Steven Davis turned in his Bushmaster semi-automatic and was hospitalized after friends were concerned about strange behavior.
Davis voluntarily surrendered the Bushmaster AF-15, the same rifle used in the Newtown, Conn. massacre, as well as two high-capacity magazines on Monday, said Bennington Police Chief Paul Doucette. Police later seized about 500 rounds of ammunition during a search of Davis’ home.
Alarmed neighbors called police when they saw Davis walking to his car with the rifle.
Described as as a well-liked math and science teacher at Mount Anthony Union High School, Davis had recently become disgruntled with his job, posting a series of videos to YouTube in which he criticized the school’s administration and union.
In one video, said he had plans for retribution.
“This is all planned and very well thought out … I’ve studied military tactics and this is the way to go. It’s all going to hit so hard, so fast and shut that school system down til they get things straight.”
