On April 10, 2015, 28-year-old Derek Cooper Jr. was found dead in an apartment in the 200 block of South Sixth Street in downtown Las Vegas. The Clark County coroner determined he died of a gunshot wound to the chest and sustained multiple other gunshot wounds. Police were called that night after an argument involving Cooper and two males shortly before the shooting.

Investigators developed leads pointing to two men. Jacktorian Harvey, 34, was arrested on April 30, 2015, on drug charges after police found roughly 55 grams of cocaine and crack-manufacturing equipment in his apartment; detectives were also investigating a possible link between him and Cooper’s killing. Witnesses told Metro Detective Clifford Mogg that Harvey was inside Cooper’s apartment and shot Cooper during a robbery planned by 63-year-old Ivory Hawkins. Hawkins’ body was later found in Utah on May 22, 2015, and police sought a femur sample for DNA testing. Cellphone records placed Harvey near the scene and a blood stain on his car’s front passenger seat was noted by police.

Harvey had not been charged in the homicide and remained in custody on drug charges; the homicide probe was ongoing. If anyone has information about Cooper, the argument that night, or the two men mentioned, please come forward.
