Teen Arrested in Alleged Mass Shooting Plot at a Washington State Mall

The FBI and Columbia County officials arrested a juvenile Oregon resident on May 22, 2025, for planning an attack at Three Rivers Crossing in Kelso, Washington.
The investigation was launched after the FBI was alerted on May 19 to specific and urgent plans for an attack, which had been shared online by the juvenile suspect.
The suspect's plan involved detonating an improvised chlorine bomb, shooting fleeing mall patrons near a movie theater, and ending the attack by suicide within the mall.
FBI Portland Special Agent Douglas Olson said, "This plot was as serious as it gets," noting the suspect included annotated mall schematics, a route, weapons, and clothes in their plan.
Authorities executed a search warrant, seized firearms and digital devices, and emphasized the importance of reporting suspicious behavior to prevent such violent acts.
