The doctoral student accused in the November stabbing deaths of four University of Idaho students will be transferred to Idaho to face murder charges there, after he agreed at a court hearing in Pennsylvania not to fight extradition.
Bryan Kohberger, 28, was taken into custody last Thursday in Monroe County in eastern Pennsylvania, where he was visiting family.
Mr Kohberger has been working toward a criminal justice PhD degree at Washington State University, located near the University of Idaho campus.
Jason LaBar, his public defender in Monroe County, told NBC's "Today" show that Mr Kohberger believes he will be exonerated. He faces four counts of first-degree murder and felony burglary.
The crime stunned the small college town of Moscow in northwestern Idaho, where the four victims - three women and one man - were found dead on the morning of 13 November in the women's house.
The victims - Ethan Chapin, 20, of Conway, Washington; Xana Kernodle, 20, of Avondale, Arizona; Madison Mogen, 21, of Coeurd' Alene, Idaho; and Kaylee Goncalves, 21, of Rathdrum, Idaho - all suffered multiple stab wounds, according to authorities.
Mr Chapin was Ms Kernodle's boyfriend.
Two other female roommates in the house at the time of the killings were unharmed, apparently having slept through the attack.
Ms Kernodle and Mr Chapin had attended a party the night before, while best friends Ms Mogen and Ms Goncalves had visited a local bar and food truck, with all four returning to the house before 2am.
Authorities have said the murders occurred between 3am and 4am.
Authorities have not publicly disclosed a motive but have said they are confident Mr Kohberger is responsible for all four killings.
A probable cause affidavit that lays out the basis for the charges will offer additional details, prosecutors have said, but it remains under seal until Mr Kohberger is physically in Idaho.
