I would tend to doubt that law enforcement is making much of a special effort to find this guy...who wants to actively hunt for a mtn man that has a scope high powered rifle and likely knows how to shoot it.
He’ll mess up eventually on his own.
Snow on the ground should make for some easy tracking.
Over fights by air craft ect. I coulds see that in non snow months that he be hard to fine.
After he kills some one then they will spend millions hunting him down.
