Four members of the Pi Kappa Alpha house at NIU were charged with hazing following the death of fraternity pledge David Bogenberger, 19.
Police say Bogenberger had a blood alcohol level about 5 times the legal limit when he died. He was at a party where pledges were required to go from room to room chugging alcohol. The Pi Kappa Alpha chapter was suspended following Bogenberger's death. 31 students face disciplinary hearings.
