AURORA, Colo. (AP) — Authorities are looking for a Wyoming man who went missing after moving to Colorado to become involved in the marijuana industry.

Aurora police spokesman Frank Fania said Friday that 50-year-old Carl Shull has been missing since Nov. 28, and investigators suspect foul play in his disappearance.

Shull, who was last seen in Aurora, may have been driving a Chevrolet S-10 pickup with Wyoming plates that he bought in the Casper area before moving to Colorado. Police do not know its color or the license plate number. He was traveling with his blue heeler dog named Bez.

Shull is white, 5-foot-10 and weighs 170 pounds. He has brown hair and blue eyes.

Fania says Shull has family in Nebraska, Kansas, Missouri and Wyoming.
