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 else, other than the woman, was in the car, 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?

Edit: Slight typo. Sorry folks.

In that case, a few more possibilities:

1) The woman opened the door for the stranger (easy from the inside) - wife was either already dead or was the woman and was killed by the stranger.

2) Stranger to who? Most readings will assume that the riddle means stranger to the man, but that isn't necessarily the case. I haven't met this woman, so she is a stranger to me. The woman could thus be the stranger, and have already been in the car. With such a case, the wife would have already been dead, or the wife was the woman and died from heat stroke/heart attack/whatever (if a dead person can qualify as a stranger).

3) If stranger doesn't imply human, it could refer to an insect/spider/rodent/whatever that got in; cars aren't usually air-tight. If the woman was the wife, she could have died from something while in the car (perhaps a bite). If the woman was not the wife, the wife was already dead.

4) The stranger could have gotten in if the woman rolled down a window. Then, either the woman was the wife and the stranger killed her or the wife was already dead.
