CORVALLIS, Ore. (AP) -- A $5,000 reward has been offered for information leading to an arrest in the disappearance of a prize sheep from the Benton County Fair.

The ewe named Millie was raised as a 4-H project by 13-year-old Michael Lorain, of Philomath. She vanished from the fairgrounds in early August after winning her division in the livestock competition.

Michael Lorain's grandparents, Paul and Lola Skirvin, put up the reward money in hopes the thief would be brought to justice.

The Benton County Sheriff's Office is investigating.
