On a 2015 job application acquired by Fox News Digital, Kohberger mentioned that he practiced boxing every day at Jesse Harris’ gym. He stated that this routine was instrumental in building discipline and keeping him physically fit.

Marie Bolger was originally called to appear in court, although her name was subsequently withdrawn from later documents. During a 2023 interview with the Daily Mail, Bolger described Kohberger as among her most exceptional students. Over a decade-long career as a criminology professor at DeSales University in Pennsylvania, she had endorsed only two students, including Kohberger, for Ph.D. programs.

After completing a master’s degree at DeSales, Kohberger proceeded to Washington State University, which is situated approximately 10 miles away from the off-campus residence where he is accused of murdering Kaylee Goncalves, 21, Madison Mogen, 21, Xana Kernodle, 20, and Ethan Chapin, 20.

Bolger told the outlet she had never met Kohberger in person and only taught him over email and Zoom during the height of the coronavirus pandemic. She helped him work on his graduate thesis, which centered on “how and why criminals commit their crime,” she said.

The other witnesses include Ann Parham, an adviser at the high school Kohberger attended, Ralph Vecchi, Maggie Sanders and Brandon Andreola. 

Prosecutors allege he left his DNA on a knife sheath detectives found with Mogen’s body. They also plan to introduce some of his DeSales homework as evidence that he was well-versed in concepts related to crime scene handling and the transfer of evidence.

Kohberger could face death by firing squad if convicted on any of the four charges of first-degree murder he faces. He is also charged with felony burglary in connection with the 4 a.m. home invasion attack.
