The man has been identified as Joseph M. Jaquez, 31, of Aurora, according to the Will County Coroner's Office. He had been shot once in the head before his body was placed in the trunk of a car that was set ablaze early Thursday...

Ackerson said Jaquez had not been reported missing and detectives were working Friday to "backtrack" who he'd been in contact with.

Joseph M. Jaquez was identified through dental records, according to a statement from the sheriff's office Friday morning.

Jaquez was found in a rented Dodge Charger along Patterson Road west of Brandon Road in Joliet Township after midnight, authorities said.
