LEWISTOWN — Troy Chisum was backing away from a house in rural Avon when he was fatally shot, a Fulton County prosecutor said Thursday.

State's Attorney Justin G. Jochums said Nathan Woodring, 42, of Avon allegedly shot the Fulton County Sheriff's deputy with a shotgun before barricading himself in the house for the next 19 hours. At some point, Woodring allegedly shot at a robot that police had sent into or near the house as way to see what was going on.

Those were just some of the revelations during a brief court hearing Thursday in Fulton County Circuit Court, where Woodring was charged with one count of first-degree murder in connection with the deputy's death. Bond was set at $5 million.

Because he's accused of using a firearm to kill Chisum and because Chisum was a sheriff's deputy, Woodring faces up to life in prison if he is convicted. Also, he faces a minimum sentence, if convicted, of 45 years behind bars, due to the fact that a firearm was used.

A grand jury will now likely hear the case within the month, and then Woodring, if he's indicted, would appear back in court to enter a plea on the case, which would then be set for trial. Any trial, however, given the nature of the charges, would likely be next year at the earliest. Woodring is scheduled to next appear in court on July 11 for a first appearance with his attorney.

In a phone interview after the hearing, Jochums said more charges could be coming.

Chisum had gone at about 2 p.m. to the house, located in the 5250 E. Troy Road, which is about an hour due west of Peoria, regarding what has been described as a battery and a disturbance. He was one of four people at the house. Reportedly, he began to approach the house when he saw Woodring on the porch. Shots rang out, and Chisum began to back up and was then shot.

Nobody else was injured in the shooting. It wasn’t clear if the residence in northwest Fulton County, about 45 miles west of Peoria, was Woodring’s.

Chisum had been with the sheriff’s office about 4½ years. A memorial fund has been established for his family at Mid America National Bank in Canton, and a Deputy Troy Chisum Memorial Fund has been established on GoFundMe.

Woodring had two prior felony drug-related convictions and a few misdemeanors in Fulton County, according to court records.
