Adam Kellner was last seen on November 8, 2007 in his home in Stevenson Ranch, California. Adam had been diagnosed with schizophrenia years earlier when he was in college. At the time of his disappearance, he was living with his mother, Sherrill Britton, and his stepfather. He lived a very isolated life and rarely left home. He simply vanished and no trace of Adam has ever been found.
