He was the third of five boys. Pelzer wrote in his book that as a child he was continually abused, mistreated, and beaten by his mother, who thought of it as a game. The book documents how his mother starved him, forced him to drink ammonia, stabbed him in the stomach and forced him to eat his own vomit. His teachers stepped in on March 5, 1973 and 12-year-old Pelzer was placed in foster care. In 1979, he joined the Air Force and later became an author. The fourth boy, Richard B. Pelzer, has also written about his own abuse.
