Members of a Penn State fraternity facing charges related to the death earlier this year of a pledge after a night of heavy drinking are due in court Monday for a hearing about whether there's enough evidence to head to trial.

Prosecutors in the case against the now-shuttered Beta Theta Pi chapter and 18 of its members are leaning heavily on video surveillance recordings made the night 19-year-old sophomore engineering student Tim Piazza was injured in a series of falls at the fraternity after a pledge acceptance ceremony that included heavy drinking.

The defendants face a variety of charges, with eight accused of dozens of crimes, including involuntary manslaughter and felony aggravated assault, while five others are accused only of a single count of evidence tampering.

Centre County District Attorney Stacy Parks Miller says prosecutors will play video in court, and she expects the hearing to last all or most of the day.

Authorities have said members of the fraternity resisted summoning help until well into the next morning.

A grand jury report described how members of the fraternity carried Piazza's limp body upstairs, poured liquid on him and even slapped him on the face. When one of them argued to call for medical help, he was confronted and shoved into a wall, the grand jury said.

Piazza, of Lebanon, New Jersey, died at a hospital Feb. 4 from traumatic brain injury and had suffered severe abdominal bleeding. His blood-alcohol measured at a dangerous level.

"I believe this is a case where the defendants have been overcharged by the district attorney's office," said defense attorney Michael Engle, whose client Gary DiBileo, 21, faces 56 counts, including involuntary manslaughter. "We hope to develop more information during the preliminary hearing process, and beyond, that will demonstrate that many of the charges in this case are just not applicable to the conduct."

Engle said DiBileo, a junior from Scranton who recently withdrew from Penn State, was said by a witness to have advocated for calling an ambulance at some point.
