Khalsa was last seen in Casselberry, Florida on September 15, 2008. He asked an acquaintance for a ride to the bus station. He purchased a ticket to Oklahoma City, Oklahoma, but it's unclear whether he actually boarded the bus. He has never been heard from again.

Khalsa was under a great deal of stress at the time of his disappearance. He has a history of dropping out of sight and walking extremely long distances along highways. He is antisocial and prefers to live in the woods, away from other people. He previously lived in a homeless community in San Antonio, Texas, and before he went missing he said he wanted to return there. Few details are available in his case, which remains unsolved.
