Expelled Kennewick student arrested after threatening another teen with a knife

A 16-year-old was arrested Tuesday for threatening a Southridge High School student with a knife.

The teen, who had been previously expelled, showed up at the school about 10:50 a.m. Monday and threatened another student with the knife, Kennewick police said in a Facebook post.

A Kennewick school resource officer arrived to the scene in less than a minute, but the suspect had already left.

Investigators also learned that the teen had threatened other students during the weekend.

Detectives watched the teen go into an apartment near the corner of Canal Drive and Buchanan Street about 11 a.m. Tuesday. Police surrounded the apartment, Kennewick police said.

When police tried to contact him, the teen walked out of the apartment with a knife and threatened officers with it.

Police used a rubber less-lethal round and had two police dogs on the scene.

After about 45 minutes of talking with the teen, he surrendered.

He was booked in to the Benton-Franklin Juvenile Detention Center on suspicion of second-degree assault, making death threats, trespassing, disruption of school activities and weapons on school property.

“(S)chool safety is our priority and anyone who jeopardizes that will be investigated and held accountable as swiftly as possible,” police said in the Facebook post.
