(KLZA / A.P.)-- A three-day search of more than 1,100 acres in an area east of Table Rock did not uncover the remains of a woman who has been missing for more than nine months, but the State Patrol said the search still helped the investigation.

Nebraska State Patrol Lt. Eric Jones said Sunday that investigators are now confident that Linda Dillard’s remains aren’t in the area that was searched, but they continue to believe she may have been the victim of a crime.

Throughout the three-day operation, teams searched more than 1,100 acres of land in and around the Table Rock State Wildlife Management Area, 24 miles of roadside ditches, 1.5 miles of river, 2 local farms, and a local lake area. The search team consisted of 44 law enforcement officers, 65 volunteers and support personnel, 15 mounted patrol teams, and 8 dog teams trained for human remains detection.

Numerous tips have been received through Nebraska Crime Stoppers and other avenues in recent days. Nebraska Crime Stoppers continues to offer a reward for information in this investigation. Tips can be made anonymously through Nebraska Crime Stoppers via the Nebraska Crime Stoppers website, the “P3 Tips” mobile app, or by calling 1-800-422-1494.

Dillard, 55, of Tecumseh, was last seen near Table Rock on June 16. No one has been arrested in connection with her disappearance.
