Delmond Blackbird Carter was 31 when he was shot and killed on May 15, 2010, in San Francisco. The shooting happened in the early morning while Carter was fixing a car in a parking lot at LaSalle and Ingalls Streets in the Bayview-Hunters Point neighborhood.

The suspect or suspects remain unknown and no arrests have been announced. The San Francisco Police Department has offered a $100,000 reward for information that leads to an arrest and conviction, and authorities say tips can be submitted anonymously. Carter’s family continues to seek justice for his loss in a case that remains one of San Francisco’s unsolved homicides.

If anyone knew Delmond, witnessed the shooting, or has information about that parking lot that night, please share what you know with investigators.
