SPARKS, Nev. (AP) - Nevada Gov. Brian Sandoval says his office is receiving regular reports on the shooting at Sparks Middle School.
He said the Nevada Highway Patrol is assisting at the scene.
Police say two people are dead and two more are injured.
Washoe County School District Police didn't immediately offer details of the identities of the dead. Spokeswoman Angela Rambo of Renown Regional Medical Center says two boys are in critical condition.
Police said the school is "all clear" and the suspect is "down," but offered no further details. The shooting happened on the school's campus, but outside the school building itself, according to police.
Sandoval issued a statement after hearing about the shooting, saying he was saddened to learn of what he called "the horrific shooting" and extended his thoughts and prayers to those affected.
