Authorities in British Columbia say more than one grizzly may have been involved in a bear attack that relatives say left a mother and daughter dead along the province’s central coast. One body was found Monday and the other the next day. Family members of the women reported them missing on Sunday. Efforts to capture the bear or bears involved continue. The attack comes nearly a year after a grizzly attack on a group of 20 elementary school students and teachers in the same area, which left one adult and three children badly hurt.
