A hand-drawn sketch from a survivor of a home invasion massacre that killed four slain University of Idaho students shows the “ski-mask”-like face covering a male intruder wore when he entered her off-campus house in November 2022 and killed her friends – and it looks like a balaclava the suspect allegedly bought months earlier.

While the roommate, identified in court documents only as DM, said she did not know the suspect Bryan Kohberger, and did not recognize him even after being shown his mugshot following his arrest, she told investigators she saw a masked man with “bushy eyebrows” and a build similar to Kohberger’s in her house minutes after the murders.

In a separate filing also unsealed Thursday, prosecutors alleged that Kohberger bought a black balaclava from a Dick’s Sporting Goods store in January 2022.

The victims were Madison Mogen, 21, Kaylee Goncalves, 21, Xana Kernodle, 20, and Ethan Chapin, 20. The three young women were all roommates. Chapin lived nearby and was dating Kernodle.

Kohberger’s trial on four charges of first-degree murder and another of burglary is set to begin on Aug. 11. Jury selection is scheduled for July 30.

A previous judge entered not guilty pleas on Kohberger’s behalf at an arraignment in May 2023. He could face the death penalty if convicted.
