Idiot shoots girlfriend

Rico says his friend Dave sends this sad story of stupidity:

A Florida man probably wishes he had taken his girlfriend bowling instead of hog hunting, after he accidentally mistook her for a hog and shot her. Steven Egan thought he had just nailed one of the creatures and headed off to locate it. When he heard a rustle, he fired into the woods, thinking it was the fallen animal. Unfortunately, it was his girlfriend, Lisa Simmons, who was collecting oranges that had fallen from the trees. The 52-year-old Egan is a pretty good shot, hitting Simmons with a .30-caliber bullet in both legs. Simmons was airlifted to a nearby hospital, where she remains in serious condition. We think Egan's next hunt may be for a new girlfriend.

Rico says that, besides the obvious error, the idiot committed the worst hunting sin: shooting at something you can't see...
