The mass execution of 48 exotic animals on Tuesday evening has caused outcry from animal lovers across the country and now the mayor of Zanesville, Ohio, is getting hate mail wrongly blaming him for the killings, RadarOnline.com has exclusively learned.

"I’ve had a lot of people calling and complaining, and some really nasty e-mails," Mayor Howard ‘Butch’ Zwelling told RadarOnline.com in an exclusive interview.

As RadarOnline.com previously reported, Terry Thompson opened the cages and gates of the 56 exotic animals that he kept on his ranch -- including bears, cheetahs, wolves, lions, camels, giraffes and a white Siberian tiger -- prior to giving himself a fatal, self-inflicted gun shot wound.

An autopsy revealed that within a minute of his death he was bitten on the head by a large cat, most likely a Bengal tiger.
