Authorities say Nicholas Hamlett killed a man in Tennessee in an attempt to steal his identity, and reported it to police as a bear attack. He was arrested in South Carolina after a weekslong manhunt.

The 50-year-old had been reported overdue from a deer hunting trip. At least 30,000 brown bears are estimated to be in Alaska and mainly live along the southern coast.

The two backpackers in Canada's Banff National Park seem to have emptied a can of bear spray, trying to get the animal to leave their camp. When rescuers arrived, the bear charged at them.

Authorities received a GPS alert of a bear attack, and once on the scene, found two deceased individuals and an aggressive bear.

The woman's body was found about eight miles outside the town of West Yellowstone, Mont., a gateway community that borders Yellowstone National Park.

The woman sustained non-life threatening injuries and is being treated at a hospital, according to officials. Wildlife officers killed a bear found nearby.
