Arnold Demoski, 26, arrested after crashing into dog-sled team, killing one dog and injuring two during Itidarod Race near Nulato, Alaska

Alaska State Troopers say 26-year-old Arnold Demoski of Nulato is being held on two counts of assault, reckless endangerment, reckless driving and six counts of criminal mischief.

An apologetic Demoski told the Alaska Dispatch News that he had not intentionally driven into the dog teams, but he had blacked out while returning from drinking in another village.

The crashes killed one of King's dogs and injured at least two others 20km outside of Nulato. One of Zirkle's dogs also was injured.

King's team was hit by a snowmobiler, injuring several dogs and killing one — Nash, a 3-year-old male.

Reporter Emily Schwing tells our Newscast unit that King's sled has lights and reflectors.

"It really felt like reckless bravado and playing chicken," King told Emily.
