Grayden Denham, the 24-year-old man, whose grandparents, sister, and infant nephew were found dead at a home in Edgerton, Mo., in February has now been charged with four counts of 1st degree murder, 4 counts of armed criminal action, animal abuse, arson in the 2nd degree and tampering with physical evidence.
(...) Prosecutors said Denham stole the family car from his grandparents, Russell, 82, and Shirley, 81, Denham. Those two, along with Graydens sister, Heather, 32, and 3-month-old nephew, Mason, were found dead at a home in Edgerton, Mo., on Feb. 20.
Days later, police found Denham wandering naked in Arizona. They then located Russell and Shirley Denham's brown Nissan parked at a motel parking lot. Clothes were found outside the car, and Denham's wallet was inside the pants.
