'They Killed Him': Family Of NJ Man Who Died At Frat Party Speaking Out

The New Jersey family of a Penn State student who died after falling during a fraternity party in February is speaking out, making several appearances during Monday morning news programs. In an interview with NBC "Today's" Matt Lauer, Timothy Piazza's father, Jim, said the fraternity brothers who failed to call for help, allowing his son to suffer for 12 hours, are responsible for his death.

"They killed him," Jim Piazza said. He appeared on the program alongside his wife, Evelyn, and son, Michael, also a Penn State student. The interview was taped on Mother's Day, according to Lauer. The family, of Readington Township, New Jersey, also appeared on "Good Morning America" and CBS Monday morning.

In the "Today" interview, the family detailed a heartbreaking timeline of how they learned Tim was injured and would not survive after authorities say he drank dangerous amounts of alcohol on Feb. 2 and fell 15 feet down a flight of stairs. No one from the fraternity house called 911 until the following morning.

Eight fraternity brothers are facing manslaughter charges in connection with his death. Ten others face related charges of reckless endangerment, tampering with evidence and providing alcohol to minors, among others.

During the "Today" interview, the family said they have not yet viewed the surveillance footage from that night. Tim's parents said they would only watch it alongside the Penn State board of trustees or President Eric Barron if it means a positive change would result.

Michael, Tim's brother, said he was the first one in the family to learn something was wrong. One of Tim's roommates called him to see if he knew where he was because he hadn't come home from the night before. Michael called the local hospital and learned his brother was in the emergency room.

"When I got there, I found out pretty quickly how serious it was," his brother said. He was the one who broke the news to his mother that Tim was gravely injured.

When his parents arrived, they were informed by the doctor that Tim had an non-recoverable brain injury. His parents went in, talked to him and held his hand, his father recalled. "A tear came to his eye," his father said. That prompted him to ask the doctor if Tim could hear them. "Maybe," the doctor told him.

"Frankly I don’t want to know if he heard us or not because if he heard us, he knew he was going to die," Jim told Lauer.

Jim said he also asked the doctor if the amount of time that Tim was left to suffer with his injury played a role in the fatal outcome. The doctor told him, that yes, if he was brought in earlier he could have survived, Jim said.

"They killed him," Tim's father told Lauer.

He also noted not one person from the fraternity or Penn State attended Tim's wake or funeral.

The family announced a foundation has been created in Tim's name. You can learn more about it here.
