But leaving a running car in a garage, even open, is such a bad, dangerous, irresponsible idea. He should get off his games and be a caretaker, not a child.
Where were the other two children at the time the 2 year old was in the car? The 9 year old and the 5 year old were not likely in school. Were they in the house with him? Was he putting them in a position to care for the little one?
LE will probably find out there are other ways he has been shirking childcare duties for his own private times. I sense there have been problems in this marriage before.
Has he been in charge of child care for 9 years ? ( the oldest child is 9). This family certainly would have had the means to hire a babysitter.
