Sergio Bravo Ayala, 44, disappeared from Murphy in Owyhee County, Idaho, on July 24, 1995. At the time he was a federal witness preparing to testify in an upcoming trial and had received several threatening phone calls in the weeks before he went missing. Investigators consider him endangered and strongly suspect his disappearance is connected to those threats.

Ayala is described as a Hispanic male with black hair, brown eyes, a tattoo on his left forearm and a gold tooth. He was last seen in Owyhee County and has not been heard from since; despite the passage of time no significant leads or evidence have surfaced and the case remains unsolved.

Anyone with information about Sergio Ayala’s whereabouts or the threats he received is asked to contact the Owyhee County Sheriff’s Office.
