Vancouver Police were called to Frontier Middle School Wednesday morning at 9:20 a.m. after the school reported finding ammunition.

Officers arrived and located over 400 rounds of ammunition, multiple knives, a handgun and the student responsible for bringing those items to the school.  The school was placed into lock down for approximately two hours while officers were at the campus.  Neighboring Pioneer Elementary was also locked down.  No one was hurt.

An 11-year-old boy, who is student at the school, was interviewed by detectives and arrested for one count of Attempted Murder and booked into the Clark County Juvenile Detention Center.

The Vancouver Police Department Major Crimes Team is continuing the investigation.

Many parents complained on social media that the Evergreen School District didn't contact them immediately when the lockdown happened.  The district did send a letter home with Frontier Middle School students, but it did not describe the severity of the incident.
