Autopsies are scheduled Monday 09/13/2021 for Daniel and Pam Stephan at the University of Missouri in Columbia. Results of those autopsies may not be available for several weeks. The Union County Sheriff's Office has executed a search warrant and obtained several items of interest. Detectives will be traveling to South Dakota next week along with Boone County and Highway Patrol Investigators. Out of respect to the family, limited information is being released until the investigation is complete. Additional press releases will follow in the next several weeks. We want to thank the Boone County Sheriff's Office, Missouri State Highway Patrol, and Union County Sheriff's Office for their assistance in this joint investigation.
