The killing of the "most famous wolf in the world" at Yellowstone National Park is coinciding with wildlife officials discussing potential new restrictions for hunting near the park. A collared female alpha wolf known as 832F to researchers and '06 -- for the year she was born -- to fans, was legally killed Thursday in Wyoming outside the park's protected area. She was part of the renowned Lamar Canyon pack. "She was without a doubt the most famous wolf in the world, hands down," Kim Bean, vice president of Wolves of the Rockies, told ABCNews.com. "I watched her since her birth, basically. She was an amazing wolf to watch. She was definitely the most researched in the park. ... She's gone."
