A criminology graduate student charged in the November slayings of four University of Idaho students is no longer being

held in a Pennsylvania jail Wednesday morning after waiving his right to an extradition hearing the day prior.

Bryan Kohberger, a 28-year-old doctoral student and teaching assistant at Washington State University

waived his right to an extradition hearing in a Pennsylvania court on Tuesday, speeding up his transfer to Idaho to stand trial.

A jail official told ABC News about 9 a.m. EST Wednesday that Kohberger was no longer lodged at the Monroe County, Pennsylvania jail. He flew out Wednesday morning, the jail official said.

Students at the University of Idaho and nearby residents lived in fear for weeks as authorities seemed stumped by the mysterious and brutal stabbings

Nov. 13. Idaho police appeared to make a breakthrough, however, after searching for a white sedan seen around the time of the killings and analyzing DNA evidence at the crime scene.

nvestigators have said they are still looking for a murder weapon and a motive for the killings. 

More details about the case are expected to be released after Kohberger arrives in Idaho and an affidavit is unsealed.

But attorneys, law enforcement officers and others involved in the case won't be able to discuss the affidavit or other court documents after an Idaho magistrate 

judge on Tuesday evening issued a so-called gag order barring officials from talking publicly about many aspects of the case outside of court.
