ORIGINAL REPORT:
SPARKS, Nev. -- SPARKS, Nev. (AP) -- A student at a Nevada middle school opened fire on campus just before the starting bell Monday, wounding two boys and killing a staff member who was trying to protect other children, Sparks police said Monday.
Twenty to thirty students were witnesses to the tragedy that also left the lone suspected gunman dead, police said. It's unclear whether the student committed suicide, but authorities say no shots were fired by law enforcement. Police said between 150 and 200 officers, including some from as far as 60 miles away, responded to the shooting.
"In my estimation, he is a hero ... We do know he was trying to intervene," Reno Deputy Police Chief Tom Robinson said about the fallen staff member.
