Idaho murder suspect's parents subpoenaed for Pennsylvania grand jury testimony.

The parents of Bryan Kohberger, who is accused of killing four University of Idaho students, have been subpoenaed to testify before a Pennsylvania grand jury. Kohberger's father is expected to testify in a sealed proceeding, while his mother has already testified. The testimony may be shared with prosecutors in Idaho. It is unclear what potential crime the grand jury is investigating. Kohberger was arrested at his parents' Pennsylvania home and extradited to Idaho to face murder charges.
