HANOVER, N.H. (AP) — A sorority at Dartmouth College and two members of a fraternity are facing charges related to the death of a student who drowned after attending an off-campus party this summer.

Won Jang, 20, of Middletown, Delaware, had been reported missing in July after the party. State and local emergency responders searched the Connecticut River and found his body.

On Friday, police in Hanover, New Hampshire, where Dartmouth is located, announced that Alpha Phi has been charged with one count of facilitating an underage alcohol house. Two members of the Beta Alpha Omega were charged with providing alcohol to a person under 21.

The party was hosted by Alpha Phi sorority and alcohol was provided by Beta Alpha Omega. Most of those at the party were under 21. At the end of the party, police said several attendees decided to swim in the river. While at the river, a heavy rainstorm hit and most people left. Jang, whose family told authorities he could not swim, was left behind.

At the time of the incident, Dartmouth suspended the sorority and fraternity and those suspensions remain in effect. Jang was a member of Beta Alpha Omega.

“Dartmouth has long valued the contributions that Greek organizations bring to the student experience, when they are operating within their stated values and standards," the college said in a statement. "These organizations, as well as all Dartmouth students and community members, have a responsibility to ensure Dartmouth remains a safe, respectful, equitable, and inclusive community for students, faculty, and staff.”

No one from Alpha Phi could be reached for comment.
