Norwood Police say 55-year-old Cheryl Ann McCarthy of Dedham was crossing Broadway Street on her way to the train station when she was hit by an MBTA construction vehicle.

Convenience store employee Susan Eno says she saw the victim just minutes before the accident.

“I just heard something leaning on the horn and I saw the cars building up and I said, ‘I wonder if somebody got hit,'” Eno said. “And I turned the corner and she was on the ground.”

Eno works just steps away.

“She was just laying there and she was a mess,” said Eno.

“It’s tragic. It’s tragic for everybody involved and we’re trying to get to the bottom of it,” said Norwood Deputy Police Chief Peter Kelly.
