A Dunkin’ Donuts robber who was targeting several locations and is suspected in 20 assaults, was arrested with the help of GPS technology and an FBI surveillance plane.
Investigators used the tracking technology to help gather evidence against the alleged robber, who has been identified as Isaiah Murphy, 23 and charge him with two counts of robbery.
The Enterprise obtained court documents in the case, which indicate police believe the man is responsible for a string of attacks on several east Massachusetts Dunkin’ Donuts locations.
Police say there were 22 similar robberies at Dunkin’ Donuts stores, gas stations, and convenience stores in the past nine months.
A Judge issued a search warrant for Murphy’s home and police believe they have evidence that connects the young man to at least 15 of the robberies.
The latest Dunkin’ Donuts robberies took place on November 12 and 13, following two other attacks 24 hours earlier.
According to the court documents, prior to the search warrant, investigators got permission to install a tracking device on Murphy’s car.
Using the GPS and an FBI surveillance plane they followed Murphy, who seemed to be staking out several of the Dunkin’ Donuts locations that had been robbed.
The suspect seemed to be trying to throw police off his tracks and after being followed for about two-and-a-half hours, making several U-turns and driving into dead end streets, he was followed to an area of Boston in which he dumped clothes.
The FBI says the items are consistent to those shown of surveillance footage obtained at the Dunkin’ Donuts locations that were robbed, however they found no weapon.
When the search warrant for Murphy’s home was executed, police found a pair of shoes that matched those in the surveillance videos.
Police also found two rounds of.45-caliber ammunition and containers of BB pellets that are “consistent with the type of ammunition” the suspect seen holding several of the Dunkin’ Donuts robbery videos had.
Authorities say Murphy is a former Dunkin’ Donuts employee, which was evidenced by the extreme familiarity he showed in the assault of his former place of employment.
His 2004 Acura TL matches descriptions of a getaway car seen by witnesses and on surveillance video at one of the robberies, which has dark, tinted windows and custom New England Patriots license plate.
Video of the Dunkin’ Donuts robberies show Murphy using calm language and discussing how poorly the company pays its employees.
