The charges filed Friday, Sept. 19, by the Warren County Prosecutor's office are the latest development since a volunteer, 26-year-old Jacob Barr, had his right leg surgically amputated just above the knee following a mauling by an 800-pound tiger on Aug. 3. The facility's owners, Kenneth and Sandra Smith, and Roy Elder are accused of lying to investigators by saying a pit bull attacked Barr. Wesa-A-Geh-Ya houses exotic animals outside of Warrenton. "In essence their actions and words interfered with the investigation and contributed to the tampering of the physical evidence," Warren County Prosecutor Mike Wright said. Wright doesn't anticipate any more criminal charges to be filed in the case. The Smiths and Elder are scheduled to make a court appearance on Oct. 20, court documents show. The Class A misdemeanor includes a term not to exceed one year and/or a fine not to exceed $1,000. According to probable cause statements filed on Friday, Elder, 27, of Warrenton, told Warren County Deputy Jeff Catron a white pit bull grabbed Barr's leg. After leaving the Smiths' property, Catron learned Barr had told his father he had been attacked by a tiger, not a pit bull. Catron made contact a second time with Elder, who said "he had provided false information about the attack because he feared the Smiths would lose custody of the animals." Sandra Smith also told a paramedic on the scene following that attack that she had injured her arm. Upon questioning by Catron, Sandra Smith "replied she had injured her arm by striking the pit bull that was attacking Barr." Kenneth Smith said he was not at the scene during the attack. He allegedly shot the tiger and moved the carcass to a residence located on Pin Oak Church Road. In the court filings, Smith told Catron "he had removed the animal from the scene because they had been under a tremendous amount of scrutiny and did not want the information regarding the attack to become public." Sandra Smith told The Associated Press earlier this week Elder, Barr and two others camped out on their 17-acre property the night before the incident. She said Elder offered to help care for the animals with assistance from Barr. She added she never gave Barr or Elder permission to go into the cages. On Aug. 27, Barr filed a lawsuit against the animal facility and the Smiths alleging Elder sprayed the tiger in the face with water or vinegar from a garden hose before the attack. Since the incident involving Barr, nearly all of the exotic animals located at Wesa-A-Geh-Ya have been relocated to other facilities located in Colorado, Oklahoma and other states. In its heyday, the Wesa-A-Geh-Ya facility charged admission to allow spectators to view the animals. The Smiths, however, surrendered their license to exhibit the animals and it was later revoked after the U.S. Department of Agriculture found violations at the site, including gaps in fencing where the lions and tigers lived.
