Jeff Walter Terzian, 64, was last seen in Pueblo, Colorado, with his official last-seen date listed as August 1, 2023, though the exact date of disappearance is uncertain. Concern grew when his phone stopped showing activity in the first week of August 2023, a break in communication that was out of character and prompted family and the Pueblo County Sheriff’s Office to open an investigation.

Jeff is described as a white male, about 6 feet tall and 150 pounds, with brown hair and brown eyes. The case went cold after investigators found no witnesses, forensic evidence, or clear leads; months became a year without new information and the investigation remained open as of early 2025.

This is a quiet but unresolved disappearance centered on the sudden cessation of contact rather than a specific known event. If anyone in Pueblo had contact with Jeff around late July or early August 2023, or saw him or his vehicle, please share what you know.
