The night Piazza fell, Rizzo told investigators, he heard the sound and went to the top of the basement stairs.
In a group text message, one of the fraternity members wrote: "Tim Piazza might actually be a problem".
Piazza consumed a fatal amount of alcohol and fell numerous times the night before he passed away. But when he arrived later, fraternity members told him to "catch up", according to the court documents.
At 3:30 a.m., Piazza staggered around the house, again falling and striking his head.
Piazza would eventually fall down the basement stairs once more, striking his head yet again.
"We have a friend who's, uh, unconscious. he's. hasn't moved. probably going to need an ambulance", the 911 caller said.

One brother told investigators Piazza "felt cold to the touch, his skin appeared pale, and his eyes remained half-open". Students stepped over him, according to the findings. Four fraternity brothers carried his limp body back upstairs, where some poured liquid on him, and another slapped him three times in the face, the grand jury said.

Piazza died while pledging to the fraternity in February.

As ABC News reported Friday, all defendants charged with involuntary manslaughter were preliminarily arraigned Friday afternoon.
On Wednesday, the university's president said they must work harder to prevent tragedies like that but many are questioning whether the university should be held accountable. They are prohibited from having alcohol and non-prescription drugs, can not leave their home state without express permission from the judge and must surrender their passports, the district attorney said.
A Pennsylvania judge is expected to arraign the defendants - including two from the Philadelphia region - and set bail. "I empathize with the family of the deceased, I empathize with the family of those who are charged". "Having said that, it is my position that there is no criminality on the part of my client". Instead of calling for help immediately, the frat members allowed him to "sleep it off", thinking he was simply passed out from drinking.
But as CNN's Sara Ganim reported, Beta Theta Pi International Fraternity had disciplined its Penn State chapter twice.
Beta Theta Pi International Fraternity said in a statement, "The nature of those charges are incredibly disheartening as the organization and its membership continue to grieve Tim's passing and the pain experienced by his family".
The chapter house was celebrating with Piazza, Davis and other students who had just accepted bids to join the fraternity.
