Bellefonte - The lawyer for a Penn State fraternity president accused in the death of a pledge after a night of drinking and hazing argued Wednesday that his client didn't see anything to make him think the pledge was at risk of dying.Defence attorney Frank Fina said during a preliminary hearing that there was no evidence that former Beta Theta Pi president Brendan Young acted maliciously the night 19-year-old Tim Piazza, of Lebanon, New Jersey, was fatally injured."He wasn't there through the whole night. He did not observe any injuries to Mr Piazza. He did not observe anything that would lead him to believe that he was at substantial risk," Fina told a district judge who will have to decide whether to send the case against Young and 15 others to trial.Fina said Young's entire exposure to Piazza's drinking lasted only 12 seconds, and there are unanswered questions about how much Piazza drank and how he obtained it."We can't say at what point his tragic injuries were fatal that night," Fina argued. "And we can't identify all of the intervening events and the unknowns that contributed or even caused some of Mr Piazza's injuries."In chargeCentre County District Attorney Stacy Parks Miller said Young was "in charge of the fraternity" and sent texts afterward indicating he was responsible.She said the defendants led Piazza to hazing and excessive speed drinking, aiming to see "how drunk they could get him in the shortest period possible".That behaviour, she argued, meets state standards for criminal liability."They knew that death was a potentially serious consequence," Parks Miller said. "They proceeded in the face of it anyhow. That is recklessness."Authorities have said Piazza ingested a dangerous amount of alcohol and fell several times during the night of a membership bid acceptance ceremony in February.Security cameras showed Piazza spent an excruciating night in the fraternity as members made halfhearted and even counter-productive efforts to help him.Piazza was unconscious by the time he was discovered in the Beta Theta Pi basement the next morning, and he was found to have suffered severe head and abdominal injuries.Two other defendants have waived their preliminary hearing.
