On a cold January afternoon in 2005, 76-year-old Aloysius Roland Clarke left the Riggs Bank branch in the Brookland section of Northeast Washington, D.C., and headed to his car in the parking lot. Surveillance footage reviewed by detectives shows Clarke walking toward a vehicle, a gap in the recording, then Clarke on the ground with an unknown man appearing seconds later, standing over him briefly before walking away. Clarke was found unconscious with a serious laceration to the back of his head, taken to Washington Hospital Center, and died there on January 17; the medical examiner ruled his death due to a severe head injury but could not determine whether it followed an assault with an object or a fall to the pavement.

Clarke was a longtime Washington resident and the executive director of two group homes for adults with developmental disabilities. His wallet was later missing, and detectives treated the event as a homicide, circulating a reward of up to $25,000 for information leading to an arrest and conviction. No arrest or identified suspect has been announced, and the man seen in the parking-lot footage remains unidentified. If anyone was near the 3800 block of 12th Street NE that day or can identify the man in the video, please come forward with information.
