Musher penalized after killing moose still wins record 6th Iditarod

Dallas Seavey overcame killing a moose and receiving a time penalty to win the Iditarod on Tuesday, a record-breaking sixth championship in the world's most famous sled dog race.

Seavey drove his team a half-block off the Bering Sea ice onto the frozen streets of Nome to cross under the famed burled arch finish line, a triumphant moment in a race marred by the deaths of three sled dogs, including two on Sunday, and serious injury to a fourth.

The deaths prompted one animal rights organization to renew its call for the end of the storied endurance race in which a team of dogs pulls a sled across 1,000 miles of Alaska wilderness.
