Summary based on the NamUs case record (MP2398) and 8 other sources
In the late evening of October 24, 2006, Mark Randall Johnson, a 42-year-old resident of Tolland, Connecticut, walked out of his home on Cider Mill Road and vanished. He was last seen between 11:00 and 11:25 p.m. leaving his residence on foot. Johnson departed without his cellular phone or a vehicle, stepping out into the night wearing a dark-colored coat, jeans, a gray long-sleeved shirt, and dark rubber snow boots. His wife, Donna-Lee Maheu-Senk, reported him missing to the Connecticut State Police at approximately 11:25 p.m. She expressed concern, noting that he had a medical condition and seemed depressed over personal issues. The immediate search of the area by law enforcement, which included K9 teams and a State Police helicopter, yielded only one clue: his sheepskin hat was found nearby, but there was no other trace of him.

The investigation into Mark Johnson's disappearance uncovered a complex personal life. He had married just a few months prior to going missing. His wife claimed that Johnson contacted her several times in the months after he disappeared, suggesting he may have left voluntarily because he feared going to prison. Johnson had a pending legal issue from a 2004 arrest for possession of drug paraphernalia and had missed subsequent court appearances. His wife believed he was on probation and may have not complied with the terms, leading him to flee. However, Johnson's lawyer stated that he was not in any danger of being incarcerated. Police were never able to verify his wife's claims that he had made contact with her. It was noted as uncharacteristic of him to be out of touch with his family, with whom he maintained regular contact, particularly his stepson whom he visited weekly in a juvenile detention facility.

Despite extensive searches and ongoing investigative efforts by the Connecticut State Police, Mark Johnson has never been found, and no contact has been confirmed with any family or friends since the night he went missing. The circumstances of his case remain ambiguous, with conflicting information about his state of mind and the possibility of a voluntary departure. The lack of evidence and communication has left his loved ones without answers for years. In October 2010, at the request of his sister, Mark Randall Johnson was declared legally dead. His case remains an unsolved and active missing person investigation, a painful lingering mystery for his family and the community.
