Stanley Simon, 39, was found dead inside his Springfield, Missouri home during a wellness check on October 20, 2020. Deputies from the Greene County Sheriff’s Office discovered signs of a disturbance; an autopsy later confirmed Simon had been shot in the upper chest and neck, and his death was ruled a homicide.

Investigators reported the house had been ransacked and several items stolen, including Simon’s 2004 Chevrolet 3500 dually truck, multiple firearms, a dirt bike, and two chainsaws. Four days after the killing police located the truck; the driver fled and abandoned the vehicle, which became key evidence. Authorities identified three suspects: 25-year-old Riley Collier, 18-year-old Patricia Davis, and 40-year-old Michael Stauffer. Collier was described as the shooter, armed with a .223-caliber rifle, and the trio had gone to the home intending to burglarize it.

Plea deals in the case resulted in guilty pleas to burglary and murder-related charges; sentences were imposed for each defendant. Does anyone have information about Simon, his property, or the days around October 20, 2020?
