The Cass County Sheriff’s Office is investigating an armed robbery of the Marathon gas station on M-60 east of Jones, which was robbed at approximately 2:45 p.m. Dec. 10.

An armed gunman entered the store demanding money from a cashier behind the counter. After this the suspect fled the scene, employees at the store were able to obtain a description of the vehicle and direction of travel.

On Friday, at approximately 10:30 p.m., the same cashier was working when they noticed a suspicious vehicle matching the vehicle involved in the robbery from two days prior and immediately called 911 to report the situation while a customer confronted a subject in the parking lot hiding near the corner of the store.
