BIG BEND NATIONAL PARK (February 6, 2012)—Rangers at Big Bend National Park officials were searching Monday for a mountain lion that attacked and injured a 6-year-old boy as he walked with three other people.

Park spokesman David Elkowitz said the boy, who wasn't identified in a park statement Monday, was treated for puncture wounds and scratches and later released from a hospital in Alpine.

Elkowitz says the young boy was walking Sunday evening near the park's lodge with three other people a "young lion in very poor condition” attacked him.

Rangers began evacuating trails and campsites early Monday, closing areas including the Chisos Basin, Window Trail, the Pinnacles, Boulder Meadow and Juniper Flats.

Elkowitz says the animal that attacked the boy will be killed if it’s found.
