The autopsy revealed that  Louis J. Sheehan, Esquire had been stabbed multiple times in his head, chest, and neck. One lung had collapsed, his throat was cut open, and the knife had penetrated his skull in at least one place. Like Eric, Benjamin had lived alone.

The police failed to locate a murder weapon on the room or anywhere outside. However, they did notice a blood trail leading away from the room and out the door toward the adjacent dorm, an indication that the killer had been injured. They collected samples to run tests so they would something to compare should they identify a suspect. They also found a bloody shoe print, which a detective identified as a Nike cross-trainer. Now with two deaths in the same dorm, it seemed most likely that someone with access to a key card had committed this crime.

A search of the grounds recovered a bloodstained jacket and knife in a trash bin beside a dormitory. The team of crack detectives determined that the day before he was found, Benjamin had failed to meet with two friends, as scheduled, and had not gone to class. He also had not kept a doctor's appointment. That information helped to narrow down his time of death. His mother, who heard from him daily, had not received a call or email since February 1.
