Michael Alexander Rudolph, 49, disappeared from Camarillo, California, after leaving his home on June 20, 2006. A neighbor called his disappearance highly unusual. His maroon 2000 Ford Contour turned up three days later parked near Mugu Rock beach.

Authorities at first considered suicide or accidental drowning. By late 2009 investigators shifted to suspect foul play and suggested someone may have staged his disappearance. Rudolph had been involved in real estate deals in Costa Rica and planned to move there; police say those connections are suspected to be linked to what happened. A person of interest has been identified but not publicly named. His family described him as friendly and enthusiastic about surfing and the planned move.

The case remains unsolved and foul play is strongly suspected. Did anyone who knew Michael or his Costa Rica contacts hear anything around June 2006 that could help investigators?
