Former FBI agent Jennifer Coffindaffer mentioned in a Newsweek article that it would be rare for a first-time offender to commit a quadruple homicide; therefore, it’s not outside the realm of reason that this may not have been the first time Kohberger has killed someone. Rahmani, speaking exclusively to Grunge, agrees. He said it appeared that Kohberger knew more than most killers, possibly because of his studies of criminal justice.

“Most murderers don’t have the wherewithal or knowledge to turn off their phones, for instance,” Rahmani said. Whereas cell data shows Kohberger’s phone was near the site of the murders (pictured) later that morning, it was untraceable during the time the murders took place (via Fox News). Rahmani added, “And here is someone who killed four people without a very clear motive, and he did it in a matter of nine minutes, reportedly, so he may very well have killed before. This guy was just so effective, so careful and so sophisticated in his killings so if he killed before, you would think he would have been similarly careful.”
