Mark William Bishop, 43, was last known to be in Burnham, Illinois, in June 2003 after the recent death of his father. Details about his last known movements are sparse: there is no public information about what he was wearing, whether he had any personal items, or if he left by vehicle or on foot. He is described as a Black man between 6 feet 1 inch and 6 feet 3 inches tall, weighing about 210 to 220 pounds, with black hair, brown eyes, and a mustache and goatee.

The Burnham Police Department continues to handle the open case. Investigators have pursued leads and obtained DNA samples from his siblings to assist identification efforts. The family remains without answers about what happened after his father’s death. If anyone in Burnham or the surrounding area remembers seeing Mark in June 2003 or has information that could help, please come forward.
