SPARKS, Nev. - A student at a northern Nevada middle school opened fire on campus Monday morning, wounding two boys and killing a teacher who was trying to protect other children.
Police say 20 to 30 students witnessed the shooting at Sparks Middle School.
The suspected gunman also was dead, but it's unclear whether the student committed suicide. Authorities say no shots were fired by law enforcement.
Reno Deputy Police Chief Tom Robinson said the teacher who was killed was trying to protect other students.
Family members identified him as math teacher Michael Landsberry, a 45-year-old military veteran who leaves behind a wife and two stepdaughters.
Spokeswoman Angela Rambo of Renown Regional Medical Center says the two boys are in critical condition.
The names of the suspect and two other victims have not yet been released, and the motive for the shooting is still unknown.
Sparks Mayor Geno Martini called the shooting "an isolated incident."
Sparks is a city just east of Reno.
