Four Lives Lost

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.
