A pair of 10-year-old students were arrested Tuesday at Silverdale Elementary School after a teacher discovered a handgun in a backpack.

Kitsap County Sheriff’s deputies arrested the two boys without incident for conspiracy to commit assault at about 3 p.m. Tuesdsay, according to a sheriff’s office release.

The arrest came about after one of the boys asked the other earlier this week to bring one of his father’s guns to school. The second boy complied, and Tuesday morning brought a .40 caliber semiautomatic pistol to a school bus stop the boys shared, according to the release.

Authorities did not release names of those arrested

The first boy said to the second that he wanted to use the gun to assault members of his own family, authorities said.

The two boys tried and failed to fire the weapon in a clearing near the bus stop, then put the gun in one of their backpacks and boarded a school bus. On the bus they showed the gun to other students. After the pair arrived at school the presence of the gun became known to a teacher at the school, who found the gun and brought it to the school’s office, according to the release.

A responding deputy rendered the weapon safe, finding it loaded and with the safety off but without a round in the chamber. Sheriff’s detectives then arrived and arrested both boys.

Both boys face charges of conspiracy to commit assault with a deadly weapon. The second boy also faces two charges relating to unlawful possession of a firearm, according to the release.
