The owner of a wild-animal preserve -- that housed as many as 48 wild and exotic animals -- opened the pens and cages of his menagerie before killing himself, authorities in Zanesville, Ohio said during a news conference Wednesday morning. The property owner, Terry Thompson, opened the cages and gates of the animals -- including bears, cheetahs, wolves, lions, camels, giraffes and a white Siberian tiger -- prior to giving himself a fatal, self-inflicted wound, police said, adding they were waiting on autopsy results. Three animals are unaccounted for -- a lion, a bear and a monkey -- police said in a preliminary estimate. Authorities shot and killed about 30 of the animals Tuesday, and were under orders to shoot to kill during overnight efforts to round up the animals. What a weird way to go out. PETA, where you at on this one?
