David Paul Santiago, 22, was fatally beaten after an altercation outside a rave in Phoenix on November 25, 2012. The event was at a venue on North 23rd Avenue; around 1:15 a.m. a fight in the parking lot escalated when one man punched Santiago, knocking him down, and a second man stomped on his head. He was taken to a hospital but died ten days later from his head injuries; the Phoenix Police Department ruled his death a homicide.

Investigators described one suspect as a Hispanic male with light skin, about 5 feet 9 inches to 5 feet 10 inches tall, 180 to 190 pounds, brown hair, last seen wearing a red shirt. The other suspect was only described as a thin-built male. An estimated crowd of about a thousand people had been at the rave, but despite a Silent Witness reward and public appeals, no arrests have been announced.

Anyone who was at the venue that night or who may have seen the two men in the parking lot is asked to share information that could help resolve this case.
