The 45-year-old was killed while trying to talk to the unidentified 12-year-old gunman, who later killed himself. "He was telling him to stop and put the gun down," student Jose Cazares told Today on Tuesday. "Then the kid, he yelled out, 'No!' Like, he was yelling at him, and he shot him. The teacher was calm, he was holding out his hand like, 'Put the gun in my hand.' " Students, parents and fellow teachers are calling Landsberry's actions heroic. Tom Robinson, vice chief with the Reno Police Department, also praised him, saying, "In my estimation, he is a hero. We do know he was trying to intervene (,)."

"It's just so sad knowing he left because he protected his students," one of the posts said, followed by another that read, "The sad part is this week it's his and his wife's anniversary and his daughter graduates from the military tomorrow." CNN reports that two students who were wounded by the shooter - who used a Ruger 9 mm semi-automatic handgun - are currently in stable condition in hospital. Authorities will not be releasing the identity of the shooter out of respect for his parents, but schoolmate Amaya Newton was shocked by his actions, calling the gunman "a really nice kid," adding, "He would make you smile when you were having a bad day."
