Bryan Kohberger, a painfully awkward, arrogant introvert and criminal justice student, believed he could have committed “the perfect murders,” James Patterson said.

“One of the things that professor [Dr. Katherine Ramsland] said that with murderers like this, they get tunnel vision – they panic, and they miss things,” the award-winning author told Fox News Digital. 

“So here was Kohberger who almost committed the perfect murders – except [he had] that tunnel vision,” Patterson shared. “He left that knife sheath behind. And that’s what ultimately led to his arrest.”

“It was a hard case to solve,” he reflected. “[Investigators] were very fortunate that Kohberger made that one really big blunder… He didn’t make a lot of mistakes. So it was a tough investigation… He might’ve never been caught. We might’ve been writing about God knows what right now.”
