Presumptive University of Idaho murder suspect Bryan Kohberger may have left a “business card” showing he was at the scene of the gruesome murders in Moscow, Idaho — and the brutality of the crime suggests he may have, according to experts has killed before.
In a “Dr. Phil” on Friday, experts speculated that Kohberger, 28, deliberately left an empty knife sheath in the room where college students Kaylee Goncalves and Madison Mogen were murdered on Nov. 13.
The lifelong best friends were stabbed to death early in the morning of November 13 along with their roommate Xana Kernodle and boyfriend Ethan Chapin.
Former FBI Special Agent Jonathan Gilliam said he believed investigators would find the knife because, much like Kohberger’s car, it was “part of his operational tools,” Fox News reported.
Trial Attorney Mercedes Colwin agreed that they would eventually find the knife and then suggested that the scabbard might have been left at the scene on purpose.
“It could be, I mean, it’s almost like — and we’ve seen that with other killers, it’s their business card, ‘I got that,'” she said during the special.
“Especially when you think you’re smarter than everyone else, and he certainly – he had gloves, at least that’s what’s assumed he had gloves. He tried to cover himself, did something to dispose of the clothes, if he is indeed the killer then of course that’s something that could just be a business card and have left there.”
The panel of experts convened on the show discussed the possibility that this wasn’t Kohberger’s first murder, potentially making the criminal justice doctorate a serial killer.
Gilliam said he felt the murder suspect may have killed before, and in a similar way.



“I think he’s most likely been killed before,” Gilliam said. “Not four people, but I think he’s probably stalked and possibly killed women before.”
Colwin added, “If he’s the killer, this viciousness, brutality and slaughter of these four people, I can’t imagine this is the first time he’s actually the killer.”
Forensic scientist Joseph Scott added that while he thought it might be Kohberger’s first murder, he believes it certainly wasn’t the first time Kohberger had tried to get away with something wrong.

When asked if it was Kohberger’s first murder, he replied: “Murder? Possibly. bad deed? No.”
Kohberger, a graduate student studying criminal justice at Washington State University — about 10 miles from the University of Idaho — has been charged with four counts of first-degree murder and one count of burglary in the grisly quadruple murder.
His December 30 arrest came after a seven-week nationwide manhunt that had gripped America. A motive for the deeds or a connection between Kohberger and the victims could not be determined so far.
A preliminary status hearing for Kohberger was set for June 26.
