Collie was last seen around 9:30 p.m. on May 26, 2013, after dropping his brother off at the Job Corps in Guthrie, Oklahoma. He mentioned wanting to get home to rest before the work week began. Collie lived near 59th and Sunnylane in Del City, Oklahoma, but he never made it home and has not been heard from since. Collie was driving his orange 2007 Dodge Nitro at the time. On June 6, 2013, the vehicle was discovered abandoned and out of gas near Mount Hood in Hood River County, Oregon. The car was located near the Zigzag Trailhead, backed up to an embankment off Highway 35. Inside were Collie’s laptop, clothing, passport, and car keys. The front license plate had been removed and was found behind a seat. A search of the vicinity turned up no indication of his whereabouts. His case remains unsolved.
