BOSTON - Boston University has suspended a fraternity as police investigate the death of a 19-year-old member from New Hampshire.

Tony Barksdale II, a freshman who graduated from Souhegan High School in Amherst, N.H., last year, was rushed to the hospital after being found unconscious in an off-campus apartment early Saturday. He died a few hours later.

Boston University Dean of Students Kenneth Elmore told university website BU Today that the Sigma Alpha Mu chapter's suspension followed "reports of underage drinking and severe intoxication" at an unregistered off-campus fraternity event.

Elmore said the fraternity's national organization has also suspended the BU chapter after the death of Barksdale.

"We need to find out what happened on Friday evening and determine if there was a policy violation and how bad that violation may have been," Sigma Alpha Mu national executive director Leland Manders told BU Today. "We will work in partnership with the university offices to determine if the chapter can continue in the future and under what circumstances it continues."
