That stinksI hate that for you, but you did the right thing by sneaking out for the night. My brother shot a doe 2 years ago in the chest and we tracked her for about 3 or 4 miles and never found her. We didnt have the liberty of letting her lay overnight due to the high temps and she would have spoiled but she did have about 5 or 6 hrs to lay and die, if he didnt go far then he should be dead close to where you last heard him, if you got lucky and hit the heart or a lung. good luck and hope you find him.
