SUITLAND, Md. (AP) -- Prince George's County police say officers shot and killed a 20-year-old man armed with a pellet gun that resembled an assault rifle.
Police say officers ordered Mark Blocker to drop the weapon, but he did not comply, and the officers opened fire.
The shooting occurred around 2:15 a.m. Friday outside Blocker's Suitland residence. Police say they were called to the scene for a report of two men arguing when the officers saw that one of them was carrying an apparent rifle.
After Blocker was shot, he was taken to a hospital, where he died. The other man wasn't hurt. Police say they discovered after the shooting that the other man was also armed with a pellet gun. Police say his resembled a semi-automatic pistol.
