Two boys, ages 5 and 6, are in serious but stable condition after being shot at their Christian school in Northern California. The suspected shooter died from a self-inflicted gunshot wound after he opened fire on the pupils, reports ABC News.

Butte County authorities went to the Feather River Adventist School near Oroville after hearing about an active shooter. A highway patrol officer discovered two injured students and the shooter’s body nearby. The shooter had talked to a school administrator earlier that same day about enrolling a student. Reports say that the school teaches students from Kindergarten to 8th grade.

Officials mentioned it’s unclear if the meeting was real or a stunt for the shooter to enter the school. It seemed friendly, and the administrator had no concerns. Shots were blasted shortly after the meeting, and officials are investigating a possible motive, which they believe could’ve been connected to the fact that the school is linked to the Seventh-Day Adventist Church.

Kory Honea, the Butte County Sheriff said,

“Out of an abundance of caution, we sent an alert out to law enforcement agencies throughout the state of California, advising them of this shooting and advising them that the subject may have targeted this school because of its affiliation with that particular religious organization.”

He continued,

“Our request of those law enforcement agencies was to be vigilant and make sure that those schools are safe and the students are still safe.”
