BELLEFONTE, Pa. (AP) – The father of a Penn State student who died of injuries suffered during a fraternity pledge night is expressing exasperation over the pace of a pre-trial hearing for students charged in connection with his son’s death.

Jim Piazza says in a statement released Tuesday he hasn’t seen much evidence of remorse from defendants in the courtroom. He’s urging the defendants’ parents to pressure their sons to “come forward with everything they have that is helpful.”
