Wrong place at the wrong time.  Talk about bad luck..  It's not every day you get the opportunity to shoot at a nice trophy buck, so you want to make sure are ready when the opportunity presents itself.  However, this guy's rifle is clearly not sited in and the poor rabbit is sent flying:

To be fair, the hunter deserves some credit as he explains what went wrong.

To make a long story short, my son dropped my rifle one week before this hunt and did not tell me it was dropped, after making two repetitive shots with custom loads, I knew it was not me. 15 minutes later, buck came back out and I had a chance to get my other gun from my truck and harvest him, however I did not film the fatal shot, but I have pictures. Please notice innocent bystander (rabbit) on the first shot. I was shooting a 7mm Magnum.

Moral of the story is to always check your firearm after letting anyone borrow it.
