I am not for shooting dogs... many here claim to shoot any loose dog they see... that is a special kind of fuucked up!
What's a special kind of fuucked up is people dumping their dogs out in the country or woods because they are tired of having them.
I bet the investigation turns up some more interesting items. Especially if the parvo infection thing is correct. Never thought about someone basically using pups as a disease delivery system to get rid of wolves, but I guess that would be possible. Not cool purposely letting pups get that disease though. Not cool at all.
