint earlier that day, pointed a loaded shotgun at his stepmother and demanded her car keys, then drove her minivan from his home to the high school bus barn, arriving about two hours after the high school football team had departed for a game in Tacoma.
