Homicide 1992

In the early morning hours of Monday, September 7, 1992, Rhonda Anette Knutson was murdered while working the 9:00 p.m. to 5:00 a.m. shift at the Phillips 66 convenience store in Chickasaw County. The store was located six miles south of New Hampton on U.S. Highway 63 and one-quarter mile north of the junction of highways 63, #18 and #346. The store was open 24 hours a day, but no longer exists due to road construction.

It was determined that the probable cause of death was to have been from severe traumatic head injuries from a beating with a blunt object. The investigation included hundreds of interviews by deputies and agents from the Iowa division of criminal investigation along with the employment of a private investigator and several psychics.

The crime remains unsolved and the Chickasaw County Sheriff’s Office continues to ask for assistance for any information related to this murder.
