WAUSEON, Ohio (AP) — Authorities believe they've found the remains of a missing Ohio college student whose bicycle was discovered in a cornfield this week.

Fulton County Sheriff Roy Miller told reporters at a Saturday news conference that investigators found the remains Friday evening in rural northwest Ohio. An autopsy has yet to be completed. Authorities did not release details on how she might have died, and did not take any questions.

Twenty-year-old University of Toledo student, Sierah Joughin, was last seen riding her bike Tuesday near Metamora.

Authorities on Friday arrested 57-year-old James Worley, of Delta, on an abduction charge related to her disappearance.

The sheriff said he anticipates additional charges will be filed in the case.

Worley has requested an attorney who has represented him previously. That attorney declined to comment.
