Rudolph Horton was 36 when he was shot and killed in Baltimore on September 6, 2012. An African-American man, Horton’s death came during a particularly violent year for the city, and it added to the heavy toll local neighborhoods were experiencing at the time.

The investigation faced immediate obstacles. Police reported a lack of cooperating witnesses and struggled with a high volume of violent crime, which hindered progress. No suspects or arrests have been publicly identified, and the case remains unresolved.

Anyone who knew Horton or who has information about the shooting in the area on or around September 6, 2012, is asked to come forward.
