The LaNell Barsock case.

In 2010, LaNell Barsock was found dead inside her California home after a woman covered in blood rushed into a sheriff’s station claiming to have discovered the body.

But as investigators uncovered lies, hidden relationships, and a carefully staged crime scene, the truth became far more disturbing than anyone imagined. Tonight, we dive deep into one of the most deceptive murder investigations in recent memory — a case where the witness may have known far more than she claimed.
