A terrifying day for an 82-year-old man who backed out of his driveway Tuesday, then plunged into a river.
Another driver watched it happen and called for help.
At that same time, a Grosse Ile police officer happened to be driving by.
That officer was able to break a window and rescue the driver.
The man is recovering.
Police are now trying to figure out if he had a medical issue that caused the accident, or if he possibly hit the gas instead of the break while backing out.
