The station says that on Tuesday morning, officers from several agencies, including Canton and Boston police and the FBI, arrested 23-year-old Isaiah Murphy at his Dedham home south of Boston.
A $10,000 reward had been offered for information leading to the arrest and conviction of a suspect.
According to CBS Boston, Dunkin’ Brands released a statement saying they were grateful an arrest has been made.
“We are working with the Canton PD to determine if a tip led to the arrest of the suspect,” a spokeswoman said in a statement. “If not, we intend to donate the reward.”
