An 18-year-old accused of bringing a gun to Central Valley High School in a trade for marijuana appeared in Spokane Superior Court Thursday.

Judge Shelley Szambelan set Kinski Riten Biten’s bond at $10,000. Biten faces charges of second-degree unlawful possession of a firearm, possessing a dangerous weapon on school facilities, unlawful possession of a pistol (18 to 21 years of age) and possession of a stolen firearm.

Central Valley High School went into a lockout on Wednesday following a tip from a student that Biten allegedly had a gun that he swapped with another student for marijuana in a bathroom at the high school.

The other suspect, a juvenile, was arrested and sent to a juvenile detention facility Wednesday.
