Devon Erickson, 18, has been identified as one of the two suspects who allegedly opened fire on STEM School Highlands Ranch in Colorado on Tuesday afternoon. Devon Erickson 18-year-old has been identified as one of the two students who opened fire on a school in Denver. An 18-year-old boy was killed and eight other students were injured when gunfire erupted at STEM School Highlands Ranch on Tuesday afternoon at 1.53pm local time. Police confirmed that the shooting was carried out by two people, one adult male and one juvenile. The Douglas County Sheriff's Office confirmed Erickson is the adult shooter. Officials are expected to release more information at a press conference at 6am Wednesday morning. Douglas County Sheriff Tony Spurlock said shots were fired in two separate locations in the high school section of the campus, which serves grades kindergarten through 12th. Administrators reported the gunfire immediately and deputies arrived on the scene within two minutes. Spurlock said officers engaged the suspects and there was a struggle to bring them down. Neither suspect was injured in the confrontation. Authorities recovered three handguns and a rifle but said the latter was not used in the shooting. Before officers arrived, one heroic student, Brendan Bialy, tackled one of the gunmen. Bialy's father told the New York Times that 'two students entered the classroom and one pulled a gun out of a guitar case'. He said 'his son and two friends tried to tackle the gunman but one of the boys was shot in the chest', according to the Times. That account was corroborated by the father of one of the teenagers who was shot. Fernando Montoya told The Denver Channel his son, who was shot three times but is expected to survive, told him a shooter produced a gun from a guitar case.
