A surveillance image of the car believed to have been driven by the suspect in the Wethersfield robbery Friday.
The suspect who followed an elderly woman home from a grocery store and robbed her last week in Wethersfield may have committed similar crimes in two other towns.
The woman called police at 10:52 a.m. on Friday to report the robbery.
She said a man followed her from the Stop & Shop on Town Line Road in Rocky Hill to her home on Pine Lane in Wethersfield and robbed her at gunpoint in the garage when she got out of her car. She said the man took cash and her debit card.
The incident was similar to two others that occurred in Berlin and New Britain, according to police. An elderly woman in Berlin said a man followed her home from a Stop & Shop in Newington and robbed her at gunpoint. In New Britain, a 90-year-old woman reported she was followed from the Stop & Shop to her New Britain home. The suspect pulled a gun on her and robbed her, police said.
Detectives from all three police departments are working together to solve the robberies.
"We are working together, sharing this information. We have also shared this information with other police departments so they can be vigilant and also if any other incidents happened that we may not be aware of," said Chief Paul Fitzgerald, of the Berlin Police Department.
In all three cases, the suspect was described as a black male between 35 and 40 years old, driving a white Chrysler 300 with Connecticut plates.
