Baltimore County police on Monday identified the officer who fatally shot a man who police said was wielding a knife and couldn't be stopped with a Taser.

They said Officer Farrelly, an eight-year veteran of the department, was the officer involved and has not previously been involved in other departmental shootings. He is in the patrol division at Precinct No., 1, Wilkens, according to police. His first name was not released. The officer was placed on administrative leave, a routine practice for officer-involved shootings.

Police said Gregory Stegall, 36, took out a knife when police approached him behind a gas station near Catonsville around 3:40 a.m. Sunday. Stegall refused to come out from behind the building, they said. He was shot once after he did not follow instructions to drop his knife, could not be stopped with the Taser, and continued to come toward the officer while pointing the knife, according to police. Police said Stegall's last known address was in the Berea neighborhood of East Baltimore, police said.
