Very same thing happened in Iowa not too long ago. A hospital CEO left her infant strapped in the carseat - found it when she went out to the parking lot after the workday. She didn't go to prison, (although I think there might have been a trial, can't remember) and I think she went back to work at the same place. Weird.
The next think is a government law mandating beepers if a baby is left in the back seat, kinda like when you leave your keys in the car. I'm being sarcastic.
