Here's what we know about the Maryland high school shooting

A 17-year-old gunman fired a Glock 9-millimeter gun at a 14-year-old boy and a 16-year-old girl at 7:55 a.m. in a hallway at Great Mills High School in Southern Maryland on Tuesday.

The alleged shooter died after a confrontation with a school resource officer.


Details about the shooting are still developing, and the investigation is ongoing. Here’s what we know:

» The shooter was identified as Austin Wyatt Rollins, a student at Great Mills.

» The 16-year-old victim of Tuesday’s shooting at Great Mills High School — identified by family as Jaelynn Willey — died Thursday night after being taken off life support.

» The 14-year-old boy was identified as Desmond Barnes. He was shot in the thigh and was discharged from the hospital Wednesday, officials confirmed.

» As school systems across the country debate arming staff, state and local officials praised the actions of the school resource officer who fired at the gunman. As Gaskill fired at Rollins, Rollins “almost simultaneously” fired his gun.

» Rollins died by shooting himself in the head, officials said Monday. The Great Mills school resource officer, Deputy First Class Blaine Gaskill, responded to the shooting and “engaged” Rollins, according to the St. Mary’s County Sheriff’s Office. Rollins fired one fatal shot to his head, while Gaskill simultaneously fired his gun, which struck Rollins in the hand, the sheriff’s office said.

» The sheriff’s office said that the shooting was not a random act. There’s evidence that Rollins and Willey had “a prior relationship which recently ended,” according to the sheriff’s office.

» The St. Mary’s County Sheriff’s Office said Wednesday that the gun used by Rollins was legally owned by his father.


» Students at Great Mills posted on social media sites Snapchat and Twitter during the deadly shooting. As school shootings become more common, so do social media images depicting them.

» Great Mills High School in St. Mary's County will remain closed for the rest of the week, as the school community deals with the shooting’s aftermath. Schools will be closed next week for spring break, so Great Mills High is expected to reopen April 2.

» The St. Mary’s County students flipped off the lights and put paper over the small windows in the classroom doors. Their teacher was outside. He had run in the direction of the gunfire. With the recent school shooting in Parkland, Fla., in many minds, one 17-year-old junior realized: “This was the real thing.”

» The shooting was not the first instance of school violence in the state. Violent incidents have occurred in and around public schools across Maryland for years, in urban and suburban areas, inside school buildings and outside their walls, involving students and others who targeted them.
