A shooting at Silver Rail Elementary School in Bend, Oregon, on Thursday, Oct. 15, left three children and one adult dead, according to sources cited by Fox News and CBS News. Reuters, as carried in wire coverage, reported the same toll, and the New York Times placed the school on what it called a grim list of American school shootings stretching back three decades.

Early reports were inconsistent. Politico initially relayed police saying at least two people were hospitalized and that the shooter was dead, while CNN and CBS reported four dead. Later coverage cited police saying a 16-year-old suspect used a long gun to shoot at the school's locked doors. That detail comes from police statements reported by wire services; the readers should treat the exact sequence of events, and the suspect's status, as still developing until Bend authorities publish a formal timeline.

The locked-door detail matters because many districts have spent years and large sums on controlled-entry systems meant to slow an attacker. Whether the doors held, and how quickly officers reached the building, are the questions investigators and parents will press in the coming days. None of the outlets we reviewed has yet reported a motive.

Because the event occurred Thursday afternoon Pacific time and the toll was reported through the evening, some figures may change. The names of the victims had not been released in the coverage reviewed. We will carry the confirmed numbers once police or the school district release them.
