Grimm was last seen in Palm Springs, California on November 23, 2000. He has never been heard from again. He has links to West Hollywood, San Francisco, and Los Angeles, California. He has ties to Miami, Florida and to Houston, Texas, well; he grew up in those areas and in southern California. Both California and Texas police are investigating his disappearance. In January 2001, Grimm's family received an anonymous telephone call; the caller stated that Grimm had been shot to death shortly after his disappearance. This information has not been confirmed, but investigators consider his disappearance suspicious and foul play is possible in Grimm's case. His case remains unsolved and is being investigated as a homicide.
