Mark Allen Miller, 48, disappeared after finishing his shift as a senior banquet captain at the Clock Tower Resort and Conference Center in Rockford, Illinois, on March 12, 2009. That evening he told a friend he planned to ask his roommate of two years to move out; he later called to say the talk had gone better than expected. His roommate, Manuel Vasquez Rivera, is believed to have been the last person to see him.

A few days after Miller was last seen, his silver 1998 Chrysler New Yorker was found abandoned in the 1900 block of Harlem Boulevard, about a mile from his home on Whitman Avenue. Searches of the car and his apartment showed no signs of a struggle and turned up no immediate clues. His briefcase and car keys have never been recovered.

In October 2012 ATV riders found Miller’s wallet at the Rocky Glen Off-Highway Vehicle Park; the pocket where it was found also produced human remains, but those remains were later determined not to be Miller’s. His parents in Eau Claire, Wisconsin, and his four brothers remain without answers. The Rockford Police Department continues to investigate.

If anyone knew Mark’s movements on March 12–15, 2009, or has information about Manuel Vasquez Rivera’s whereabouts after that time, please share what is known.
