OSCEOLA COUNTY - Police are searching for a man who robbed a Marion gas station on Sunday while wearing a mask reminiscent of a horror film murderer. Michigan State Police troopers from the Mount Pleasant post were dispatched to the Marion Shell gas station around 10 p.m. on Sunday after a man wearing white plastic hockey mask entered the store, produced a large, shiny knife, and demanded money and cigarettes. The store clerk gave the thief money from the cash register and safe, as well as 12 cartons of cigarettes. The thief was observed exiting the store and running to the west down main street by an eyewitness, who was standing outside of the gas station. Police believe the suspect ran to a vehicle and left the scene. The suspect was described as a white male, approximately 5 feet to 5 feet 5 inches tall. He was dressed in a black or dark jacket and was wearing blue jeans. His hockey mask was similar to that worn by fictional murderer Jason Voorhees in the movie "Friday the 13th," with black tear drops drawn on sides of eye holes. Troopers were assisted at the scene by members of the Osceola County Sheriff's Department as well as Marion Police officials. Michigan State Police Sgt. Joshua Lator said the department has received several tips about the suspect, but nothing conclusive. "We have had some calls, and the calls we've had we're following up on," he said. Anyone with information regarding the incident or suspect is encouraged to contact troopers at the Mt Pleasant Post at (989) 773-5951.
