He was arrested on suspicion of the murders a month later. Though to this day he has never provided a motive for the killings, Kohberger ultimately plead guilty to four counts of first-degree murder and one count of felony burglary in exchange for avoiding the death penalty.

Last month Kohberger was handed four consecutive life sentences for his crimes.

According to new police reports, teaching staff at Washington State University had raised pointed concerns about Kohberger’s behavior just weeks before he committed the aforementioned murders.

One faculty member at WSU – where Kohberger was studying a criminology PhD course – suggested that the now-30-year-old could use his position to stalk and abuse future students should he ever become a professor.
