Joshua Hosmer, 40, was last seen on May 31, 2016, at his sister’s home in Sacramento, California. Early that morning he left with two unidentified men in an unknown vehicle. A few weeks later he phoned his mother from Tennessee saying he had been abandoned and needed money; his mother sent funds and that was the last confirmed contact.

Hosmer was not working and lived a transient lifestyle, traveling around the country to attend Grateful Dead concerts. He has a metal rod in his ankle and a coral implant in his skull from a prior car accident, and several distinctive tattoos including a Grateful Dead logo and a deer head on his left forearm. Authorities have received few leads and the FBI alongside local law enforcement continue to investigate.

If anyone remembers seeing Joshua after May 31, 2016, or has information about the two men or the vehicle he left with, please share tips with investigators.
