Wolves or Not?

Montana has a canine mystery on their hands. From the news:

"A mystery predator responsible for 12 sheep deaths in Eastern Montana last month could be connected to the dozens of similar attacks in late 2005 and early 2006, which some officials blame on a domestic hybrid species of wolf.
"Montana’s top wolf official said this week that two suspicious animals remain on the loose in and near Garfield County following the sheep deaths in late August. A third animal killed in a coyote snare earlier this month has yet to be positively identified as wild or domestic."
