ST. LOUIS (AP) — The owners of an exotic animal park and one of its board members have been charged with evidence tampering for allegedly trying to cover up a tiger attack on a volunteer.

The owners of Wesa-A-Geh-Ya in Warren County, Kenneth and Sandra Smith, and board member Roy Elder initially led the sheriff's department to believe that a pit bull, not a tiger, attacked volunteer Jacob Barr, who had part of his leg surgically amputated following the Aug. 3 mauling.

The three were charged with evidence tampering, a misdemeanor, on Friday.
