Four Lives Lost: The Bryan Kohberger Idaho Murders Case

In the early hours of November 13, 2022, four bright college students were brutally murdered in their sleep—a crime that would grip the nation and expose the dark mind of a killer hiding in plain sight.

When Kaylee Goncalves, Madison Mogen, Xana Kernodle, and Ethan Chapin were found stabbed to death in their off-campus home in Moscow, Idaho, investigators faced a baffling case with no obvious motive, no witnesses, and a killer who seemed to vanish into the night.

But the perpetrator made one fatal mistake: he left behind a knife sheath containing his DNA.

Four Lives Lost takes you inside the exhaustive investigation that used cutting-edge genetic genealogy to track down Bryan Kohberger, a criminology PhD student who had been studying the very techniques used to catch him. Through unprecedented access to police documents, court records, and family interviews, author Rick Stupart reveals:

• The victims' final hours and the lives cut tragically short • How investigators used cell phone data and surveillance to build their case
• The DNA breakthrough that cracked the case wide open • The killer's disturbing behavior and failed attempts to cover his tracks • The families' fight for justice and the community's path to healing

From the crime scene to the courtroom, this is the definitive account of a case that shocked America—and the forensic investigation that brought a killer to justice.
