Summary based on the NamUs case record (MP15674) and 1 other source
On the first day of the new year, January 1, 2001, a young man named Alejandro Mariscal vanished from Tucson, Arizona. At just 19 years old, the Hispanic / Latino male was at the beginning of his adult life. The circumstances surrounding his last known whereabouts are shrouded in mystery, as detailed information regarding the specific events of that day is not publicly available. His case is documented with the Pima County Office of the Medical Examiner, but the available records offer scant details about his life or the events that led to him being reported missing.

Efforts to piece together a narrative of Alejandro's disappearance are hampered by the limited information that has been made public over the years. Details regarding his clothing, what he was doing, or who he might have been with at the time he went missing have not been widely circulated in the available online sources. This lack of public information creates a challenging environment for generating new leads or for the community to provide meaningful assistance. The passage of time has further complicated the situation, pushing his case into the background as more recent events take precedence.

Over two decades have passed since Alejandro Mariscal was last seen, and his case remains an unresolved and poignant mystery. The official investigation, as noted in public databases, provides no specific circumstances of his disappearance. Without witnesses, a defined timeline of his last movements, or any significant evidence, the case has grown cold. The overview of this case is one of a sudden and unexplained absence, a young man who disappeared without a trace, leaving a void of information and unanswered questions for his family and community.
