Here's Why The Idaho Murders Suspect Agreed To Be Extradited, According To DA

A Pennsylvania district attorney official suggested that Bryan Kohberger, the suspect in the killing of four Idaho university students, waived his extradition rights to know the content of the affidavits of probable cause.

Mike Mancuso, the first assistant district attorney of Monroe County, said he believed that Kohberger wanted to return to Idaho to know what was inside the documents, calling it a "significant development."

"Having read those documents and the sealed affidavits of probable cause, I definitely believe that one of the main reasons the defendant chose to waive extradition and hurry his return back to Idaho was the need to know what was in those documents. So, that's a significant development," Mancuso said, Fox News reported.

During his court hearing on Tuesday afternoon, Kohberger signed the extradition document and waived his right to challenge his arrest in connection to the four counts of first-degree murder the authorities were charging him.

The suspect was asked by Judge Margherita Worthington if he had any mental issues that could affect his decision to waive his extradition. Kohberger said "no" to the judge, CNN reported.

Judge Worthington declared that the suspect's custody must be handed over to Idaho's Latah County District Attorney's Office within ten days.

CBS News learned that Idaho authorities could expedite Kohberger's extradition within 72 hours after the hearing.

But Major Christopher Paris, a commander of the Pennsylvania State Police, is worried about Kohberger's extradition to Idaho, noting that there are "security concerns." But he did not provide any logistical plans regarding the suspect's turnover.

The Monroe County Correctional Facility warden described Kohberger as a "model prisoner" and did not cause any problems during his time in detention while awaiting his extradition trial, a source familiar with the suspect's status told CNN.

Extradition lawyer Jason LaBar echoed the warden's remark, saying that Kohberger was "in a calm demeanor" and understood the case proceedings.

Kohberger's family was also present during the court hearing since they were accompanied by a representative from the public defender's office.

The suspect's mother collapsed when the judge told Kohberger he would be sent back to Idaho to face murder charges.

Kohberger's family had earlier released a statement that they would "let the legal process unfold," adding they still believe in the suspect's innocence.

Kohberger, a Ph.D. student at Washington State University, was arrested in his family's home in Pennsylvania last Friday after he was accused of killing four University of Idaho students — Kaylee Goncalves, 21, Madison Mogen, 21, Xana Kernodle, 20, and Ethan Chapin, 20 — in November.
