STATE COLLEGE, Penn. -- It took members of a Penn State fraternity 12 hours to call for an ambulance after Timothy Piazza fell down the basement stairs, according to police.

Lt. Keith Robb of State College Police said at a press conference that the 19-year-old Hunterdon County resident fell down the stairs during a party at the Beta Theta Pi fraternity house, on the Penn State campus, on Thursday night around 11 p.m., but no one called for an ambulance until almost 11 a.m. on Friday.

Piazza was unresponsive and unconscious when police arrived and took him to Mount Nittany Medical Center in State College. He was then flown to Hershey Medical Center, where he was pronounced dead on Saturday.

Robb said an investigation was ongoing, and did not offer an explanation as to the delay in dialing 911. An autopsy is scheduled for Tuesday. Robb said the fraternity is cooperating with the investigation and has provided surveillance video.

Piazza, an engineering major, graduated from Hunterdon Central Regional High School in 2015.

Penn State spokeswoman Lisa Powers said that the fraternity has been suspended and cannot participate in any fraternity or sorority activities. It will not be recognized as a student organization for the duration of the investigation.

Tim's brother Mike posted on his Facebook page that he is "utterly devastated" by Tim's death and that he lost his "other half." Mike Piazza, who is also a student at Penn State, wrote, "My brother was my best friend. If I ever needed to talk or just wanted someone to joke around with, he was there. When the world was too much, I had one person who I could turn to for anything. He was the most vibrant person I knew, and his sole mission in life was to make other people smile."

According to Mike's Facebook page, his brother's funeral is Saturday at 9:30 a.m. at Our Lady of Lourdes Church in Whitehouse Station. His wake is scheduled for Friday at the church from 4 p.m. to 8 p.m.
