LOS ANGELES (AP) — Officials believe P-22, a wild mountain lion that prowls a sprawling Los Angeles park, made a meal of a koala found mauled to death at the city's zoo.Zoo director John Lewis said this week that workers found the koala's body outside its pen March 3. The big, 7-year-old male cougar was spotted on surveillance video from the same night.Zoo workers are now taking extra precautions, such as locking up smaller animals in barns at night.
