Chicago police discovered the bodies of two men inside a white Camaro parked on a street in West Englewood.
It happened on the 7100 block of South Oakley Wednesday afternoon, while officers were conducting a well-being check.
One of the adult victims was in the back seat, the other was in the trunk.
Their names have not been released. One of the victims reportedly worked at the Daley Center for nearly a decade and had just bought a home with his fiance.
