Baltimore County Police released a video of a car they think may be connected to the crime from surveillance video a few blocks away.

Police say a white car, possibly a Lexus with distinct rims, left the scene shortly after Arca-Jones was shot.

“We want to locate the car, and we want to identify what part they played in the crime, if they played any part at all,” Vinson said. “They might have been a witness.”

Police say their homicide detectives exhausted all other leads in this case.
