MOSES LAKE, Wash. -

Upset about being grounded for being tardy for school, a 14-year-old from Moses Lake reportedly shot his parents Friday and is being charged with attempted murder.

Nathan Brooks was charged with two counts of attempted first-degree murder Monday morning. Prosecutors said Monday they are asking that Brooks be tried as an adult.

His bail was set at $500,000.

The shooting happened at the family residence in the 500 block of East Battery Friday night. Police received a 911 call just before 10 p.m. saying that gunshots could be heard coming from inside the home.

Brooks' parents, Jonathan Brooks, 38, and Elizabeth Brooks, 39, were shot at least once inside the home. Police report six shell casings were found at the home and a weapon was recovered.

Moses Lake police said Brooks was upset over being grounded over being tardy from school. He took a gun out of the family's gun cabinet, loaded it, and shot his parents, authorities confirm. The boy's younger sister was in her room at the time of the shooting and was unharmed.

Brooks attends Moses Lake Christian Academy. Stephanie Voigt, interim director at the school, received a call about the shooting early Saturday morning.

"It's been a difficult day for our family ...(that) really is what we are here, we're a very tight-knit community and so it's shocking to all of us," Voigt said Saturday.

Voigt said the school held a parent meeting Saturday evening to update parents on the shooting and how to talk to their kids about it. The school planned to have grief counselors on hand when kids return to school Monday morning.

"I don't know how anyone comes to grips with this.  It's a tragedy for the family and for the community, not just Moses Lake Christian Academy but for Moses Lake as a community," Voigt added.

A friend of the family said Jonathan and Elizabeth Brooks are "doing well." Jonathan is in a wheelchair and conscious while Elizabeth is able to communicate through sign language. Brooks family members declined to discuss the case.

Police said Nathan Brooks does not have a criminal history. A status hearing in the case is scheduled for next Monday.
