WICHITA, Kan. (AP) — A coroner says a woman whose body was found in a Kansas creek was strangled.

The body of 38-year-old Mary Ann Arnett was found in a creek south of Nickerson in June 2015.

The Hutchinson News reports Jamie Hatfield, of Hutchinson, is charged with premeditated first-degree murder, aggravated intimidation of a witness and conspiracy to commit murder in Arnett’s death. Her preliminary hearing is scheduled for next week.

Prosecutors say Hatfield and Jonathan Perser-Wilson were involved in Arnett’s death. Perser-Wilson was shot and killed by police during a confrontation the day after Arnett’s body was found.

Reno Capt. Steve Lutz of the Reno County Sheriff’s Office said Arnett and Hatfield had previously dated but when Arnett’s body was found, Hatfield was in a relationship with Wilson.
