A Massachusetts Institute of Technology freshman pledge lapsed into an alcohol-induced coma after a fraternity party, prompting the school to suspend the Phi Gamma Delta chapter.

Scott Krueger, 18, of Orchard Park, N.Y., was in critical condition Sunday at a hospital where paramedics took him early Saturday.

His parents said the teen’s blood-alcohol level reached .410 percent - five times the legal limit for drivers in Massachusetts. Darlene Krueger said her son attended a fraternity function before losing consciousness.

“They told me it was a party where little (fraternity) brothers were paired off with big brothers,” Darlene Krueger said. “The freshmen had to drink a certain amount of alcohol collectively.”

Vomit and empty liquor bottles were found in Krueger’s frat house room, Boston police said.
