The Independent Investigations Division of the Office of the Attorney General, a unit that probes all fatal counters with police, released the first initial and last name of the three shooting officers: S. Johnson, a 16-year veteran; C. Klapka, a 4-year veteran; and R. Fitzgerald, a 3 1/2-year veteran.

It’s unclear if one of the named officers is the one who was hit. All three are assigned to the Operations Bureau with the Baltimore County Police Department.

Baltimore County police officers initially responded to a report of “unknown trouble” in the 500 block of Virginia Avenue on June 4 about 8:40 p.m., police said.

When they arrived at the location, they heard gunshots coming from inside a building.
