PINE RIDGE, S.D. - Authorities are searching for a 35-year-old Norfolk man with a long criminal history after he allegedly led police on a high-speed chase late last week.

Cody Dittman has been on the run since Thursday. According to law enforcement, the pursuit began Friday on the Pine Ridge Reservation in South Dakota, where Dittman is accused of swerving his vehicle toward officers. One officer fired a shot during the encounter. The chase then continued into Nebraska, ending in a remote part of Dawes County.

By Sunday night, the Oglala Sioux Tribe Department of Public Safety issued a public alert warning residents that Dittman may be back in the Pine Ridge area. Officials urged people to secure their homes and vehicles.

Dittman is facing three felony charges in Madison County, filed just last week. The charges include assault by strangulation or suffocation of a pregnant victim, attempted false imprisonment in the first degree, and third-degree assault.

According to an arrest affidavit, Dittman assaulted a woman in Norfolk who is pregnant with his child. He allegedly tried to strangle her, hit her, and attempted to forcibly remove a facial piercing using his teeth. The affidavit also states that Dittman followed the woman in her vehicle and sent messages to the woman’s parents, saying he’ll leave their daughter alone, but don’t call the police.

Tribal authorities say he’s also being investigated for a firearms-related complaint on the reservation.

Dittman has an extensive criminal history dating back to his teenage years. He has prior convictions for assault, drug possession, disturbing the peace, and theft. In 2013, he was sentenced to six months to a year in prison for assaulting someone while already behind bars. The following year, he received a six-to-eight-year sentence for another assault. In 2017, he was again convicted—this time for assaulting a correctional officer with a dangerous instrument. More recently, he was found guilty of driving offenses in 2021 and 2025.

Law enforcement officials are urging the public not to approach Dittman if seen. Anyone with information about his whereabouts is asked to call 911 immediately.
