FBI and Grimes County officials aren't saying much about an on-going investigation.
Thursday, authorities acted on a tip, but found nothing in the Roans Prairie area after an extensive search. The tip revolved around a four-year-old missing persons case from another state.
Both the FBI and Grimes County authorities confirmed the investigation continues in the area, including interviews with people of interest surrounding this case.
Further details were withheld by authorities due to the on-going nature of the case.
