I agree with trapperdave,it sounds as though you made every effort to recover this deer.If you don't hit a vital spot, chances are you won't get them.I have lost 2 different deer that I shot with arrows, both with good pass throughs. Tracked them a long way and they just quit bleeding. The buck I shot last week had been hit by my neihbor and the broadhead was in the top of his shoulder. This deer acted fine and would have been o k if he hadn't come in to my stand. We also butchered one that a friend shot, and found a broadhead with 4 inches of arrow shaft,along side of spine. This deer had been shot by friends dad 2 years previous.
