TALLAHASSEE, Fla. – Alcohol may have been a contributing factor in the death of a Florida State University student from Pompano Beach who died after an off-campus fraternity party, police said.

Andrew Coffey was found dead Friday morning after an off-campus fraternity party Thursday night in Tallahassee.

Although there are indicators that alcohol may have been a factor in Coffey's death, investigators are awaiting the results of an autopsy, Tallahassee police Chief Michael DeLeo said Monday.

DeLeo said investigators have interviewed more than 15 people, and additional interviews are planned.

Police arrived at the home on Buena Vista Drive shortly after 10:30 a.m. Friday and found Coffey unresponsive.

Coffey was a pledge of the FSU Pi Kappa Phi chapter and a graduate of Pompano Beach Senior High School.

FSU President John Thrasher announced Monday that all fraternities and sororities on campus have been suspended indefinitely.

The suspension comes after Garrett Marcy, 20, was arrested on a charge of cocaine trafficking. Marcy is a member of the Phi Delta Theta fraternity.

"For this suspension to end, there will need to be a new normal for Greek life at the university," he said. "There must be a new culture, and our students must be full participants in creating it."

Thrasher also instituted a ban on alcohol at all recognized student organization events during the indefinite suspension.

Students living at fraternity or sorority houses will be allowed to remain, but failure to comply with the terms of the interim suspension could result in immediate disciplinary action.

Thrasher said the timetable for lifting the suspension is up to the students.

"They must work with us and demonstrate they fully understand the serious obligation they have to exercise responsible conduct," Thrasher said.
