SPARKS, Nev. (AP) -- Police say the 12-year-old student who opened fire on a Sparks middle school campus, got the weapon from his home.
The boy wounded two classmates and killed a teacher before he turned the gun on himself.
Washoe County School District police say they are still working to determine how the boy obtained the 9mm semi-automatic Ruger handgun used in the Monday morning spree at Sparks Middle School. The boy's parents are cooperating with authorities and police say they could face charges in the case.
Authorities say they're withholding the seventh-grader's name out of respect for his family.
At a news conference Tuesday, law enforcement and school officials again lauded the actions of 45-year-old math teacher and former Marine Michael Landsberry, who tried to stop the rampage before he was killed.
