White, three-month-old Mason Gage Denham was the youngest victim in a quadruple homicide that devastated a family in Edgerton, Missouri, on February 19, 2016. Emergency responders were initially called to a residence on Buena Vista Road to extinguish a house fire, but the scene quickly revealed a far more sinister reality. Mason's body was discovered in the front yard of the burning property along with the remains of his mother, thirty-two-year-old Heather Abree Denham, and his
great-grandparents, eighty-two-year-old Russell Denham and eighty-one-year-old Shirley Denham. The intense flames had engulfed the home, yet the investigation determined that the fire was set intentionally to cover up the violent deaths of the four family members.
Forensic examinations later confirmed that Mason and his relatives had not died from the fire itself but had been shot before their bodies were set ablaze. In a chilling detail that prosecutors later highlighted, pennies were found placed on the eyes of the victims. This ritualistic placement extended even to the family dog, which had also been killed at the scene. Investigators connected this specific behavior to the suspect's fascination with the film 'The Boondock Saints,' in which vigilantes place coins on the eyes of the deceased. The brutality of the crime and the methodical nature of the cover-up shocked the small Platte County community and launched an immediate manhunt for the person responsible.
Suspicion quickly fell on Grayden Lane Denham, Mason's uncle and the brother of Heather Denham. Grayden had been living at the residence with his grandparents and sister but was missing from the scene when authorities arrived. Witnesses and family members reported that Grayden had a history of drug use, specifically methamphetamine, and had been involved in heated arguments with his grandfather shortly before the murders. The investigation revealed that he had purchased gasoline cans and filled them with fuel on the day of the killings, evidence that directly linked him to the arson.
Two days after the bodies were found, law enforcement located Grayden Denham in Seligman, Arizona, more than a thousand miles away from the crime scene. He was driving his grandfather's stolen Nissan Versa and was taken into custody while walking naked in the town. Inside the vehicle, investigators found clothing with gunshot residue and traces of the accelerant used to start the fire. He was extradited back to Missouri to face charges, where prosecutors built a case based on forensic evidence and testimony regarding his unstable behavior and conflicts with the family.
During the legal proceedings, the defense attempted to navigate the overwhelming evidence, but the jury ultimately found Grayden Denham guilty on all counts. He was convicted of four counts of first-degree murder, four counts of armed criminal action, animal abuse, second-degree arson, and stealing. In late 2020, a judge sentenced him to four consecutive life terms without the possibility of parole, ensuring he would never be released. An additional one hundred and fifteen years were added to his sentence for the related felonies, bringing a final legal resolution to the tragic loss of infant Mason and his family.
