The man who police said fired at two Prince George’s County officers before they shot him on Southern Avenue Tuesday night has been charged with assaulting a police officer, authorities said Thursday.

Marcellus Williams, 21, remained hospitalized in stable condition Thursday, still recovering from the wounds he sustained in a gun battle police say he initiated with two Prince George’s officers. A D.C. police spokesman identified him and said he was charged with assaulting a police officer.

Also Thursday, Prince George’s County police identified the officers who shot and wounded Williams as Paul Schweinsburg and Khaled Rasuli. The two were investigating 911 calls about someone shooting a handgun into the air when they spotted Williams in the 800 block of Southern Avenue about 10 p.m., police have said. Police have said Williams refused the officers’ demands to drop his weapon, instead raising his gun and firing several rounds at them.

Schweinsburg and Rasuli, police have said, returned fire and hit Williams several times. The officers were not hit by any of Williams’s shots, police have said.

The incident occurred in D.C. because the Prince George’s border ends at the sidewalk along the Maryland side of Southern Avenue, police have said. Still, officers from both the District and Prince George’s are authorized to drive along Southern Avenue and respond to crimes that occur there, police have said. In this case, police have said, Schweinsburg and Rasuli appear to have acted appropriately.

Schweinsburg, a five-year veteran, and Rasuli, who has worked for the department for about a year, were both placed on administrative leave while D.C. police and Prince George’s internal affairs detectives probe the incident — standard practice for police-involved shootings.

Efforts to find family members for Williams were unsuccessful.
