On May 30, 1998, the body of 35-year-old Raymond Kreitzer was found in the Mad River near the Ohio Edison Plant in Springfield, Ohio. Kreitzer had been reported missing by a family member on December 30, 1997; local canoeists discovered his body near the mouth of Buck Creek and investigators determined he had been in the water for some time and had sustained multiple gunshot wounds, leading authorities to classify his death as a homicide.

Kreitzer lived in a camper in a wooded area along the Mad River, sharing the camper with John Edward Campbell. Campbell had been found earlier that year, on February 13, 1998, in the same area of the river and also had multiple gunshot wounds. The proximity of their living situation and the similar circumstances of their deaths has prompted investigators to consider connections between the two unsolved homicides, which remain open.

Anyone with information about the murders of Raymond Kreitzer or John Campbell is asked to contact local law enforcement or the Bureau of Criminal Investigation.
