Todd Moon killed his parents and himself in a fit of rage Christmas morning.

That’s the conclusion of an investigation into the deaths Todd Moon, 48, Donald, Moon, 84, and Joyce Moon, 81, Hamilton County Sheriff Mark Bowen said Wednesday.

“Clearly the holidays can be a time of stress for some people, but there are avenues you can reach out to for help, so something like this doesn’t have to happen,” Bowen said.

Bowen and Hamilton County Coroner John Chalfin reported their findings, following two days of investigation.

Bowen said The Moon’s daughter received a call Christmas afternoon from Todd Moon, asking her to come to the Moon residence, 11200 block of 191st St., Noblesville, and pick up his two children, twin 8-year-olds.

The sister told investigators when she arrived she found Todd angry, but could not determine why.

“She really couldn’t tell what the problem was. She tried to calm Todd down, but was never able to figure out what the situation was,” Bowen said.

At one point Joyce Moon stepped out of another room, and Todd Moon began shooting at her.

“(The sister) saw Todd shoot at his mother,” Bowen said.

The sister said Todd Moon went to a back bedroom and began firing shots at his father.

The sister took the children and left the house, but before driving away, heard one last gunshot.

Bowen said the sister then drove to the Noblesville Fire Station at 191 Street and Ind. 37 to summon help.

Noblesville Police were the first to arrive at the residence and found Joyce Moon in the front hallway, Donald Moon in a rear bedroom, and Todd Moon was found near the kitchen.

Chalfin said preliminary autopsy findings show both Donald and Joyce Moon died from multiple gunshot wounds, and Todd Moon died from a single, self-inflicted gunshot wound to the head.

The autopsies were conducted by Dr. T.J. Sozio, a forensic pathologist, Wednesday morning.

Bowen said a search of records indicated the Sheriff’s Office had not responded to the residence for any calls other than a potential telephone fraud several years ago. There were no criminal charges in the backgrounds of any of the individuals involved, nor was there a known history of mental illness or domestic violence. No note was found, and detectives are still working to ascertain what may have led to the incident or the cause of the argument.

Although toxicology results are pending, detectives do not believe alcohol or drugs were involved in the incident.

Children living at the residence are receiving care from the Indiana Department of Child Services and are staying with family members.
