The driver of an SUV that crashed into an MBTA bus in Saugus, Massachusetts on Sunday has died from her injuries.
MBTA Transit Police identified 47-year-old grandmother Kathleen Callahan as the driver of the Ford SUV that crashed into the MBTA bus at 3:50 p.m. near Essex and Felton streets.
The Route 429 MBTA bus was heading toward Lynn when it was hit head-on, investigators said. They said the SUV might have hit a parked vehicle, causing it to veer into the bus' lane of travel.
"She clipped the silver car and then all of a sudden started turning left. There’s no way the bus could stop. She just spun," said witness Taryn Medeiros, who was driving behind the SUV in her own vehicle.
"I could kind of see it coming when she started to veer right, so I started to slow down," Medeiros said. "I was like, 'I need to call 911. I don't think she's going to be OK.'"
All four passengers on board the bus and the bus driver were taken to local hospitals for minor injuries. No update on their conditions was available on Monday.
Other drivers stopped in the middle of the road to see if they could help at the scene.
Lenny Fauci said Callahan was unconscious when he checked on her and that she was by herself, "cause I checked the backseat to see if there were any children. I saw car seats. One car seat."
The cause of the crash remains under investigation, but authorities said they are looking into whether Callahan may have experienced a medical issue.
The accident happened about two blocks from where Callahan lived.
"She was a very eccentric person. She was very loud and boisterous, in a good way," said Del Correia, Callahan's manager at Dunkin' Donuts. "She was a lot of fun to work with."
