Man charged in snowmobile attack
This year's race was marred by the death of one sled dog in what appeared to be an intentional attack.
Nash, one of the dogs in four-time Iditarod champion Jeff King's team, died after being hit by a man on a snow machine (also called a snowmobile) on the trail early Saturday.
Alaska state troopers arrested Arnold Demoski, 26, of Nulato in connection with that incident and a similar one with another sled team.

in Anchorage spoke with Demoski, who told the Anchorage station that he regretted being out on his snowmobile after a night of drinking.
"I made a mistake, shouldn't have been driving last night," he told the station in a video posted on its Facebook page
. "It wasn't intentional though."
Demoski added, "I just want to say I'm sorry and I feel bad for what I did."
Aliy Zirkle said earlier a snow machine sideswiped her sled as she made her way toward the Nulato checkpoint. Zirkle told authorities a man turned his machine around several times and came back at her before leaving the scene. One of her dogs was bruised, state police said.
Demoski was charged Saturday with two counts of third-degree assault, one count of reckless endangerment, one count of reckless driving and six counts of fifth-degree criminal mischief.
