Like that scene in Chasing Amy, only not funny

This has got to be one of the most f-ed up stories ever:
One of my roommates, Jennifer, was at the grocery store today when she saw a little boy (about 3 years old) playing in a car by himself. Somehow, he managed to put the car in reverse and it started rolling toward a building. Jen lunged into the car and was dragged across the parking lot, but she was able to stop the car before the kid was hurt. When the father came out of the store, she explained what had happened and told the man that she had called 911 and needed to be taken to the hospital. This asshat pushed her out of the way and drove off. ?! She remembered part of the license plate, and has to file a police report tomorrow. He'll be charged with child endangerment (he didn't even have a carseat for the kid) and leaving the scene of an accident. Jen ended up with a hairline fracture in her wrist, multiple cuts down her back and legs, and possibly a dislocated shoulder. But at least she (and the kid) are ok.
