GRAND JUCTION, Mich. (WWJ) - The frigid weather was likely the cause of death for a man in West Michigan, as temperatures dipped into the single digits.

According to the Van Buren County Sheriff's Office, the 22-year old Florida man apparently froze to death on the side of the road, west of South Haven.

Investigators said two men -- both from Wimauma, Florida -- were in Grand Junction visiting friends when they drove into a field, in the 8000 Block of County Road 215, and their vehicle got stuck. Late Monday morning, deputies were called to the area on a report of two people who appeared to be sleeping in a car to find the driver was dead and the passenger was unresponsive, but still breathing.

The passenger, also 22 years old, was airlifted to Bronson Hospital where he was listed in critical condition.

While autopsy results are still pending, sheriff's officials said they believe "extreme cold" played a role in the man's death. As for why the men didn't try to walk to get help, investigators believe alcohol was a factor.

No names have been released as an investigation continues.
