PORTLAND, Ore. (KOIN) — A 27-year-old woman is in custody after her gun was discharged inside a Portland elementary school cafeteria Thursday afternoon.

According to a letter sent to Jason Lee Elementary School families, Antoinette Riley was picking up her child from an after school program when she dropped a bag that had a gun in it.

The gunshot tore a hole in a table and bench.



No one was hurt, but the school went into lockdown and police responded. Police are investigating the incident.

Police said they found Riley based on a 911 caller’s description. She was taken into custody a few blocks away but did not find the gun.

Police don’t believe she intentionally discharged her weapon or that there is any danger to the school or community.

Police have had canines search around the school but have no found the gun. They are warning parents to tell kids not to touch it if they find it — it might still be loaded.

“This is an alarming incident and we are thankful that no one was hurt. Keeping our students safe is a responsibility we take very seriously. As our highest priority, we will look at every opportunity to ensure a safe environment. We are working to ensure we have counselors and other support staff at school in the morning to provide assistance to students and staff,” assistant principal Blake Robertson wrote.

The school district is reviewing procedures to see what it can do to prevent another situation like this.

“You’re not supposed to have firearms on campus,” parent Jeff Marks told KOIN 6 News. “When you have that on campus and accidents happen, it’s not an accident …”

Riley was booked at the Multnomah County Jail, but has since been released. She was charged with possession of a firearm in a public building.
