BOULDER, Colo. -- Boulder police have released a tape of the 911 call for help from the Chi Psi fraternity house where an 18-year-old freshman pledge was found unconscious and barely breathing on the floor.

During the call, a person who identified himself as Cal told the operator that he found a teenager apparently passed out :

"We got a guy who's passed out. He drank way too much. We found him this morning."

Later, Cal admitted he wasn't present when the teen was drinking the night before but he came home, "... and a bunch of them were all drinking."

During the call, Cal can be heard asking an unidentified person in the frat house what happened:

"(Expletive deleted), man. What the (expletive deleted) did you guys do last night?"

The pledge, identified as Lynn Gordon Bailey Jr., of Dallas, was dead when authorities arrived at the house at 1080 14th St., on Boulder's "hill," across from the university.

Bailey was found a few hours after he had called his mother to tell her he had been accepted by Chi Psi and had earned a spot on a club lacrosse team.

"He had it all, he was absolutely at the top," his aunt, Lyn Feldman, said from Dallas. "He was thrilled about making the lacrosse team, and he was so excited about joining the fraternity."

She said Bailey considered himself an athlete and did not have a drinking problem, although he may have been celebrating Thursday night.

Feldman released a statement from the family, which said, "We are heartbroken over the tragic loss of our son, L. Gordon Bailey Jr. Gordie's life may have been short-lived, but he lived it fully with humor, affection, optimism, integrity and honor. Our tragedy is widely shared by all of those who had the privilege of knowing him."

The Boulder County coroner is waiting for toxicology tests to determine the exact cause of death for Bailey.

CU is reviewing its campaign to reduce student drinking but warned it cannot solve problems that may begin years before students enroll. However, officials said fighting alcohol abuse would take changes in society as a whole.

"It's very hard to talk about changing a population that we inherit after they've had 18 or more years of life experience," said Bob Maust, chairman of CU's Standing Committee on Substance Abuse. "They've been very well conditioned before we see them and nothing has changed in the larger society."

Maust said that Boulder, a town of about 100,000, has 60 bars within a mile of campus and more than 200 liquor stores. Every night, at least one bar offers women reduced drink prices, he said.

"It's a broad societal issue that would need community support, would need parental support, would need support from high schools, and now even middle schools," said CU spokeswoman Pauline Hale. "It's not an easy thing. I don't think universities can go it alone."

Bailey's death came less than two weeks after the death of Samantha Spady of Beatrice, Neb., a 19-year-old sophomore at Colorado State University in Fort Collins. She died of alcohol poisoning after consuming 30 to 40 beers and vodka drinks in 11 hours, authorities said. Her body also was found in a fraternity house.

Ironically, the 911 call for help for Bailey came the same morning that Fort Collins police released autopsy results on Spady, confirming she died from drinking too much.

The national Chi Psi organization has suspended the Boulder chapter's charter, banning its 76 members from participating in any fraternity events. The CU Interfraternity Council, which governs CU's fraternities, suspended recognition of the fraternity and halted social activities at all fraternity houses for an indefinite period.

In Boulder, the 2004 CU freshman class is the first under newly tightened alcohol policies that require notification of parents for a first violation and a one-semester suspension for a second violation.

Freshmen were required to complete an Internet-based alcohol education program, and the university has expanded its alcohol-free recreational and housing opportunities. CU also regularly runs newspaper advertisements and displays posters around campus in an effort to increase awareness and support for reducing student alcohol use, Maust said.

The success of such programs has been spotty over the years, both at CU and nationally.

In surveys of students at dozens of universities, the Harvard School of Public Health found that binge drinking rates have not changed significantly since 1993. At CU, about 58 percent of students in three surveys from 1993 to 2002 reported binge drinking at least once every two weeks. Nationally, about 44 percent of students report binge drinking, defined as a man having five drinks or a woman having four in a single sitting.

For six years ending in 2002, CU was one of 10 universities participating in a national research program funded by the Robert Wood Johnson Foundation to measure the success of efforts to reduce high-risk alcohol use.

Researchers said they cannot discuss the results until the study is published next month.

But in a summary, the foundation said the study found reductions of 5 percent to 11 percent in rates of binge drinking, frequent intoxication and taking up binge drinking in college, and in the rate of students reporting binge drinking at schools that adopted more of the recommended policies and programs. Those schools were not identified.

The study also found an 18 percent reduction in alcohol-related problems such as missing class, injuries or violations of the law.
