Casey Schulman, a J.E.B. Stuart High School graduate in her fourth year at the University of Virginia, died this weekend after a boating accident in the Caribbean.

Schulman had been taking part in Semester at Sea, a study abroad program in which students live and study aboard a boat while traveling across the globe.

The Associated Press reports that the 22-year-old and some fellow students were on a snorkeling trip on the Caribbean island of Dominica Saturday when the incident occurred. Schulman was swimming near their hired boat when the boat drove in reverse and she was struck by its propellers; she was later pronounced dead at an area hospital, according to AP reports. The trip was organized independently of Semester at Sea.

“We wish to convey our condolences to Casey’s family, her many friends, and those who witnessed the accident,” Semester at Sea President Les McCabe said in a statement on the program’s website. “Please join me in keeping the Schulman family in your thoughts at this very difficult time.”

According to The Cavalier Daily, the University of Virginia’s student newspaper, Schulman was a Foreign Affairs major and a member of Alpha Phi sorority who was active in tutoring and intramural sports. At Stuart, she was a cheerleader and swim team member. She graduated with the Class of 2009.

“On behalf of all members of the school staff and students, our deepest condolences are with Casey’s family and friends during this difficult time,” said Stuart Principal Prosperanta B. Calhoun in a statement emailed to the Stuart community. “Casey is remembered by many Stuart faculty as a young lady who warmed the hearts of everyone who knew her and she will be missed by us all.”

A service in Schulman’s honor was held Sunday evening and the Semester at Sea boat is scheduled to return to Florida on Friday, according to McCabe’s statement.
