Maryland Gov. Larry Hogan said Gaskill is a “… tough guy” who “took the right kind of action.”
“I think that while it is still tragic, [Gaskill] may have saved the lives of other people,” Hogan said.
Gaskill interaction on Monday with the death gunner, the 17-year-old Austin Wyatt Rollins, it was not the first time he came face-to-face with a firearm.
This photo of the shooter, Austin, Wyatt, Rollins, 17, was posted on his Facebook in May 2014. Deputy Gaskill was credited with Tuesday’s high school shooting within a minute of Rollins’ first shot is fired.
In July 2016, Gaskill was responding to a complaint, on a Great Mills home when a man — identified as Pekka Robert Heinonen, 59 — pointed a gun at him, according to the Maryland newspaper The Company.
Heinonen was “standing on the porch, pointing a gun at me,” Gaskill wrote in a probable cause statement. “I ordered the suspect to drop the gun, at which point … his wife walked between us. The defendant refused to comply with my demands, … [until his wife] convinced him to drop the gun.”
Gaskill, Sheriff Cameron said at the time, “exemplary judgment” in the situation, in which “realistic, relevant and constant training clearly paid off.”
The deputy with the St. Mary’s County Sheriff’s Office for six years, after he previously spent four years as a correctional officer.
