David Lamont Martin, 33, was fatally shot on September 14, 2000, near the Los Angeles River in Los Angeles, California. His death was the result of a violent crime; investigators believe Martin was an unintended witness to another murder and was shot to eliminate him as a witness.

The primary suspect in the cases has been Timothy Joseph McGhee, identified as a Toonerville gang leader with a history of gang-related violence. McGhee has been linked by investigators to multiple killings, including that of 17-year-old Marty Gregory Roybal, and authorities say evidence including witness testimony and forensic analysis connected him to the murders of both Roybal and Martin.

Martin’s death is one of several that illustrate the deadly reach of gang violence in northeastern Los Angeles at that time. If anyone knew David Martin, saw activity near the Los Angeles River on or around September 14, 2000, or has information about the shootings, please come forward.
