Summary based on the NamUs case record (MP21004)
In the autumn of 2012, a family's life was forever altered when Mark Devine Coley, a 33-year-old man, vanished from Rochester, New York. He was last seen on October 11, 2012, and the circumstances surrounding his disappearance remain shrouded in mystery. At the time he went missing, Mark was described as a Black / African American male, standing between 5'3' and 5'5' tall and weighing approximately 140 to 145 pounds. He had black hair and brown eyes. When he was last seen, it is believed he was wearing black jeans and a white T-shirt. A light mustache was noted as a facial feature, and he was also known by the nickname 'Theory'.

The Rochester Police Department opened an investigation into Mark's disappearance, assigning it case number 12-337138. Despite the passage of years, the case has grown cold, with no significant leads or confirmed sightings to bring clarity to his whereabouts. The lack of substantial developments has left his loved ones in a painful state of uncertainty. Law enforcement and his family have continued their search for answers, holding out hope that new information will surface. Public assistance is considered crucial in the effort to uncover new leads that might shed light on what happened to Mark.

Mark Coley's case is a somber reminder of the many unresolved missing persons investigations that challenge communities and law enforcement agencies. The official report of his disappearance was filed on October 27, 2012, more than two weeks after he was last seen. The case was entered into the National Missing and Unidentified Persons System under case number MP21004. The investigation has seen the collection of DNA from family members to aid in potential identification efforts. Despite these measures, the fundamental questions of where Mark is and what occurred on that October day remain unanswered. The case underscores the enduring struggle for families seeking closure and the persistent efforts of investigators working to solve long-standing mysteries.
