DeKALB – Police dispute portions of a Fox TV news report into the Nov. 2 death of an NIU fraternity pledge but declined to discuss their investigation until it is finished.

Authorities are waiting on toxicology results and interviews before finalizing their investigation into the death of David Bogenberger, a 19-year-old freshman and 2012 Palatine High School graduate, Lt. Jason Leverton said. Pi Kappa Alpha has been placed on temporary sanctions, meaning members still live in the house at 1020 W. Hillcrest Drive in DeKalb but the fraternity cannot hold any events.

Authorities said early in their investigation that they suspected alcohol played a role in Bogenberger’s death because they found evidence of drinking near him. The fraternity, commonly known as Pikes, was hosting a “parents’ night” function the night before Bogenberger was found nonresponsive in a bunk-bed in the fraternity, Leverton said.
