Senior Master Sgt. Robert Garrett attended middle school with Landsberry in Reno before serving as his supervisor in recent years. He described him as a tough ex-Marine who taught with compassion and was known as a Batman fan and soccer fanatic who would do anything to help anyone.
"Every one of the people I have talked to just knew that Mike was in there," Garrett said. "He was the guy that would have jumped in there to stop the bullets from hitting other kids. And sure enough, it was."
Mayor Geno Martini praised the response from officers, who arrived at the scene within 3 minutes of the initial 911 calls to find the shooter dead.
"You can never plan for anything like this," Martini said Tuesday.
Students from the middle school and neighboring elementary school were evacuated to a high school, and all classes were canceled. The middle school will remain closed for the week, while an adjacent elementary school is set to reopen Wednesday. A candlelight vigil was planned Wednesday night outside the middle school and a multi-faith prayer vigil at a church in neighboring Reno.
Ferro's dad took the day off and the two went out to lunch together on Tuesday, a day Ferro thought might never come.
"I'm still a little shaken up, depressed and confused," Ferro said. "The whole time I was hoping Mr. L. was OK, we'd all get through it, it was a bad dream."
