Multiple people, including children, were injured Thursday afternoon in a shooting at Silver Rail Elementary School in Bend, Oregon, with at least two victims transported to a local hospital.

The suspected gunman was shot and killed inside the school, possibly by a bystander, according to Bend police.

Bend Police Department spokesperson Sheila Miller said the first 911 call was received around 12:59 p.m. reporting a shot fired into a vehicle near the school. Within a minute, multiple additional calls reported that a person had entered the building and begun shooting.

Officers arrived on the scene at approximately 1:02 p.m. Seconds later, the suspect was reported down inside the school.

Miller confirmed that children were among the multiple victims. Their conditions were not immediately known. The school, which serves roughly 400 to 450 kindergarten-through-fifth-grade students, was placed on lockdown.

Students were evacuated classroom by classroom and bused to Journey Church for family reunification. School activities on Friday were canceled.

Some media outlets, citing preliminary information from law enforcement sources, reported that three children and one adult were killed and that the shooter was a 16-year-old male.

Bend police had not officially confirmed the full number of fatalities or the shooter’s identity in early statements. The FBI is assisting in the investigation.

Bend-La Pine Schools Superintendent Steven Cook described the incident as a “senseless tragedy,” saying the community was “stunned and heartbroken.”

The attack adds to the chronic pattern of gun violence that continues to plague the United States, where firearms remain the leading cause of death for children and teenagers. Tracking data show dozens of shootings on K-12 school grounds each year.

Thousands of American children get killed or injured by guns annually, the flooding of the civilian market with military-grade ammunition produced at US Army facilities, and the repeated failure of successive administrations and lawmakers to impose meaningful restrictions despite recurring massacres at schools, universities, and public places.

Easy civilian access to firearms, reinforced by political resistance to tighter controls and a culture that treats gun ownership as inviolable, has left communities across the country, including elementary schools, vulnerable to such attacks.
