Prince George’s County police have identified the officers involved in a Friday shooting that left one man dead after he refused to put down a pellet gun that resembled an assault rifle, authorities said.

Cpl. Vincent Tabbs and Officer Andrew Nacin have been placed on routine administrative leave as the department investigates the shooting that left a Suitland man dead.

The deceased suspect has been identified as 20-year-old Mark Anthony Blocker of the 3300 block of Curtis Drive in Suitland, police said Friday.

The incident began when police were called to that block of Curtis Drive about 2:15 a.m. Friday, authorities said. Officers arrived at the scene after receiving reports that a man wielding a “long gun” was arguing with another person outside an apartment building.

Officers saw the man with what appeared to be an assault rifle and commanded him to drop the weapon, police said. When the man refused to comply, officers who were “in fear for their lives” fired their guns and hit the man, authorities said. Police later discovered that the weapon Blocker had was a pellet gun “manufactured to look as realistic as possible.

Police also recovered a pellet gun resembling a handgun from the scene.

Blocker was pronounced dead at the hospital, and Tabbs and Nacin were uninjured.
