BELLEFONTE -- Fraternity members returned to court Monday for part two of a hearing about their involvement in the death of a fellow Penn State student.
That hearing into the death of Timothy Piazza from New Jersey began last month.
Prosecutors spent much of the morning presenting text messages sent by Beta Theta Pi fraternity brothers after the death Piazza in February.
The Centre County D.A. is trying to make the case that the frat brothers knew they were negligent and tried to hide evidence.
The parents of Timothy Piazza were once again at the courthouse in Bellefonte to hear the evidence being presented against the Beta Theta Pi brothers.
Last month at the hearing, surveillance video was shown of their son visibly drunk and injured after falling twice down the basement stairs of the fraternity house.
PSU fraternity brothers haven't been speaking to the media in Bellefonte.
The Centre County district attorney hopes dozens of text messages including one that said, "Make sure the pledges keep quiet about last night," will speak for themselves.
Investigators believe Ed Gilmartin of Scranton sent that message the day after Piazza fell head first down a flight of stairs at the Beta Theta Pi fraternity house at Penn State back in February.
Gilmartin is one of two fraternity brothers who waived their preliminary hearing. 16 others including Gary DiBileo of Scranton were in court.
A judge will need to decide if there is enough evidence against these men to go to trial.
In court last month, surveillance video from the night Piazza fell showed pledges taking part in a speed drinking event called "the gauntlet" where they were forced to chug alcohol.
Investigators say DiBileo had been through the hazing ritual himself and the night Piazza fell, DiBileo helped coordinate the obstacle course.
Dibileo told investigators he was concerned about Piazza. In a text message after Piazza's fall, DiBileo wrote, "We tried our best to get him to the hospital, wish people listened."
When asked why he didn't call an ambulance, DiBileo told investigators, "We wanted to make a decision as a group."
"What we heard was somebody that was still saying they wish that their pleas to call 911 had gone answered. He was one of the individuals that wanted to help this kid," said DiBileo's attorney Michael Engle.
The men's charges range from involuntary manslaughter to tampering with evidence.
This hearing in Centre County court is to determine if prosecutors have enough evidence for this case to go to trial. It is expected to last through Tuesday.
