Rogelio Delarosa Jr., 34, of Peoria, Illinois, was found dead on December 2, 2014, with multiple gunshot wounds behind a home in the 1000 block of Northeast Perry Avenue. He had moved to Peoria earlier in 2014 to live in a transitional center after serving time for a federal weapons charge and left his job during a dinner break on the day he died.

Investigators found Delarosa was involved in selling the synthetic drug K2. Authorities say a blue van picked him up from work; prosecutors later argued that Tray B. Hargrow, 24, who was staying in a federal halfway house in Peoria, and others planned to rob Delarosa. Prosecutors said Hargrow was legally accountable for the murder even though the person who fired the shots was believed to be another man who had died and was never charged.

The case was prosecuted as a robbery-related homicide tied to Delarosa’s K2 sales. Does anyone have information about Delarosa’s movements that day or about the blue van and who else might have been involved?
