The state of Arizona has fired an employee based on results of an internal investigation into the capture and death of what was the only known wild jaguar in the United States. The Arizona Game and Fish Department said that 40-year-old Thornton W Smith was a field biologist and had been with the agency for 12 years. He was involved in the placement and monitoring of traps used in a black bear and mountain lion research project that resulted in the initial capture of the jaguar called Macho B. The cat was found snared in one of the department's traps on February 18, 2009. It was euthanised less than two weeks later.
