"An intruder entered this home and attacked two young children, along with their mother. My babies are dying! They're dead! Oh, my god!" A mother's 911 call seemed genuine, but blood spatter analysis and behavioral profiling told a different story.
On June 6, 1996, police in Rowlett, Texas received a call from Darlie Routier, claiming an intruder had murdered her two sons, 6-year-old Devon and 5-year-old Damon. Investigators doubted her story after analyzing blood spatter, profiling her behavior, and examining her 911 call. The evidence proved she killed both children with a kitchen knife, inflicted wounds on herself, cleaned the scene, and fabricated the intruder story. Routier was convicted of first-degree murder and sentenced to death.
