They did not, but they have said that it's 2/10 of a mile and did say that it was a matter of minutes. (I will look for that link.)
I do think forgetting a child in a car CAN happen, but I don't think it has to or should. I think it happens to all walks of life, but they all have one thing in common. They aren't slowing down to think of their child first, and their priorities are negligently out of place. I think there should be no tolerance and it should be a crime every single time a child dies or is severely injured in a hot car. This case shows gross negligence and IMO can't be compared to other cases.
