Investigator disputes connection between missing 11-year-old and Mollie Tibbetts' murder Iowa DCI's Mitch Mortvedt said the only thing in common is that both Xavior Harrelson and Mollie Tibbetts lived in Poweshiek County. Author: Lakyn McGee Updated: 6:57 PM CDT July 20, 2021 DES MOINES, Iowa — Those with any information surrounding Xavior Harrelson's disappearance are encouraged to contact the Poweshiek County Sheriff's Office at 641-623-5679. It's been two months since 11-year-old Xavior Harrelson went missing from his home in Poweshiek County, and while the cases seem to be similar, the Iowa Division of Criminal Investigation believes the boy's disappearance isn't connected to the murder of Mollie Tibbetts.
