Authorities also say that two more people may be related to the stabbing deaths of a 29-year-old man and a 21-year-old woman that occurred in a McDonald’s restaurant.
The identification of the individual who was taken into custody after a car chase that resulted in a collision in Sandwich, Cape Cod, has not been made public.
About 6 p.m. local time on Saturday, according to the police, a man entered one of the movie theaters at the AMC Braintree 10 complex, which is located south of Boston, without paying.
The Braintree police department released a statement saying, “He suddenly attacked the four young females without saying anything and without any warning.”
