It's not so much based on a certain family. Some say it was all in the dector's head... Or that it was based on when someone knocked on his own door as a child and asked for someone. Then the next day, he found that all empty houses had been broken into. Others say it was a mix of three different events... the only one I can remember from the list is the Manson killings. I have no idea which one is true.
