Wildlife workers outfitted the cat with a satellite tracking collar. Macho B was later euthanized at the Phoenix Zoo after vets determined he had acute kidney failure.
"This agency is committed to a thorough review of all facts and circumstances related to the original capture," said Game and Fish director Larry Voyles in the statement. "The department's investigative protocol requires careful protection of relevant information pending an outcome, but once the process concludes, we will disclose information to the extent allowable by law."
Wildlife workers are still waiting for more extensive test results on the jaguar to determine the extent of its illness.
