BOSTON (MyFoxBoston.com) -- A Winthrop man accused of threatening to kill everyone inside a Dunkin' Donuts during a December 2013 robbery reportedly dropped his cell phone at the crime scene.
Dennis Stack was arraigned in Charlestown District Court this week on an armed robbery charge stemming from the Dec. 10 robbery.
Investigators allege Stack ordered an employee at a Dunkin' Donuts on Cambridge Street in Boston to hand over gift cards and cash. Stack claimed he was armed and threatened to kill everyone inside the eatery, police say.
Stack reportedly attempted to climb over the counter, at which time a customer grabbed him and a struggle ensued. During the struggle, police say Stack dropped a tire iron and an iPhone before fleeing with $65 from the register.
Boston police saw several text messages and calls come in on the cell phone's screen. They were able to call one of the numbers and the individual identified Stack as the phone's owner.
Stack is accused of committing at least four robberies in Suffolk County. Bail in those cases range from $10,000 to $75,000. He also faces additional robbery charges out of Middlesex County.
The 41-year-old was held on $15,000 bail in the Dec. 10 case. He is due back in court on March 24.
