Armed Robbery Suspect: From surveillance footage at a Shell gas station in South Boston on March 29.A rash of armed robberies of convenience stores — including three in Dorchester’s C-11 police district in recent days—is prompting a Boston Police alert this afternoon.

The most recent robbery took place on Monday, when a white Hispanic male flashed a gun at a worker inside the CVS store on Morrissey Boulevard. The incident took place at about 2 a.m., according to Captain Richard Sexton, commander of the C-11 police district.

Gerard’s Adams Corner store was robbed on Saturday, April 2, just after it opened for the day around 5:30 a.m. A third Dorchester store— the 7-11 gas station on Morrissey Boulevard, was also hit on March 20— apparently by the same gunman that was caught on tape on Monday robbing the CVS across the street.

Armed Robbery at CVS: Robbed store at gunpoint on April 4.Based on surveillance images, investigators believe that the same man is likely responsible for at least two of the hold-ups, which targeted local stores during early morning hours.

“What we’ve seen is one suspect in the store, who gets them to open the register with a means of purchasing something and then he makes his move, displaying a firearm,” Sexton told the Reporter.

Sexton said Boston Police are also seeing similar store robberies in other police districts and outside of the city.

The suspect is described as a white Hispanic male with facial hair or a goatee. In two different surveillance images he is shown wearing a black puffy vest with black long sleeve undershirt and a black baseball hat.

Captain Sexton said that Boston Police had made an arrest recently after the armed robbery of the Hess gas station on Gallivan Boulevard on March 3. It is not clear yet if that incident is related in any way to this more recent rash of hold-ups.
