“The U.S. Attorney’s Office dismissed the charge without prejudice and the case remains under investigation,” spokesman William Miller said. “Because the investigation is continuing, we have no further comment.”
Hall died on September 10 after he was stabbed three times the night before in the 4000 block of 1st Street Southeast, documents say.
Surveillance footage from a 7-Eleven showed Hall entering the store while an unknown subject dressed in all back stood outside.
A police officer identified the man in the photo as Sweeney, who the officer often saw in front of that 7-Eleven.
