A Rockford man has been convicted of torturing and killing his own dog with his truck in an incident that unfolded in broad daylight on Christmas Day two years ago. Jon Duncan was found guilty of two counts of animal torture and two counts of aggravated animal cruelty in connection with the death of his black Labrador mix, Duke.
The case dates back to December 25, 2024, when officials were called to the 1400 block of Linda Avenue in Rockford after reports that a dog had been hit by a truck. According to MyStateline, Duncan initially told authorities the dog had gotten loose and he struck it by accident. But that account didn't hold up once investigators started talking to neighbors.
One witness told Winnebago County Animal Services that she saw Duke running loose with Duncan chasing him at high speeds in his truck, per the outlet's reporting. Another witness told officials that Duncan had been trying to give the dog away earlier that same day, raising questions about what happened in the hours before Duke was struck. Court records cited in the same report state that Duncan swerved out of his lane toward the dog and hit him without slowing down.
Trial Testimony Describes a Second Strike
At trial, the account grew more disturbing. Rockford News First reports that two witnesses testified they saw Duncan chase Duke with his truck, swerve to hit the dog, and then run him over a second time. Prosecutors told the court that part of the incident was captured on surveillance video from a nearby home.
Winnebago County State's Attorney J. Hanley said Duncan delayed taking the dog for veterinary care, a delay that resulted in Duke's death, according to the same outlet. Duke ultimately died from his injuries, officials said.
Guilty Verdict and a Sentencing Date Still to Come
Judge John Gibbons presided over the proceeding that ended in Duncan's guilty finding on two counts of animal torture and two counts of aggravated animal cruelty. Duncan is due back in court on January 15, 2027, for the next phase of the case.
Reporting on the potential penalty Duncan faces is not consistent. MyStateline's account states that Duncan faces up to 8 years in prison, while Rockford News First reports a maximum sentence of 16 years in prison followed by a term of mandatory supervised release. The discrepancy between the two accounts remains unresolved.
Animal cruelty cases involving vehicles have drawn stiff penalties elsewhere in Illinois. In a separate case out of Washington Park, a man was sentenced to 10 years in prison, according to stltoday.com, after he left a dog in the heat, dragged it from a vehicle, and abandoned it in a field. That case underscores how seriously Illinois courts have treated deliberate harm to animals in recent years.
Reports have also varied on Duncan's age at the time of the Christmas Day incident. MyStateline identified him as 54 years old at the time, while WIFR reported he was 52 when responding officers located him after the incident.
