Thomas John Manzey, 56, was last seen by family on December 24, 2023, after abruptly quitting his job the day before. He was reported missing on January 17, 2024. Authorities in Arizona made contact with him in January 2024, but no further communication has been established since that contact. He was last known to be in Phoenix, Arizona, though the Sioux Falls Police Department in South Dakota is the primary investigating agency, suggesting a connection to that area.

Manzey is a white male, 6 feet tall, about 200 pounds, with gray or partially gray hair and blue eyes. He has been seen with a long gray full beard or a goatee.

If anyone saw Thomas in late December 2023 or January 2024, or has information about his movements between South Dakota and Arizona, please share what you know.
