In a Car Going Nowhere — Janice Daugharty

Lonliness and rejection switch Beebee from a cry-baby to a cold-hearted killer. His mother and father divorced and gradually went from fighting over who would get to keep Beebee to fighting over who would have to keep Beebee. On his thirteenth birthday, which his mother forgot, she allows him to keep a stray puppy he found. He had always wanted a puppy but she wouldn't let him have one, and now all he wants is a car. Her car. When she refuses to let him drive her car to school, the day after his birthday, something bad switches on inside him to make him crazy.
