Sad news for the University of Virginia. Senior Casey Schulman was killed Saturday while in the last leg of her Semester at Sea program, when a boat backed into her while she was swimming. The 22-year-old was set to return home this week. The accident happened at the ship’s final stop on the island Dominica. Several students were in the water snorkeling at the time, but police said Schulman was the only one hit by the propeller.
