A prison guard at the Pennsylvania jail where Bryan Kohberger was taken in the immediate aftermath of his arrest has now been called as a surprise witness in his capital murder trial.

In new court documents filed in Pennsylvania this week, two more individuals - William Searfoss and Anthony Somma - were hit with summons to testify in the upcoming trial.

Searfoss works as a correction officer at Monroe County Correctional Facility, where Kohberger was held following his arrest at his parents' home in Albrightsville, back on December 30, 2022.

The criminology PhD student was housed at the jail for five days before he was extradited to Idaho on January 4, 2023, to face charges for the murders of Kaylee Goncalves, Madison Mogen, Xana Kernodle and Ethan Chapin.

It is not clear if Searfoss had interactions with Kohberger during his time behind bars at the jail.
