Hans Lippuner, 59, was last seen by his housemates on October 16, 2018, at the Dows Prairie residence where he lived with his best friend and the friend’s wife. A skilled craftsman, tree climber and outdoor enthusiast, Lippuner had been showing signs of depression in the weeks before he vanished, losing weight and withdrawing from his usual projects. He left most of his work and climbing gear behind.

Lippuner drove off in a white 1998 Ford Econoline van; the vehicle was found abandoned in a remote area near Del Loma, California, about two months later. His family reported him missing on November 1, 2018, after realizing nobody had seen or heard from him for weeks. Extensive searches have turned up no trace, and the Humboldt County Sheriff’s Office continues to investigate. Some suggest he may have chosen to disappear given his declining mental health, while his family remains concerned about possible foul play.

If anyone saw Hans or his van in October 2018, or has information about his whereabouts, please share what is known.
