Police in two jurisdictions are investigating incidents from Wednesday night where descriptions of the suspects are similar.
Westville police are investigating an attempted armed robbery at the Dairy Queen at 56 S. Flynn Road, just before 9 p.m. Valparaiso police are investigating an armed robbery of the Subway at 1710 Lincolnway at 10:23 p.m.
In the Westville attempted robbery, Town Marshal Darin Mercer said the store was closed when the gunman walked in. Employees had stopped accepting customers, but failed to lock the door the suspect entered while they were preparing to close for the night.
He displayed a gun and demanded money. Police said an employee was heading to the back to the store to retrieve the keys to the registers when the man fled.
"It looks just by the appearance of the video like the suspect was definitely nervous. He waited only for a second or two and fled," Mercer said.
In the Valparaiso incident, police said a man entered the business, displayed a handgun and demanded money from the cash register. He fled after taking an undetermined amount of money.
The suspect in both incidents is described as a black male, 6-feet 3-inches tall, wearing black sweatpants and a white T-shirt with a black sweatshirt. The description from the Valparaiso police estimates the suspect weighs about 180 pounds and was between 30 years and 40 years old. Mercer described the suspect as thin.
Mercer said his department will work with police in Valparaiso to see if there's a connection.
Valparaiso police spokesman Sgt. Mike Grennes said they will "look into every possibility," but have not come to any conclusions to determine if it is the same suspect or different individuals.
Anybody with information on the Valparaiso armed robbery is asked to call Detective Lt. Tom Horn at the Valparaiso Police Department at 219-462-2135.
