ZANESVILLE, Ohio (Reuters) - Dozens of exotic animals including tigers, lions and bears were let loose on Ohio farmland by their owner before he committed suicide, sparking a shoot-to-kill hunt in which 49 of the wild beasts, including 18 endangered Bengal(孟加拉) tigers, were killed.
As the huge animals roamed(漫游) inside and outside the 73-acre (30-hectare) farm near Zanesville in eastern Ohio, schools were shut and panicked residents were told to stay inside on Wednesday.
Authorities killed 49 of the 56 animals, some at close range, including the tigers, six black bears, two grizzlies(灰熊), two wolves and 17 lions, said Muskingum County Sheriff Matt Lutz.
A macaque(短尾猿) monkey, possibly carrying the Herpes B virus, remained at large. A wolf Lutz said was on the loose actually had been killed on Monday night, the sheriff's office said.
One of the escaped big cats reached an interstate highway and was hit by a car. Authorities posted electronic warning signs, "Caution Exotic Animals" for motorists.
"We are not talking about your normal everyday house cat or dog. These are 300-pound Bengal tigers that we had to put down," Lutz said. "I gave the order ... that if animals looked like they were on their way out, they were put down."
The dead animals have been buried on the farm, he said. Survivors were taken to the Columbus Zoo, including three leopards(美洲豹), a grizzly and two macaque monkeys.
Owner Terry Thompson, 62, who had been charged with animal cruelty 11 times since 2004, was found dead from an apparently self-inflicted wound when authorities went to the farm on Tuesday after reports of animals running free, Lutz said. They found gates and animal pens open, but no suicide note.
"There were animals running loose outside the fenced area," he said. Some, including primates(灵长类的动物), were captured at the farm.
Lutz said animals kept at the farm included many types of big cats such as cheetahs(印度豹), mountain lions and leopards, in addition to lions and tigers.
Authorities said they had received about 35 calls about the menagerie(动物园) over the years, ranging from animals running loose to animals not being treated properly, Lutz said.
"We've handled numerous complaints here, we've done numerous inspections here," he said. "So this has been a huge problem for us for a number of years."
There were complaints that Thompson left horses undernourished(营养不良的,半饱状态的), then fed them to lions when they died, said Larry Hostetler, executive director of the Muskingum County Animal Shelter.
However, he met the bare minimum requirements for keeping the animals, he said.
Thompson was released last month from federal prison on a firearms conviction. Lutz said Thompson's wife, Marian, was no longer living at the farm. She will return to care for some remaining horses, he said.
DANGEROUS ANIMALS
Lutz described the freed animals found as "mature, very big and aggressive."
The sheriff said they tried to shoot some of the animals with tranquilizer(镇定剂) guns but encountered problems.
"We just had a huge tiger, an adult tiger that must've weighed 300 pounds that was very aggressive," Lutz said. "We got a tranquilizer in it and this thing just went crazy."
Barbara Wolfe, a veterinarian, said she shot a tranquilizer dart into the tiger, but it got up and charged(攻击) her from 15 feet away. A deputy shot the tiger dead.
"I've never been in fear of my life more than then," Wolfe said. She works at The Wilds, a refuge not far away from Zanesville that keeps exotic animals like rhinos and giraffes.
Lutz said he issued a shoot-to-kill order on Tuesday evening and stationed officers on Interstate 70 about a mile west of the Zanesville city limits to prevent animals from crossing.
He said he also ordered the schools closed on Wednesday. "We didn't want kids standing at the bus stop" while wild animals were loose, Lutz said.
Jack Hanna, director emeritus of the Columbus Zoo, told the news conference Lutz and his deputies did the right thing.
"These are dangerous animals," Hanna said. "If you had 18 Bengal tigers running around these neighborhoods, you wouldn't have wanted to see what would have happened."
