Jonas Elijah Nelson, 19, of Pasadena, California, was last seen January 6, 2019, after a hike near the Chaney Trail in Altadena with his father. His father reported him missing on January 7. Jonas has schizophrenia and bipolar disorder and reportedly did not have his medication when he disappeared.

An acquaintance reported seeing and speaking with Jonas on January 20, 2019, in the 200 block of East Sacramento Street in Altadena; that encounter briefly led to an initial report that he had been found. The family has had no further contact and Jonas has since been re-listed as missing. He is described as 6 feet 4 inches, 180 to 190 pounds, with black hair and brown eyes. At the time he vanished he was wearing an orange hooded sweatshirt with reflective tape and black sweatpants.

The family remains deeply concerned because of his medical needs and the lack of subsequent sightings or communication. If anyone has information about Jonas’s whereabouts, please come forward.
