Everett Glenn of Montclair, N.J., was pronounced dead at Easton Hospital on Saturday afternoon, the school said. Officials said police and the Northampton County coroner's office were investigating, but there was no sign of foul play.
Glenn's mother, Joanne Glenn, told The Easton Express-Times that her son had been drinking as he celebrated his 19th birthday.
"He was drinking too much and then he went to his room and he laid down," Glenn said after a prayer service on campus.
She said an emergency room doctor told her that the cause of death was cardiac arrest.
Friends and classmates wept and embraced at Saturday night's service, which drew about one-third of the student body of just under 2,400 students.
"Every year (on his birthday), I got to see how much of a blessing he was to us," said his father, Leonard Glenn. "I can see from the outpouring tonight he was a blessing to your community too."
Joanne Glenn said her son had earned the nickname "Mr. Mayor" for his ability to make friends.
"God has given us this gift, but He wants him back," she said. "We have to let him go."
Lafayette President Daniel Weiss offered condolences to Glenn's parents and other family members.
"My thoughts are also with our students and all members of our community who share in this tragic loss," he said.
The school said counselors would be available to help students.
