An Arizona inmate is on the lam after failing to return to jail from a work release program, prompting a nationwide manhunt. According to the FOX 10 Phoenix, the Yavapai County Sheriff's Office reported that Trevor Trammel did not come back to the Camp Verde Jail after being granted temporary leave on May 1.

The Sheriff's Office launched an immediate search after Trammel's absence was noted. Officers were unable to reach him by phone, and his employer confirmed that the contact information they held was up to date. According to the Arizona Daily Independent, deputies pursued leads at all known addresses associated with Trammel but to no avail.

Information from a witness, who observed Trammel leaving with his girlfriend in an older-model white Toyota 4Runner with a broken windshield, has redirected the investigation. "This person stated that Trevor left with his girlfriend and had talked about plans to go to Michigan," YCSO disclosed. The tip has spurred conjecture that the escapee may be heading out of state.

A nationwide warrant has been issued for Trammel's arrest on suspicion of second-degree escape. Yavapai County authorities are asking for the public's assistance in locating the fugitive. Anyone with knowledge concerning Trammel's whereabouts is urged to contact the YCSO at 928-771-3260 or to provide information anonymously to Yavapai Silent Witness at 1-800-932-3232. As the search continues, local and national law enforcement remain on high alert for any sign of the missing inmate and his girlfriend.
