I have a friends dad who started their car in the garage on a cold day, walked away for time then returned. Took a breath and passed out.
Mom noticed he was still home, went to the garage, saw him on the floor, tried to help but was overcome by fumes, too.
Tragic but it happens.
That reminds me of this story I posted 4 years ago...
Family of 3 found dead (Car left running in Garage)
