CAMBRIDGE, Mass. — A Massachusetts teacher who was hit by a car Sunday has died of her injuries.

State police say 31-year-old Molly Doub died early Wednesday. She was hit Sunday while trying to cross a street in Cambridge.

The International School of Boston says Doub was a high school math teacher. She joined the school two years ago after working in her home state of Connecticut.

Police say she was hit by a car driven by a 56-year-old Boston man. It has not been determined if he will face criminal charges.
