A lone gray wolf padded quietly into Los Angeles County before dawn on Saturday — and made history. State biologists say the female wolf may be the first documented in Southern California in 100 years, after the apex predators were wiped out across the state by eradication campaigns aimed at protecting livestock. The last known wild wolf in California was shot on June 12, 1924, by federal trapper Frank W. Koehler in Lassen County. The three-year-old female, known as BEY03F, was spotted on a trail camera in the mountains north of Santa Clarita.
