When an 11-year-old girl disappeared from a small town in a remote area of Alaska, investigators wondered if she'd been attacked by a bear or become lost in the dense woods. It turned out neither was true. Her body was discovered 10 days later; she'd been shot twice at close range, and sexually assaulted. A tip from an eyewitness led police to a suspect, and trace evidence found at the crime scene convinced a jury of his guilt.
