Man Shot, Killed by Off-Duty Officer After Fatally Stabbing 2 and Driving Car Into Macy's

— -- A 28-year-old man was shot and killed at a Massachusetts shopping mall Tuesday evening, after he stabbed four people -- two of them fatally, Massachusetts State Police said Tuesday evening.

Two individuals were stabbed at Bertucci's Italian restaurant in Silver City Galleria Mall in Taunton, and two were stabbed at a nearby home, police said. Taunton is located about 40 miles south of Boston. One victim at the mall died, as did one victim at the home.

The assailant was identified as Arthur Darosa, by Bristol County district attorney Thomas Quinn III.

Darosa was shot at the mall by an off-duty deputy sheriff, Quinn said.

According to Quinn, the deadly set of events kicked off after Darosa was involved in a motor vehicle accident on Myrick Street in Taunton. Then, for reasons unknown, at a home on that street, Darosa stabbed two women: One of the victims, an 80-year-old woman, died. Another woman has life-threatening injuries.

Quinn said Darosa then got into a vehicle, drove to the shopping mall, drove through the front door of Macy’s, exited the vehicle, assaulted three people inside Macy’s, then went to Bertucci’s, where he stabbed two people. One of the victims, a 56-year-old man, died.

Tom Hoye, city's mayor, said "Tragedy has hit the city of Taunton hard tonight."
