Polar bear in fatal Alaska attack was in poor health

ANCHORAGE, Alaska (AP) — A polar bear that killed a young mother and her baby last month in western Alaska was likely an older animal in poor physical condition, but tests came back negative for pathogens that affect the brain and cause aggressive behavior, officials said Monday.

Dr. Kimberlee Beckmen, a state wildlife veterinarian, collected and examined samples from the bear’s head the day after the attack, when weather conditions allowed her and an Alaska State Trooper to fly to the village.

The results of her analysis, which were released Monday but initially were dated Feb. 3, indicate the bear was an adult male, probably older and in poor physical health. Officials sent a tooth to a lab to determine the bear’s age, but those results won’t be known for months.

Standard tests conducted on available tissues for pathogens were negative for rabies, toxoplasmosis, distemper and avian influenza.

“There is no definitive explanation as to why the bear was in poor body condition,” the Alaska Department of Fish and Game and the U.S. Fish and Wildlife Service said in a joint statement.

Summer Myomick and her 1-year-old son, Clyde Ongtowasruk, were mauled to death Jan. 17 as they left the school in Wales, Alaska, for a short walk of about 150 yards (137 meters) to the town’s medical clinic.
