See if u can this riddle

A man and a woman were driving in their car when it broke down. The man decided to go for help at a gas station a few miles back. He made sure nobody was in the car (besides his wife), rolled all the windows up, and locked all of the sedan's doors. He went off, but when he came back, his wife was dead, and there was a stranger in the car.

No physical damage was done to the car, so how did the stranger get in?
