Details of Disappearance Kellner was last seen between approximately 9:00 and 9:30 p.m. on November 8, 2007 at his residence in the 25700 block of Hawthorne Place in Stevenson Ranch, California. He lived with his mother and stepfather. At the time of his disappearance, his mother was away from home on a business trip and his stepfather was recovering from knee surgery.
Kellner was last seen when he helped his stepfather get up the stairs to bed. He normally sleeps late, so his stepfather didn't realize he was missing until 3:00 p.m. the next day. He has never been heard from again.
Kellner was extremely isolated at the time of his disappearance; he had no friends and hadn't left the house for months, except to go to doctor's appointments. He was unable to keep a job and spent most of his time smoking cigarettes in the garage or listening to music in his bedroom.
His family stated he had a normal childhood in Miami, Florida, but developed problems as a young adult. He failed out of Stetson University in his freshman year and began abusing drugs. He went to live with his mother in 1994 and was diagnosed with schizophrenia.
All of Kellner's personal belongings, including his cigarettes, clothing, identification and all his hats, were left behind at the residence. He was carrying only a few dollars at the time of his disappearance and he had no transportation, driver's license or cellular phone. His family can't think of any argument or problems he was having that might have caused him to walk out of his life, and his psychiatrist doesn't believe he was suicidal.
Since Kellner doesn't own a car and can't drive, and since none of the local bus drivers remember picking him up that day, his mother believes he might have hitched a ride out of the area. He could still be in California, or he may be in Florida, where he grew up and where his brother lives. His case remains unsolved.
