ALBUQUERQUE, N.M. (AP) - U.S. wildlife managers are investigating the death of a Mexican gray wolf found last month in Arizona. Officials with the wolf recovery team announced the death Thursday but didn't provide any details about how the endangered animal might have died or exactly where it was found. The latest death follows three others that were reported in January, all of which were in Arizona. A subspecies of the Western gray wolf, Mexican wolves have faced a difficult road to recovery that has been complicated by politics and conflicts with livestock. The latest survey documented at least 163 wolves in the wild in Arizona and New Mexico.
