Levar D.T. Mullen was 20 when he was shot to death on April 11, 2019, in the 2800 block of Parkwood Avenue in Baltimore. The daytime attack wounded four people; Mullen was the only victim who did not survive. Three other people were treated for gunshot injuries.

Investigators identified 26-year-old Donte Patterson as a suspect after surveillance footage showed a vehicle connected to him arrive at the scene with multiple occupants who then carried out the shooting. That vehicle was linked to a different double homicide that occurred the night before, and evidence seized from Patterson’s phone, including a video taken about an hour before the April 11 shooting, was used in the investigation. Patterson was arrested on April 17, 2019, and his vehicle was recovered.

Prosecutors described the killing as a revenge attack. A jury later convicted Patterson of second-degree murder, attempted second-degree murder, conspiracy to commit murder, and use of a firearm in a crime of violence; he received life plus 52 years, with at least 15 years of the life term to be served without parole. Did anyone in the Parkwood Avenue area see or hear anything that morning that could add context to what happened?
