Newly unsealed documents from the Moscow Police Department reveal harrowing details about the killings of four University of Idaho college students — as well as chilling insights into the habits of their admitted murderer, Bryan Kohberger.

Kohberger on Wednesday received a life sentence without the possibility of parole for the November 2022 stabbings of Xana Kernodle, Ethan Chapin, Madison Mogen and Kaylee Goncalves, prompting police to release hundreds of documents they had previously kept confidential to protect the integrity of the court case.

The trove of files sheds new light on the investigation, detailing the brutal violence that victims experienced, the tactics police used to identify Kohberger as a suspect and the problematic history the former graduate student had previously had with women. They also bat down some of the theories spun up on social media by true crime fans, while also highlighting unknowns that continue to haunt police and the families of the victims.

Below are some of the revelations in these files — and the one key question we still don’t have an answer to.

The stabbings were extremely violent: Goncalves was disfigured. Kernodle was wounded more than 50 times as she fought back.
