The car was eastbound on Lincoln Highway when it left the road, drove across a field and into the pond, which is about 30 feet deep, Chicago Sun-Times reports. Christopher L. Stone, 27, was found dead inside the black Pontiac Grand Prix, which had inverted and was pulled from the pond off the 3000 block of Lincoln Highway late Monday. Stone lived in the 18700 block of South Island Avenue in Chicago Heights. He was not wearing a seat belt, so authorities were not able to determine if he was the driver or passenger.
A witness told police they had observed one person bob to the surface immediately after the crash and then disappear back into the water.
A police investigation led authorities to believe a second person was inside the vehicle, prompting additional search efforts last week. The followup search was called off late Thursday, and the efforts resumed Tuesday morning.
