ONEONTA, N.Y. - Underground fraternities like the one where a freshman was found unconscious before dying from a combination of drugs and alcohol have been a longtime problem for the upstate New York college town, police said Tuesday.

Oneonta Police Chief Douglas Brenner said Daniel William Michaels, 18, of Dix Hills in Suffolk County, died of cardiac arrest after being brought to a local hospital in a private vehicle early Saturday. Michaels was found unconscious on a couch in the off-campus home of Alpha Pi, a frat that's not recognized by the State University of New York at Oneonta, Brenner said.

Someone called 911. But while officers were responding, Michaels was taken to a nearby hospital, where he was pronounced dead. Michaels died from cardiac arrest brought on by a combination of drugs and alcohol, the police chief said.

The Daily Star of Oneonta reported that Williams was a new pledge who was studying business economics at the school, about 135 miles (217 kilometres) northwest of New York City.

"We offer the condolences of the SUNY Oneonta community to Daniel's parents and family," college President Nancy Kleniewski said in a statement emailed to students Saturday. "We are all one community, and the death of a student is painful to us all."

An autopsy revealed a small amount of alcohol was found in his system, according to the Otsego County coroner. The amount of drugs detected won't be available until a full toxicology report is completed.

No one has been charged. The investigation was continuing Tuesday, police said.

Williams was found in an apartment in a rental home where two other frat members live, Brenner said. He said underground frats not recognized by a college have been a problem in Oneonta, home to the 6,000-student state school, and Hartwick College, a private school with an enrolment of 1,400.

"They're hard to track because they don't report to anybody," Brenner told The Associated Press. "We've had a long history of unrecognized fraternities that cause problems. They tend to come and to go."

WNBC-TV in New York reported that family members said the teen's twin brother, Justin, was killed when a tree fell on him at a day camp when he was 4 years old.
