Summary based on the NamUs case record (MP39072) and 3 other sources
In the early spring of 2002, the life of a young man from Tucson, Arizona, took a turn into bewildering uncertainty. Benjamin Carlisle Tallmadge, a 23-year-old male known to friends and family as Ben, was last seen on March 21, 2002. On that day, his father provided him with a ride, dropping him off at a residence in the vicinity of Ina Road and Interstate 10. This location would become the last place anyone has confirmed seeing him. At the time of his disappearance, Benjamin stood at 5 feet 9 inches and weighed around 160 pounds, with brown hair and brown eyes. What was intended to be a simple drop-off has since become the starting point of a mystery that has endured for years, leaving his loved ones in a state of prolonged anguish.

The details surrounding Benjamin's plans on that particular day remain vague and largely unknown to the public. There has been no contact from him since the day he was last seen, and information regarding who he was planning to meet or what his intentions were has not been forthcoming. This lack of information has created significant challenges for those trying to piece together the timeline of his last known movements. The official report of his disappearance was filed with the Tucson Police Department on October 31, 2002, several months after his last contact with his family, adding another layer of complexity to the initial investigation.

Over the years, the search for answers in Benjamin Tallmadge’s case has unfortunately yielded very few leads. The passage of time has not diminished the hope held by his family, but it has made the task of uncovering new information increasingly difficult for law enforcement. An overview of the case reflects a heartbreakingly common story in missing persons investigations: a young person vanishes with scarcely a trace, leaving a family to navigate a world of unanswered questions and a community to ponder the circumstances of his disappearance. The case is a somber reminder of how quickly a person can disappear and the profound and lasting impact such an event has on everyone involved.
