David Gerard Berger, 36, of Greenwood Village, Colorado, disappeared while on an extended trip to Costa Rica. The last known contact was January 11, 2008; after that date he stopped communicating and did not return home. His family reported him missing and the Greenwood Village Police Department opened an investigation that remains active.

While in Costa Rica Berger reportedly formed a relationship with a local woman who was later identified as a prostitute. One of the last known conversations was Berger telling her he planned to leave the country. At the time he went missing he was described as between 5 feet 8 inches and 5 feet 11 inches, 180 to 195 pounds, with blond or strawberry blond hair, blue eyes, an appendectomy scar on his abdomen, and often wearing a Ross Reels baseball cap.

There has been no contact from him since January 2008 and his whereabouts remain unknown. Does anyone who knew David or who was in Costa Rica in January 2008 have information that might help explain what happened?
