"Contrary to their denials, employees of the Arizona Game and Fish Department intentionally snared the last known jaguar in the Southwest last year, a report by the federal government says.

Wildlife advocates and politicians had demanded a federal investigation of the capture of the male cat, nicknamed Macho B, which was freed soon after he was snared but later recaptured and euthanized because he was ailing. Many described the department’s account of his capture and death as suspicious.

But Arizona’s Game and Fish Department called the document incomplete and denied that it was to blame.

In February, the 118-pound jaguar, which then appeared to be in fine health, was captured in a leg-hold snare in the mountains near Nogales, Ariz. His canine tooth was broken as a result. He was tranquilized, equipped with a radio collar and released.
Days later it was found that Macho B was not moving, and he was recaptured and brought to the Phoenix zoo. Veterinarians there said he was suffering from irreversible kidney failure and euthanized him."
