Who is Boo Radley, and what are the rumours about him in Maycomb? What are the events that led up to his current predicaments?

Boo Radley is a recluse who never emerges from his house. As a young boy, he was in trouble with the police, and his strictly religious and reclusive parents have kept him indoors ever since. A prisoner in his home, he stabbed his father with scissors once, and no one has seen him since. The town has developed a myth that he is an insane monster who wanders around at night peering into people's windows. Throughout the book, he lives with his brother, who is highly controlling.
