Timothy Treadwell spent thirteen summers in Katmai National Park and Preserve, Alaska. Over time, he believed he was trusted by the bears, who would allow him to approach them, and sometimes even touch them. Treadwell was repeatedly warned by park officials that his interaction with the bears was unsafe to both him and to the bears. "At best he's misguided," Deb Liggett, superintendent at Katmai and Lake Clark national parks, told the Anchorage Daily News in 2001. "At worst, he's dangerous. If Timothy models unsafe behavior, that ultimately puts bears and other visitors at risk." Treadwell filmed his exploits, and used the films to raise public awareness of the problems faced by bears in North America. In 2003, at the end of his thirteenth visit, he and his girlfriend Amie Huguenard were attacked, killed, and partially eaten by a bear.
