DEDHAM (CBS) – A school community in Dedham is mourning Monday after the sudden and shocking death of a 16-year-old student on the playing field.

Junior Casey Dunne had just started field hockey practice with her teammates at the Noble and Greenough School on Friday when suddenly she collapsed just seconds after telling her friends she didn’t feel well.

She died of an apparent brain hemorrhage shortly after a photo was taken of her holding an American flag. Her mother, Mary Dunne, says the photo gives her strength.

“It totally embodies Casey,” she told WBZ-TV. “She was pure joy, and the thing about that picture is it was taken a half hour before she collapsed and for me it acts as a source of comfort because I knew that she was happy. She was with the people that she loved: her team.”

Casey, of Wellesley, served as a tutor for low-income middle school students, and the school is accepting donations in her memory to benefit the program.

“The Nobles community is devastated at the loss of a vibrant, generous and joyful member of our community,” the school said in a statement.

Counselors were on hand Monday to support grieving students and teachers at the school, where Dunne’s parents both worked.

Visiting hours for Dunne will be from 4-to-8 p.m. Wednesday at George F. Doherty and Sons Funeral home on Washington Street in Wellesley. A funeral will be held at 10 a.m. Thursday at St. Paul Church in Wellesley.
