On June 21st, 2004, 43-year-old Jim Donnelly signed into work at the Glenbrook Steel Mill. 16 years later, Jim still hasn't signed out. Despite a wide-ranging search, and investigation of Jim's personal life, there is very limited evidence as to what happened to him, leading to plenty of speculation and unique theories about his disappearance. To this day, Jim's family is no closer to finding out what happened, and without new evidence or witness information, they may never know.
