Kohberger is the prime suspect in stabbings that shocked 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 Nov. 13.

Kohberger faces four counts of first-degree murder and felony burglary, and a court order says his transfer to Idaho must occur within 10 days.

Authorities in Pennsylvania and Idaho are discussing his transport, Pennsylvania State Police Major Christopher Paris said at a news conference, but the timing remained unclear.
