Sean Ryan Gribble, 30, was last seen May 20, 2014, at his mother’s home in Wheat Ridge, Colorado while on a work-release program from the Denver County Jail. He failed to return to the correctional facility as required that day and has not been seen or heard from since. Family members reported him missing and the Wheat Ridge Police Department opened an investigation.

Sean is described as a white male, about 6 feet 1 inch and 180 pounds, with blond hair and blue eyes. Distinguishing features include piercings in both ears and his nipples and a prominent tattoo on his right arm of a Celtic tribal band containing his initials SRG. He had been suffering from depression and was considered suicidal at the time he vanished. Few leads or details about his last movements or state of mind that day have been reported, and the case remains open and unresolved.

If anyone knew Sean, saw him around May 20, 2014, or has information about his whereabouts, please come forward.
