Tracy police said he turned over a realistic-looking BB gun that his parents were unaware of. No other weapons were found during a search of the home.

“Let us be perfectly clear, making criminal threats to harm others has no place in a civilized society. We will not tolerate it in our community and will use the full weight of the justice system to bring those responsible to justice. The loss of life is not a joking matter,” Tracy Police Sgt. Mario Ysit said.

The teen was in custody on a charge of making criminal threats against a school.
