The Latest on the investigation of mountain biker killed by a bear:
Montana wildlife authorities are still trying to determine why a 38-year-old mountain biker was killed by a bear while the biker was riding just outside Glacier National Park. They say the biker likely collided with the bear before he was attacked.
Montana Fish, Wildlife & Parks spokesman Ron Aasheim said Saturday it was a tragic accident and the search for the bear has been called off. Investigators are still trying to determine if it was a black bear or a grizzly, and whether it might have been a female bear trying to protect her cubs.
Brad Treat, who was a law enforcement officer with the U.S. Forest Service, was found dead Wednesday by officers at the scene of the mauling. Treat's riding companion reported the incident and was not attacked.
