A Pennsylvania court has released records in the Idaho student killings case, showing that police recovered a knife during a search on the perpetrator's parents' house in Pennsylvania.

On December 30, the FBI and Pennsylvania State Police conducted a nocturnal tactical operation and captured suspect Bryan Kohberger at his parents' home in the Pocono Mountains, according to Fox News.

They looked into his house, vehicle, garage, and shed on the premises to find evidence in connection to the Idaho murders case.

The fresh warrants show cops removed a door panel from his vehicle, seat cushions, headrests, seatbelt, visor, brake and gas pedals, a band-aid, "maps and documents," and other things.

Police seized a knife and a Glock pistol with three empty magazines from the residence. They confiscated a mobile phone, a computer, a black hat, and face masks, per USA Today.

A phone bill, a handwritten password, a book with highlighting "on page 118," and a "green leafy substance" in a sealed container were also on the list.

Brutal Killings

Bryan Kohberger arrest occurred more than three months after the Idaho murders in Moscow, Idaho on November 13 that claimed the lives of students Ethan Chapin, 20, Madison Mogen, 21, Kaylee Goncalves, 21, and Xana Kernodle, 20.

Bryan Kohberger, a former doctorate student at Washington State University in Pullman, was charged with four counts of first-degree murder and felony burglary for entering the residence with the intent to kill. In the middle of the night, each student was attacked in their sleep.

The suspect is now in detention in Idaho, although he has not yet filed a plea, per ABC News.
