6 people were stabbed in a restaurant and a cinema, including 4 girls. Now new details emerge about a suspect

A suspect accused of stabbing a man through the window of a McDonald's drive-thru and then stabbing a woman inside the restaurant was arrested last month on suspicion of assaulting a family member, according to court records.

Police in Massachusetts are also investigating whether the Plymouth McDonald's attacker also stabbed four girls ages 9 to 17 about an hour earlier at a movie theater in Braintree.

Jared Ravizza, 26, is the suspect in “several stabbing incidents on the South Shore,” the Plymouth County District Attorney's Office said, although no details were given about the other incidents.

Braintree police said it “appears” the attacks at the movie theater and McDonald's are linked.

Ravizza was arrested and faces charges of assault with intent to kill and two counts of assault and battery with a dangerous weapon in connection with the attack at McDonald's. The suspect is expected to appear in court Tuesday, and it was not immediately clear Monday whether Ravizza had an attorney.

Last month, Ravizza was arrested in Martha's Vineyard, charged with battery on a family member and vandalism, according to Edgartown District Court records. Records show the case has not gone to trial.

Ravizza's father told police that Jared “just had a mental breakdown and attacked him” inside his home, the Boston Globe reported, citing a police report filed in court.

The report also states that Ravizza allegedly destroyed the father's home office, according to the Boston Globe. Ravizza was sent to Martha's Vineyard Hospital for a mental health evaluation, but “did not meet the standards to be detained there,” the Boston Globe reported, citing the report.

How the weekend stabbings unfolded

The first attack took place around 6 p.m. Saturday at an AMC movie theater in Braintree.

“Without saying anything and without any warning, (the attacker) suddenly attacked and stabbed the four young women,” police said. “The attack appeared unprovoked. After the attack, the (suspect) ran from the theater and left in a vehicle.

The girls were transported to Boston hospitals with non-life-threatening injuries, Braintree police said.

The theater was closed shortly after the incident, an AMC employee told CNN.

The suspect fled the theater in what appeared to be a black SUV, and video footage allowed authorities to capture his license plate, authorities said.

A vehicle matching the description was allegedly “involved in (a) similar assault in Plymouth,” about 25 miles southeast of Braintree, police said.

About an hour after the movie theater stabbings, a 21-year-old woman and a 29-year-old man were stabbed at the McDonald's in Plymouth.

Ravizza allegedly arrived at the scene of the Plymouth McDonald's in a black Porsche Macan SUV, prosecutors said.

Surveillance footage from the McDonald's appears to show Ravizza climb through the drive-thru window and stab the male victim with a large knife, prosecutors said.

The video then shows the suspect park the car, enter the restaurant and stab the victim before fleeing in the car, the prosecutor's office said.

Both victims of the McDonald's attack were taken to the hospital with non-life-threatening injuries, authorities said.

Minutes after the McDonald's stabbings, state troopers located the suspect's car and attempted to stop him, authorities said. But the driver failed to stop and a chase ensued.

The suspect's vehicle ultimately crashed in Sandwich, about a 25-minute drive south of Plymouth, police said.

Ravizza was being treated for non-life-threatening injuries at the hospital Sunday, the prosecutor's office said.

While Ravizza faces assault charges in connection with the McDonald's attack, “preliminary investigation suggests a likely connection to an earlier incident at a movie theater in Braintree, resulting in non-life-threatening injuries of four juveniles in danger,” state police said.

It was not immediately clear whether Ravizza had an attorney. CNN has requested more information from the Massachusetts State Police, the Plymouth County District Attorney's Office and the Braintree Police Department.

Massachusetts State Police said the investigation is ongoing.

Investigators are looking into another possible link

In addition to the stabbings in Massachusetts, Connecticut State Police said a suspect in connection with a death in the town of Deep River was arrested in Massachusetts. But police in both states have not confirmed whether the Connecticut case is linked to the stabbings in Massachusetts.

Connecticut State Police said they responded Saturday afternoon to a “disturbance” at an address in Deep River. There, police found a “deceased person” whose identity has not been confirmed, Connecticut State Police said.

“A suspect in this investigation has been taken into custody in the state of Massachusetts and there is no active threat to the public,” Connecticut police said. Authorities have not named the suspect.
