Probably wanted to take the head to a taxidermist.

When I hit one several years ago, I tossed it in the back and took it home, dressed it and kept the rack. No sense in wasting good meat.

If you want weird, poke around the various news archives about Ft Walton Beach Fl. They will occasionally find a decapitated goat laying somewhere around the city. The last one I read about was near the library. As far as I know, they never caught anyone, or had a suspect. This went on for nine years or so. Dunno about recently.
