The student who opened fire at a Sparks Middle School in Nevada got the gun from his home, police said Tuesday.

Washoe County School District Police say they are working to trace where the gun was purchased. Police say the student was the lone shooter in the incident that left a teacher dead and two students wounded before the student turned the gun on himself. The student is not being named out of respect for his family, authorities said.

The two students who were shot are in stable condition and are recovering. One of the boys was shot in the shoulder, and the other was shot in the abdomen. Both boys are 12.

Teacher and former Marine Michael Landsberry, 45, tried to stop the rampage before he was fatally shot, police said. Landsberry is being hailed a hero for trying to protect his math students. Police say his actions gave the kids enough time to run to safety.

It was no shock to family members that Landsberry, who was married with two step daughters, would take a bullet.

"To hear that he was trying to stop that is not surprising by any means," Chanda Landsberry said. She added his life could be summed up by his love of family, his students and his country.

Authorities did not provide a motive for the shooting.
