In the predawn hours of August 21, 2018, 23-year-old Hispanic male Lucas Perez-Diaz was shot in the head while seated in the driver’s seat of his pickup on the 2200 block of Sunrise Avenue in Las Vegas. Officers found the truck rolled backward into a block wall with the engine running; medical personnel pronounced Perez-Diaz dead at the scene. The Clark County coroner later ruled the death a homicide.

Detectives say Perez-Diaz was shot while parking by an unknown assailant who then fled on foot. The only description released was of a man wearing a white shirt and dark pants; no motive was identified and investigators received few leads. The case remains unsolved, and the family lost a young life under sudden, violent circumstances.

If anyone saw activity in that neighborhood before dawn on August 21, 2018, or recognizes the description of the man in a white shirt and dark pants, please come forward with information.
