Witnesses said the man lost control of the Jeep Cherokee and drove into the retention pond located at East Stop 11 Road and South Arlington Avenue. The jeep submerged quickly with the man trapped inside.
The witnesses called 911 and tried to release the man trapped in the vehicle. They said he was under water for approximately 30 minutes.
The Indianapolis Fire Department said one witness, 54-year-old Joe Winn, attempted to rescue the man. Winn told firefighters he was able to break the back window of the jeep with a grease gun. However, he said he was unable to find the victim before he needed air.
Greenwood Fire Department divers were able to recover the victim when they arrived. The diver, Captain Steve Dhondt, said he found the victim located in 8 feet of water, 20 feet from shore. The water temperature was approximately 44 degrees.
Police are investigating whether the victim may have suffered a medical condition before driving the vehicle into the pond.
"He was unconscious when they pulled him out of the water,” said IFD Rita Burris. “CPR was initiated. He was placed in the back of an ambulance and transported to St. Francis South."
Police said the man was later pronounced dead around 10:35 a.m.
His identity is not being released until his family is notified.
An autopsy is scheduled to determine the exact cause of death.
Meanwhile, several nearby neighbors made note of the fact that there was no guard rail around the pond at the busy intersection.
Resident David Roll expects the issue to come up at his next homeowners meeting.
"I hope they do,” said Roll. “I think it would be a good thing."
