BELLEFONTE, Pa. - The father of the New Jersey teen who died after a hazing at a Penn State fraternity said he was highly offended to see defendants and their families act like they were at a fraternity get-together following Monday's preliminary hearing.

"Following the hearing, most, but not all, of the fraternity brothers and their families got together, laughed, patted each other on the back and hugged as if this was just another fraternity get-together," James Piazza, father of Timothy Piazza, said on Tuesday. "We are highly offended by the insensitivity displayed given the severity of the crimes committed and ultimate outcome."

It was a long and emotional day as the hearing was held for 16 of 18 Penn State fraternity brothers accused in the hazing death of Timothy, 19, of Readington Township. Three hours of video taken from surveillance footage inside the Beta Theta Pi fraternity house was also shown publicly for the first time during the hearing.

Magisterial District Judge Allen Sinclair, after almost 10 hours on Monday, ordered a continuance to be held later this summer to allow defense attorneys a chance to cross-examine State College Police Det. David Scicchitano, the only person who testified.

At times exchanges between defense attorneys and Centre County District Attorney Stacy Parks Miller became heated, according to PennLive, a sister site to NJ.com.

Speaking after the hearing, Parks Miller said the decorum shown in the courtroom shocked her. She also spoke about the defendants joking and laughing after the hearing. "I don't see anyone acting sad," Parks Miller said of the defendants who appeared in court.

"This is about Tim Piazza," she said, referencing what she called "games" and "grandstanding" by some of the defense attorneys. "This is about a dead boy."

One defense attorney, Andy Shubin, stood up after a break and said it was "cruel and inhumane punishment" to make the attorneys be in court for over 10 hours, James said, adding other defense attorneys supported his statement, even making jokes.

"Of course, this comes right after all of them watching video for five hours of what real cruel and inhumane punishment was when the fraternity brothers essentially murdered our son, tortured him, held him captive and left him for dead over a 12-hour period of time," James said. "Thankfully, the judge quickly brought them in order."

Some of those representing the fraternity members suggested their clients should not be held individually responsible for Timothy's death. Michael Engle, who represents Gary Dibileo, said he did not hear anything presented Monday that linked his client to Timothy's death.

"I was underwhelmed by evidence that was presented," Engle said.

James Piazza and Evelyn Piazza, who were in the courtroom in the morning, left when prosecutors said they would be showing three hours of surveillance footage from inside the fraternity house on the night Timothy fell and into the next morning, when, almost 12 hours later, a fraternity member finally called 9-1-1.

"This was a very difficult day, to state the obvious, for the Piazza family," their family attorney, Tom Kline of Philadelphia, said. Kline said they could not watch the surveillance video, saying it was "just too painful and too difficult" for them to see. "They certainly heard shocking, disturbing testimony," he added.

Kline said the Piazza's will be at the next hearing.

"They believe that there should be punishment for those who committed these crimes," Kline said, according to PennLive. "And they believe, more importantly, that this will lead to deterrence."

On the night of Feb. 2, Timothy was one of 14 pledges at a bid acceptance party that including a hazing ritual known as "the gauntlet," involving running between stations where beer, wine and vodka were drunk in quick succession.

Visibly intoxicated, Timothy fell face-first down a set of basement stairs, according to a grand jury report. He was brought back upstairs by fraternity members, but it was almost 12 hours before anyone called 9-1-1. Portions of the surveillance video shown Monday are of the hours he spent on a couch, and then alone, in the fraternity's great hall, appearing to be in agony for much of the time.

The footage showed members sitting on his legs trying to keep him from moving, and throwing shoes and liquids on him in an apparent attempt to revive him. Later, while alone, Timothy is seen struggling, sometimes in a fetal position, other times striking his head in repeated falls, before he is later found in the basement a second time.

An investigation, according to the grand jury report, also revealed members discussed what to do and discussed ways to cover up what happened before calling 9-1-1 on the morning of Feb 3.

While a grand jury concluded there was enough evidence to charge 18 members of the fraternity, and the fraternity itself, with crimes ranging from involuntary manslaughter to aggravated assault and lesser offenses, Pennsylvania law requires a preliminary hearing to again show there is cause for the charges, Parks Miller said.

Only two people, Ed Gilmartin, vice president of Beta Theta Pi, and Ryan Foster, waved their right to a preliminary hearing. Both face a single count of tampering with evidence.

Parks Miller said by showing the video - combined with testimony from Scicchitano - the state seeks to show fraternity members had prior knowledge of the dangers involved in an alcohol-fueled hazing and recklessness by doing it again. She pointed out the fraternity had pledges run "the gauntlet" before, resulting in heavily-intoxicated students and injuries from falls.

"We charged these people for deliberately getting these young men to a fatally high level of alcohol," Parks Miller said. "And as a result, they are the cause of Tim coming almost to a .4 (blood-alcohol content) level of alcohol."

His injuries suffered in the fall, Parks Miller said, starting a chain of events that led to his death.

"When he falls, gets injured, spleen, head, repeatedly, then he can't protect himself from the alcohol and the injuries and it goes on and on and on 'till he dies," she said.

Fraternity members didn't help Timothy or render aid, she said, and, "At that point they caused him to be in that condition."

Julian Allatt, representing Lars Kenyon, said during the hearing that for 10 minutes after police responded to the 9-1-1 call, no first-responder rendered first aid either, according to PennLive.

Others suggested voluntary drinking by Piazza contributed to his blood-alcohol content reaching between .28 and .36 percent by the time he fell the first time, PennLive reported.

The fraternity, suspended in 2009 for alcohol-related violations, had reopened as a "dry" house in 2010, with the cameras installed as a condition of the resumption of its charter.

The fraternity was permanently shut down by Penn State, and it was suspended by the Beta Theta Pi International Fraternity. Penn State's trustees also voted on sweeping changes to be made to its Greek system.
