A Sioux Falls woman whose body and car were found in Hanson County died of hypothermia. 60-year old Kay Flittie went missing on April 5th. She was supposed to travel from South Dakota to Arkansas to visit a relative. Her car was found on I-90 near exit 352. This past Saturday, a 150-person search team consisting of both law enforcement officials and volunteers searched for Flittie. Her body was found about three miles east of where she was last seen alive in Hanson County. An autopsy performed on Monday in Rapid City showed that there was no foul play involved in Flittie’s death.
