Chet K. Neilson


A 31-year-old St. Anthony man has been arrested in relation to a two-year-old rape case in Teton County, according to authorities.

Chet K. Neilson is charged in connection to the rape and battery of a 26-year-old woman in the Victor City Park on Aug. 4, 2017, a Teton County Sheriff’s Office news release said.

The two-year rape investigation was led by Detective Sgt. Andrew Foster of the Teton County Sheriff’s Office. A criminal complaint filed by Teton County Prosecuting Attorney Billie Siddoway says the victim resisted the rape, but she was overcome by force or violence. The complaint also alleges that Neilson inflicted great bodily injury to the victim.

On Aug. 4, 2017, the victim returned to the Victor City Park to retrieve her bicycle after attending Music on Main when she was attacked from behind, forced to the ground, and raped by an assailant unknown to her.

According to the news release, earlier this month, Foster received an investigative lead pointing to Neilson.

With the assistance of the Idaho State Police and Fremont County Sheriff’s Office, Foster obtained a discarded DNA sample from Neilson. On Aug. 22, 2019, the Idaho State Police Forensic Laboratory confirmed that the DNA profile from Neilson matched the profile of a DNA sample obtained following the rape.

The charge of felony rape carries a potential penalty of life in prison and a fine up to $50,000. The charge of felony battery carries a potential penalty of 20 years in prison with a fine up to $50,000.
