New evidence revealed this week brought new charges in the hazing death of Penn State University student Timothy Piazza. Authorities recovered video footage that had allegedly been deleted by Piazza’s peers, showing he consumed 18 alcoholic drinks in one hour and 22 minutes, according to the Centre Daily Times.

Piazza, 19, died in February after a hazing ritual at the Beta Theta Pi fraternity known as “the gauntlet.” Initial surveillance video showed that Piazza, severely intoxicated, had fallen down the stairs of the house more than once. The video also revealed that fraternity brothers did not call for help for more than 12 hours, opting instead to slap him and pour liquid on him.

The new video evidence was recovered by the FBI from security camera video which was previously deleted from the fraternity house, District Attorney Stacy Parks Miller confirmed Monday. The footage was deleted by a former member of Beta Theta Pi two days after Piazza’s death, according to detective David Scicchitano.

“The basement video captures the ongoing hazing that occurred on bid acceptance night and the continued repeated furnishing of alcohol by Beta brothers to Tim Piazza, as well as the other pledges, throughout the evening,” the district attorney’s office said in a statement, according to WTAE-TV. “The video was deleted after brothers were made aware that an investigation into Tim Piazza’s death was underway and police planned to obtain the footage."

The footage in question led to new charges against 12 people in the case, ranging from felony aggravated assault to misdemeanors. With the addition of those charges, 17 people have now been charged in connection to the case.

“Brothers were coming up to him and giving him those drinks,” Miller said. “That’s the evidence that the commonwealth now has.”

Reports from after Piazza’s death showed other instances of fraternity members attempting to cover up the situation. At least one text was exchanged about “getting rid of any evidence of alcohol” and ensuring that pledges “keep quiet about last night.” Texts also showed they discussed the video footage filmed inside the house.

“The videotape is horrible and it is gruesome,” Tom Kline, an attorney for the Piazza family, told CBS News in June of the initial footage. “No parent wants to see what is apparently on this videotape.
