Moments after Monday's crash, video from Sky 5 showed a large hole in the glass front of the store. There were multiple people on the ground outside the store being tended to by the dozens of first responders at the scene. Twenty patients were treated at South Shore Hospital, Brigham and Women's Hospital and Boston Medical Center. "This morning was an unthinkable morning, and people are trying to get through it and process what happened," Cruz said. "This investigation is active and ongoing." The store opened at 10 a.m. on Monday, and the crash happened less than an hour after it opened.Cruz said it wasn't clear how many people were inside the store at the time."Really... absolute unthinkable event that occurred at that store when you're just going there to buy a phone or get something fixed or whatever it may be, it's absolutely unthinkable," Cruz said.A tow truck removed the SUV from the store just after 3 p.m. Monday.In a statement, Apple said the victim that was killed was a construction worker."We are devastated by the shocking events at Apple Derby Street today and the tragic loss of a professional who was onsite supporting recent construction at the store," Apple said in a written statement. "Our hearts go out to our team members and customers who were injured and all of those who were affected by this terrible incident." South Shore Health said they were treating 17 patients for injuries ranging from head trauma to limb injuries."We have multiple patients with life-threatening and limb-threatening injuries," Dr. Christopher Burns, chief of trauma for South Shore Health, said. "We have patients in the operating room and people we anticipate going into the operating room."South Shore Health said all patients were reunited with family members or loved ones."We got a hysterical phone call. One minute, it's just a routine day at work. Next thing, a car comes crashing through the building," said John Dinanno, whose daughter was injured in the crash, transported to South Shore Hospital and released from the hospital Monday night. "We're just relieved that she's going to be OK. I just thank God that she's fine. Just something to be thankful for as we're getting closer to Thanksgiving.""She was hit and she said that she had a broken bone, and she had cuts and scrapes all over her. She's just hurting really bad," said Susan Gamble, whose niece was transported to South Shore Hospital after the crash. "In fact, last night, she went there and she forgot her wallet and she had to go back today — and then this happened." Crime tape blocked off a large area of the parking lot surrounding the Apple store. A witness said the driver appeared to be injured, but alert, following the crash. Frank O'Brien, who was shopping at Derby Street at the time, told the Patriot Ledger he wondered how fast a car would have to go to bust through the glass in front of the store."You'd have to really be picking up speed to end up in the storage area at the back side of the Apple store," he said.One person who was inside the store at the time of the crash said the SUV appeared to be moving at a high rate of speed when it crashed into the store."It was like a big explosion," another witness, who was outside, said. "It was so loud."A man who spoke with NewsCenter 5 said his friend was in the Apple store at the time of the crash and that she estimated the car was traveling about 50 mph when it came through the front of the building."That was her guess," he said.Cruz would only say that the SUV was traveling at an undetermined speed when it crashed into the store."Regarding the operator of the motor vehicle, we're looking into that," Cruz said. "Regarding the status of the motor vehicle, we're looking into that. Obviously, we're going to get the information we can and go forward.""We are devastated by tragedy and are grateful to our on-site team and to the South Shore’s first responders for their immediate attention," Derby Street Shops said in a statement on social media. "Our hearts go out to the victims, their families and our Derby Street community."Derby Street Shops at 92-98 Derby St. in Hingham, are a collection of 64 stores and restaurants.
