WBAL Radio obtained still photos from the Baltimore County state's attorney's office of the scene during an Aug. 27 shooting at Perry Hall High School.
The photos show shooter Robert Gladden with a gun, and school staff tackling the 15-year-old after he fired a shot, injuring student Daniel Borowy.
Gladden was sentenced to life in prison, with all but 35 years suspended, for the attack on Monday.
