Gall was relieved of duty around 6 p.m. on March 12 and told he would be placed on administrative leave the following day, Thornton said.
After Gall was notified of the internal investigation, "his service revolver and badge were taken," Thornton said at the time. "Not a whole lot occurred after that. Apparently he left."
Troopers at the detachment were soon called out on an unrelated incident, Thornton said.
After responding to the call, troopers returned to their detachment. When they didn't find Gall there, they went to his house.
"The door was unlocked, they knocked and there was no response," Thornton said. The troopers then found Gall on the back porch.
Gall was with the department for 10 years, one in Martinsburg and the rest in Romney. He was not married and had no children, Thornton said.
Gall was the second State Police officer to commit an apparent suicide in the past year. Marlo Gonzales, a 13-year veteran of the force, shot himself in July with his service weapon inside his police cruiser while outside his father-in-law's house, police said.
State Police announced in January that they would implement yearly behavioral health screenings for troopers, based on recommendations from a panel studying suicides among law enforcement.
"This is really tough, the way this whole thing comes about," Thornton said. "My heart goes out to [Gall's] family. They are a couple of months removed from the situation."
