ST. CLOUD — Investigators have completed sifting through dirt taken from a St. Joseph farm near where Jacob Wetterling was abducted nearly 21 years ago.

The Stearns County sheriff’s office says items of interest were found and will be sent to forensic labs for additional testing.

Investigators executed search warrants at the farm on June 30 and July 1. Authorities took six truckloads of dirt and several other items from the farm.

The St. Cloud Times reports the sheriff’s office has not identified what those items are.

Jacob Wetterling was 11 years old when a masked gunman abducted him on Oct. 22, 1989. Jacob has been missing ever since, and there have been no arrests in the case.
