Not My Department

I think that you're supposed to call the cops when you hit a deer, but some people don't because they've been drinking or something.  There is usually some damage to the vehicle and, if the driver wants to file an insurance claim, the company will want to see the police report.  Also, if the car goes into the ditch or otherwise becomes undrivable, the tow truck driver is required to call the cops.  Likewise for the ambulance driver, if anybody is injured.  If you want to salvage the deer, you are required to get a permit which, I believe, is free.  I think the DNR as well as the police can issue the permit.  If you are caught transporting the carcass without a permit, you can be charged for illegal possession or something like that.

Disposition of unclaimed deer carcasses is a bit of a problem around here.  The cops, the DNR, or the County Road Commission people will drag it off the road if it constitutes a traffic hazard, but that's as far as they will go.  After that, it's Mother Nature's responsibility, or the property owner, if he cares.  Deer that are hit in the winter usually become buried in snow and are not noticeable until spring. That's when people complain about it, but nobody does anything about it.

I knew a guy, not far from here, who had a deer hit in front of house, which is in the city limits.  The injured deer stumbled into his yard and laid down, but it didn't die.  The guy called the city police, the county sheriff, the state police, the DNR, and the humane society, but none of them would come out.  The guy then called he city police back and asked them if he could shoot the deer in the head to put it out of its misery, but they told him it was illegal to discharge a firearm in the city limits.  After trying unsuccessfully to dispatch the deer with a knife and a hammer, he called the cops again.  They told him it wasn't illegal to shoot a bow and arrow in the city limits and, as luck would have it, archery season was open at the time.  The guy didn't have a bow, but he knew somebody who did and called him up.  The archer came over, shot the deer with his bow, an put his tag on it.  End of story.
