ZANESVILLE, Ohio (AP) — An Ohio sheriff says the last of dozens of exotic animals set free by its owner may have been eaten by one of the others.

The sheriff's office in eastern Ohio's Muskingum County told The Associated Press that the search for a missing monkey was still active. But he's told WCMH-TV that the monkey may have met the same fate as another, which was eaten by a big cat.

Authorities say animal owner Terry Thompson killed himself Tuesday evening after opening the cages at his farm near Zanesville.

Lions, tigers, bears and other animals began scattering and police hunted them down. Eventually about 48 were killed.

Animal rights advocates say there was little police could do to save them.
