The Gallatin County Sheriff's office is looking for the public's help in finding the suspect who they believe robbed the Casey's Corner Gas station in Four Corners back on November 26, 2016.

The suspect walked through the store and into the bathroom where he remained until the store was empty of patrons. The suspect then dawned a ski mask seen on his head and detained the store clerk in a back room with two 12-inch kitchen knives.

They believe the suspect was in the store over 15 minutes until the crime was complete. The suspect exited the back of the store when a patron entered. Law enforcement believes the suspect ran past the Carriage House Car Wash and or Summit Motor Sports to an unknown location/vehicle.

Below are pictures captured that night of the suspect.
