BOULDER, Colo. -- University of Colorado football fans observed a moment of silence for an 18-year-old freshman found dead at a fraternity house as ramifications from his death mounted.

Lynn Gordon Bailey Jr., of Dallas, was found in a common room at the Chi Psi house after police received a 911 call early Friday. Bailey, a business major and a pledge at the fraternity, had smudged ink stains on his face, but Boulder police spokeswoman Julie Brooks said investigators did not know where they came from.

A cause of death has not been released. The Rocky Mountain News reported that grief counselors told students the death was alcohol related, which Brooks would not confirm.

The Interfraternity Council, which governs CU's fraternities, announced it had suspended recognition of Chi Psi pending an investigation while CU-Boulder Chancellor Richard L. Byyny met with Bailey's family on campus.

In a statement, Byyny said the university would begin reviewing its relationship with the Greek system.

Chi Psi already had its national charter suspended after Bailey's death, banning its 76 members from participating in any fraternity events, said Sam Bessey, the executive director of the national Chi Psi organization.

The Interfraternity Council also suspended social activities at all Greek houses for an indefinite period.

"Words cannot express how deeply this tragedy has impacted the Greek community," council President Nick Baker said.

University officials met with Bessey, who flew in to Boulder Friday from the group's headquarters in Tennessee.

During the meeting, they discussed housing options for the roughly 36 members living in the house, Bessey said. The university offered dorm rooms, while many were staying with friends. The students could remain in the house, though, and men entered and left there often on Saturday.

"There will not be any hanging out in the sense of a party or gathering," Bessey said.

Bessey also met with the fraternity and urged them to speak with counselors.

"I've had productive meetings with the undergraduates. They are scared and they're sad," he said. "Gordon's death will be a life-altering occurrence for each of the young men in Chi Psi and its extended family."

Pending its own investigation, the national Chi Psi group could revoke the CU fraternity's charter, ending their existence at the school at least for a while.

Bailey was the second student found dead in a Colorado fraternity this month. Samantha Spady, a 19-year-old sophomore at Colorado State University in Fort Collins, died of alcohol poisoning at the Sigma Pi fraternity on Sept 5. She died with a blood alcohol level of .436 -- five times the legal limit for driving. An autopsy determined that she had 30-40 drinks in an 11-hour period.

The moment of silence before CU's game against North Texas also was in memory of Spady. A candelight vigil on campus for Bailey was planned for Monday.

At Deerfield Academy in Massachusetts, where Bailey went to school prior to CU, he was being remembered as a great friend and a great student.

"Gordie Bailey was involved in every aspect of school," said Lee Wicks, secretary at the prep school. He was involved in football in the fall, theater and dance in the winter, and lacrosse in the spring, Wicks said.

The school was going to organize a memorial in his honor to remember his life, but the date had not yet been set.

Bailey had just written to his friends saying that he loved living in Colorado because of the outdoors. He said he was happy at school and described how he had just earned a spot on the lacrosse team -- quite an accomplishment for an incoming freshman.

CU has been trying to overcome a reputation hurt by recent events tied to alcohol. It has been dubbed the nation's top party school by the Princeton Review and its football program recently was criticized for the use of sex, drugs and alcohol by player-hosts during recruiting visits.

Since then, the university has toughened its alcohol violation policy. Instead of possible suspension after three violations, students now can be suspended after two and parents are notified after the first offense. Freshman also had to take a mandatory online alcohol education course before the fall semester began.

Bessey said Chi Psi chapter officers discuss alcohol use during a yearly leadership institute. Every chapter also goes through a risk management program, which includes a portion on alcohol.

He said alcohol abuse is a problem for every college campus and fraternity.

"It's an issue for us as much as any university," Bessey said.
