Nicolas Sonderegger, 27, was last seen on September 9, 2018, in Salton City, California. He disappeared from the home he shared with a friend identified as Austin, leaving his wallet and vehicle at the residence. The night before he vanished the two heard a scream outside; Austin fell asleep and by morning Nicolas was gone.

Searches turned up some of his clothing nearby, but otherwise yielded no significant leads. Nicolas posted on YouTube under the name SunSpeik. Family and friends have pushed for answers and a $10,000 reward has been offered for information. Investigators continue to work the case but describe the surrounding desert as a complicating factor.

If anyone knew Nicolas, lived near Salton City in 2018, or has information about what happened that night, please come forward.
