Authorities say the student who opened fire on a Nevada middle school campus, wounding two students and killing a teacher, got the weapon from his home.

Washoe County School District Police said Tuesday they are still working to trace where the gun was bought. Police said a Sparks Middle School student was the lone shooter and turned the weapon on himself. (Associated Press)
