Twelve students are facing criminal charges after a teenager given 18 drinks in just 82 minutes fell down two flights of stairs and died.
Timothy Piazza, 19, was at an initiation party for the Beta Theta Pi fraternity house at Pennsylvania State University when he died on February 4.
Five members of the fraternity were already facing charges but many of those involved had said they had no idea how he had come to fall down two flights of stairs.
But now police and prosecutors have recovered a bombshell surveillance video that was deleted by one of the suspects Braxton Becker.
The video captured booze-filled games involving the students rapidly downing wine, beer and vodka in the fraternity house’s basement.
Eighteen members of the fraternity have been charged over Timothy Piazza’s death
Mr Piazza was given at least 18 drinks over a period of 1 hour and 22 minutes, said district attorney Stacy Parks Miller.
“He never once obtained those drinks for himself, brothers came up and gave them to him,” she said at a news conference.
A total of 17 fraternity members are now facing various charges, including involuntary manslaughter, aggravated assault, hazing and furnishing alcoholic beverages to a minor under the age of 21.
Timothy Piazza hit his head several times after falling down stairs.
Two of the people charged on Monday had previously faced criminal complaints that had been dismissed.
Mr Piazza, a student from Lebanon, New Jersey, seriously injured himself after becoming intoxicated at the party, taking two tumbles down flights of stairs.
His father James Piazza said: “[Tim] was a happy and caring human being and loving son who just wanted to join an organisation to find friendships and camaraderie.
“Instead, he was killed.”
