Reached at his home in Florida, Bogenberger's father said the family was still trying to absorb the news of his death.



"I talked to him the night before last, even saw his smiling face on a video chat, and that was the last time I saw him," Gary Bogenberger said. "He said he was getting straight As, one B in math, and doing very well."



Bogenberger, a triplet, graduated in June 2012 from Palatine High School with his brother and sister, then decided to attend NIU to study finance, his father said. He was pledging at the fraternity where he was found.



"None of us have really digested what is going on yet," he said.



The university has made counselors available for students who want to talk about Bogenberger's death.



"Our hearts are broken -- you never want to see this happen," university spokesman Brad Hoey said. "We are still trying to get to the bottom of what happened."



Hoey said that based on interviews with other students, it appeared that alcohol may have been a factor.



"We do believe that alcohol may have been involved," he said. "That is one of the things that was shared, that there was alcohol present."



Hoey said that the fraternity has a good reputation at the university.



"It's the Pike House, a very well-known fraternity," he said. "Not a lot of problems with partying. It's a fraternity in good standing at this time."
