On the night of Saturday, May 9, 2026, 58-year-old Rodney D. Riall was found dead between a house and a detached garage in the 3000 block of North 200 West in Anderson, Indiana, having sustained several gunshot wounds. His son, 37-year-old Koty L. Riall, was found dead inside the detached garage with multiple sharp-edged wounds. Deputies from the Madison County Sheriff’s Department responded after 11:30 p.m. following a 911 call about a death investigation.

A 41-year-old Anderson man, John Christopher Worley, was arrested at the scene and initially booked on two counts of murder. Court documents and witness statements described a physical altercation among Worley, Koty Riall, and Rodney Riall, with observers saying Worley had been drinking and acting erratically and that Koty and Rodney engaged him before violence escalated.

The Madison County Prosecutor’s Office later declined to file formal murder charges, saying credible evidence supported a self-defense claim and that prosecutors could not disprove self-defense beyond a reasonable doubt. The prosecutor described Worley as having been attacked and on the ground beneath the two men when he used a knife, after which the father allegedly attacked him again and was killed. The office said it could revisit the matter if new evidence surfaced.

Did anyone in Anderson know the Riall family or see anything that night that might shed more light on what happened?
