Authorities say they're withholding the Sparks Middle School student's name out of respect for his family. But Washoe County School District Police Chief Mike Mieras released the seventh-grader's age at a news conference Tuesday.
District police say the boy brought the weapon used in the Monday morning spree from home. They're still working to determine how he obtained the 9mm semi-automatic Ruger handgun.
Police say the boy's parents are cooperating with them and could face charges in the case.
Also at the new conference, police lauded the actions of 45-year-old math teacher and former Marine Michael Landsberry. They say he tried to stop the rampage before he was fatally shot in the chest.
