On the night of February 19, 2016, a house fire on Buena Vista Road near Edgerton, Missouri, revealed a massacre. Four family members were found outside the burning home, each shot to death before the structure was set ablaze: 32-year-old Heather Ager, her three-month-old son Mason Schiavoni, and her grandparents, 82-year-old Russell Denham and 81-year-old Shirley Denham. The family dog, Jack, was also found shot and burned. Investigators described the killings as execution-style and reported pennies had been placed on the victims’ eyes — an act later linked in court to the suspect’s fondness for the film The Boondock Saints.

Authorities identified 24-year-old Grayden Lane Denham, Heather’s brother and the grandchildren’s grandson, as a suspect after he was missing from the scene and his grandmother’s Nissan Versa was taken. The vehicle was found in Arizona and Grayden Denham was arrested there; clothing he left behind reportedly tested positive for gunshot residue and fuel. Prosecutors said tensions and methamphetamine use preceded the killings and that gasoline cans had been purchased and filled shortly before the incident.

Grayden Denham was extradited to Missouri and charged with multiple counts including first-degree murder, armed criminal action, arson, animal abuse, and stealing. The case centers on how a rural family was targeted and the motive behind such extreme violence.
