Former assistant FBI director says he believes Idaho killer suspect has killed before

Former assistant FBI Director Chris Swecker said Tuesday the man charged with murdering four Idaho college students has probably killed before.

"I hate to say this because it sounds so grim, but I don't think this is the first time he's ever killed," Swecker said about accused killer Bryan Kohberger on the John Solomon Reports podcast. "I think the FBI is probably scouring the area around Pennsylvania where he spent a lot of time."

The 28-year-old Kohberger was arrested at his parents’ house in eastern Pennsylvania and charged with first-degree murder in connection with the Nov. 13 deaths of four University of Idaho students: Kaylee Goncalves, Maddie Mogen, Xana Kernodle and Ethan Chapin. 

He was at the time of the killings pursing a doctorate degree in criminology and forensics at Washington State University. 

Kohberger's family released a statement this weekend asking for the legal process to play out. 

"We have fully cooperated with law enforcement agencies in an attempt to seek the truth and promote his presumption of innocence rather than judge unknown facts and make erroneous assumptions," the statement read. 

"First and foremost we care deeply for the four families who have lost their precious children. There are no words that can adequately express the sadness we feel, and we pray each day for them," it continued. 

The family asked for their privacy to be respected as they "let the legal process unfold and as a family we will love and support our son and brother."

Law enforcement reportedly tracked Kohberger closely as he drove cross-country from Washington, just miles for the Idaho campus, to his parents’ home in Pennsylvania.

Swecker compared the alleged murder suspect to Ted Bundy. 

"Most of the the behavioral scientists will tell you that there's an urge that develops when it comes to killers - like Ted Bundy," Swecker said. "He's "a perfect specimen to study here in comparison to that case. I think they're very similar."

Swecker noted that Bundy would kill, then move, which he speculates is what Bryan Kohberger is doing. 

"He killed and then he relocated-probably about two or three times," he said.
