Derrick Gregory Martin, a 20-year-old African-American man from Brooklyn Park, Minnesota, was fatally shot on the evening of May 24, 2010, along a well-used walking and biking path near Lake Calhoun in Minneapolis. He sustained a gunshot wound to his abdomen and his body was found next to the path. The killing occurred in a public recreational area but was not random; police said it resulted from a dispute between two groups and that the location was coincidental.

Investigators characterized the shooting as part of an escalating feud among local gangs. Martin was identified by police as a leader in the Taliban gang, which had a violent rivalry with the 19 Block Dipset gang and affiliates. He had a prior arrest for gun possession. No arrests have been announced and the case remains unsolved. If anyone knew Martin, the groups involved, or saw suspicious activity near Lake Calhoun that night, please share what can help the investigation.
