A Pennsylvania court has unsealed the Dec. 30 search warrant in the Idaho student murders case, which led to the arrest of suspect Bryan Kohberger at his parents' house in the Pocono Mountains nearly seven weeks after the slayings.

Police seized a number of new items at the home, including medical-style gloves, a black sweatshirt, size 13 Nike sneakers, and they also took a buccal swab.

Kohberger, a 28-year-old criminology Ph.D. student at Washington State University during the attack, is accused of ambushing four University of Idaho students in the middle of the night on Nov. 13, 2022. The schools are about seven miles apart.

The attack killed 21-year-olds Kaylee Goncalves and Madison Mogen along with their 20-year-old housemate, Xana Kernodle, and her boyfriend, Ethan Chapin, also 20. The students were apparently ambushed as they slept inside an off-campus apartment in Moscow, Idaho.

According to court documents, police found a Ka-Bar knife sheath near Mogen's body and recovered a DNA sample from the snap.

That DNA was a familial match for another sample taken from the trash at the Kohberger family residence in Albrightsville, Pennsylvania. After tracking Kohberger across the country, police said they believed that his vehicle, which was allegedly spotted at the crime scene on the night of the slayings, was parked in a two-car garage on the west side of his parent's house.

Police say his vehicle arrived at his parents' house on Dec. 16, and investigators spotted him walking around outside on Dec. 27. He left his parents house on Dec. 28, and investigators observed him traveling to various locations in Monroe County.

After a tactical raid at his parents' home on Dec. 30, police searched the house, an attached garage, a shed and his car. Other items they seized include a silver flashlight and several other articles of clothing.

While the warrant application specifically asks for permission to seize and search Kohberger's devices, the inventory of seized items doesn't mention any. However, investigators did note in the filing that his cellphone appeared to be in the vicinity.

Kohberger is being held at the Latah County Jail in Moscow, Idaho, without bail.

Authorities have not publicly established a motive for the attack but allege that Kohberger stalked the victims' house at least a dozen times before the slayings and returned once more to the scene hours later.
