PESCADERO, Calif. (AP) — Authorities say a quick-thinking custodian safely confined a mountain lion in an empty classroom after it entered a Northern California high school. The San Mateo County Sheriff’s Office says no students or staff were at Pescadero High School south of San Francisco yet when the big cat strolled onto campus. An official says the animal, estimated to be about 40 pounds, appeared “lost and scared.” The U.S. Fish and Wildlife Service was called to humanely remove the big cat and return it to its natural habitat. Pescadero is a small coastal community about 35 miles south of San Francisco.
