BOSTON-Scott Krueger, the 18-year-old Massachusetts Institute of Technology first-year who went into a coma after suffering from serious alcohol poisoning at a fraternity party Saturday, died last night at Beth Israel Deaconess Medical Center.

Krueger's cousin William W. Burke-White '98 said last night that Krueger's mother had called him to pass on the news of her son's death.

Krueger's parents and siblings were seen leaving the hospital last night at approximately 9:30 p.m.

Krueger had been in the intensive-care unit since Saturday night, when he was rushed to the hospital with a blood alcohol level of 0.41, five times the legal driving limit, according to Dr. Richard Schwarztein, the attending physician at the intensive care unit last night and an assistant professor of medicine at Harvard Medical School.

"If someone were drinking relatively quickly over a period of time, it would be about ten beers, on that order, perhaps," said the doctor, who declined to comment on Krueger's death.

"The family's requested that we not give out any information about their son until later today," Schwarztein said. "We're just trying to abide by their wishes at the moment."

Krueger consumed the fatal doses of alcohol at the Phi Gamma Delta fraternity house at 28 The Fenway in Boston during a celebration held for new members of the Greek society.

It was Krueger's fourth week at MIT.

According to Burke-White, Krueger's parents chose to take their son off life-support yesterday afternoon when doctors told them he was clinically brain dead.

"The doctors advised the family that Scott would pass away even with life-support in the near future and this was the humane way to proceed," Burke-White said.

Reached yesterday after Krueger had been taken off life-support, Iddo Gilon, an MIT senior and president of the school's InterFraternity Council-which governs the school's 39 Greek societies and independent living groups-said the event is sending shock waves across campus.

"The atmosphere is very grim," Gilon said. "This incident has hit across a large portion of the student body and rightfully so. People are taking this with the utmost seriousness."

In response to the weekend's tragedy, Gilon said the council on Sunday night approved a complete ban on alcohol at the Greek societies and off-campus housing.

The MIT chapter of Phi Gamma Delta, Krueger's fraternity, has been suspened by both the school and by its national organization. Officials at the national headquarters in Louisville, Ky., could not be reached last night.

"Residents are able to live there but [they] cannot conduct any activities under the Phi Gamma Delta name," Gilon said.
