() The latest court document dump in the Idaho college slayings case suggests defendant Bryan Kohberger bought a black face covering 11 months before he allegedly murdered four students as they slept.

Prosecutors say records show Kohberger purchased a black balaclava Jan. 10, 2022, at a Dick’s Sporting Goods while he was in Pittsburgh. The stabbing deaths of Kaylee Goncalves, Madison Mogen, Xana Kernodle and Ethan Chapin occurred Nov. 13 in Moscow, Idaho. THAT CAN’T BE RIGHT …

State prosecutors have previously disclosed they have online shopping records indicating Kohberger bought the murder weapon a combat-style knife as well as a sheath and sharpener eight months before the killings. A sheath with DNA linked to Kohberger was found at the crime scene.

Introducing information about the face covering could bolster the account of a surviving roommate who told police she saw a bushy-eyed stranger in the house who was wearing a black mask.

Who is Bryan Kohberger?

Kohberger was a graduate student at Washington State University in nearby Pullman, Washington. He has been charged with first-degree murder, has pleaded not guilty, and is expected to go to trial in August.

Prosecutors say he drove the type of white Hyundai Elantra that was seen in the area during the time of the killings.

Smiling selfie disclosed earlier

Previous court documents also showed a selfie that Kohberger is said to have taken the morning of Nov. 13, 2022, hours after the killings. In the picture, Kohberger is seen smiling and giving a thumbs-up, possibly in front of a tiled shower.

Prosecutors have indicated they would like to use the photo of Kohberger to show jurors he has the type of eyebrows described by the roommate.
