The same 7-Eleven convenience store in Naperville has been hit by an armed robber twice in one week and authorities say the same man may be responsible for both.
The robberies, which occurred at 10:07 a.m. Thursday and 7:21 a.m. May 15, appear to be related, police said. Both occurred at the 7-Eleven at 351 E. Bailey Road.
In the first robbery, a suspect described as a white or Hispanic man wearing a ski mask, a black coat and black and white gym shoes made off with an undisclosed amount of cash from the register, Sgt. Bill Davis said.
The description of the suspect in the second robbery is similar, and Davis said police think the same person might have been responsible in both cases. No arrests have been made.
The man who fled with an unknown amount of money Thursday morning is described as white, about 30 years old and unshaven with brown hair. Witnesses told police he was wearing a gray hooded sweatshirt, blue jeans and white and black gym shoes with a red mask covering part of his face.
Police said the suspect in the second robbery implied he had a weapon but did not show one. Davis said police are canvassing the area and speaking with other potential witnesses as they continue their investigation.
Investigators have called into service the department's newest of three K-9 units, including a Belgian Malinois/German shepherd-mix named Maximus, to follow the suspect's trail after both reported robberies.
In the first case, Maximus led investigators to an apartment complex, but they were unable to find the suspect. Davis said he did not yet know where Maximus led investigators Thursday.
Police are looking into a possible suspect vehicle -- a dark green, older model Volkswagen Jetta with a tan roof -- that was seen near the 7-Eleven around the time of the second robbery. Davis said that vehicle was not seen around the first robbery, but the suspect might have used it to get away after the second.
Anyone with information about the robberies is asked to contact Naperville police at (630) 420-6664 or Crime Stoppers at (630) 420-6006.
