A grizzly bear pulled a woman from her tent in a small Montana town in the middle of the night and killed her before fellow campers could use bear spray to force the bruin out of the area, wildlife officials said. Leah Davis Lokan, 65, of Chico, California, was on a long-distance bicycling trip and had stopped in the western Montana town of Ovando when she was killed early Tuesday, said Montana Fish, Wildlife and Parks officials as they provided more details about the attack. Lokan was killed on the bear's second visit to the site where she and two fellow bicyclists were camping near the post office, officials said. The approximately 400-pound (181-kilogram) grizzly first awakened the campers about 3 a.m., officials said. They took food out of their tents, secured it and went back to sleep, they said.
