Arizona Game and Fish officials have completed operations in Prescott as the fourth mountain lion was found and killed Saturday. The mountain lions had been in the community over the past few weeks and reportedly killed several pets. Officials say the fact that they continued to be seen in proximity to homes and people, appeared to be less fearful of people, and had recently been observed exhibiting aggressive or unacceptable behavior toward people, categorized them as a public safety threat. Early Saturday morning wildlife officers observed the fourth lion had killed a domestic cat and was in the same area as previous pet attacks and aggressive human interactions. Immediate intervention was taken; the lion was lethally removed to ensure the safety of area residents. The first lion was killed after attacking a dog and acted aggressively toward the owner back on May 21st. Two other mountain lions in the pack, were also killed one on Tuesday and the other on Wednesday. Wildlife officials say because the behavior exhibited by the lions was considered a public safety threat, relocation was not an option.
