Police in Braintree, Mass. said a man entered the AMC Braintree 10 around 6 p.m. Saturday, walked past the ticket counter, went into one of the theaters without paying and stabbed four young girls in an unprovoked attack. The girls, who range in age from ages 9 to 17, were being treated for non-life threatening injuries.
After the stabbing, the man reportedly ran out of the theater and drove away in an SUV. Video surveillance of the man's vehicle captured the license plate and helped officers look for it.
According to authorities, the man was then involved in another stabbing at a McDonald's at a Park and Ride in Plymouth, Mass. shortly after. A 21-year-old woman and a 29-year-old man were taken to the hospital to be treated for non-life-threatening injuries.
