An Idaho man has been sentenced to 2 years' probation after Idaho Fish and Game officials said he illegally killed a grizzly bear, the AP reports. The Idaho Department of Fish and Game announced the conviction on Monday, saying it was the first time the state has successfully prosecuted such a case since grizzly bears were protected under the Endangered Species Act in 1975. Normally the U.S. Fish and Wildlife Service handles those types of cases. Idaho Fish and Game says 23-year-old Kenneth Tyler Sommer, of Newdale, Idaho, was hunting for black bears in eastern Idaho when the grizzly was shot. Sommer told conservation officers he shot the grizzly after it charged him and his wife, but Idaho Fish and Game investigators said they found no evidence that the bear had ever charged.
