Police are looking into whether hazing played a role in the death of a Dartmouth College student whose body was found in a river over the weekend.

Won Jang, a member of the class of 2026, was reported missing Sunday afternoon after last being seen at a social gathering the night before, at docks near the Connecticut River. Police searched the area with the help of a dive team, fish and game officers, and marine patrol. Several hours later, they found Jang’s body in the river approximately 65 feet offshore, according to a media release from the Hanover Police Department in New Hampshire.

Jang, 20, was a biomedical engineering major from Middletown, Delaware, who “enthusiastically took part in the Dartmouth community,” Dartmouth’s Dean of the College Scott Brown said in a statement offering condolences to the community.

Two friends of Jang wrote in an email to The Dartmouth, the college’s student newspaper, that Jang had attended a joint event the night of July 6 between his fraternity, Beta Alpha Omega, and Alpha Phi, a sorority. The event had involved alcohol, the two friends said.
