Derrick A. Doyle was 21 when he was shot and killed in Pineville, South Carolina, on September 4, 2010. His death prompted a multiagency investigation led by the Berkeley County Sheriff’s Office with assistance from the FBI and the South Carolina Law Enforcement Division. Authorities concluded the killing was a targeted homicide and investigated whether it was premeditated and gang-related.

Several people were identified by investigators as believed responsible. One primary suspect, Jay Quan Washington, was arrested and charged with murder and possession of a firearm during the commission of a violent crime. Donelle Lamar McKelvey was charged as an accessory before the fact of murder. The family — his mother, two brothers, and a sister — followed the legal proceedings as evidence and testimony were presented.

If anyone knew Derrick or has information about the events leading up to September 4, 2010, please come forward.
