Similar experience for me this season, Doe at 15 yards, compound bow, right at dusk, shot, thump. Found the arrow with feces all over it, no sign of blood. Chose not to pursue her, went back the next morning and found her within 30 yards of the treeline she was headed for. Meat was ruined, 60 degree weather overnight. If there had been ANY sign of blood I'd have gone looking for her about 11:00 p.m. (3.5 hours later), but no sign of blood at all. Entry indicated a liver shot, entry blade cuts looked like they might have actually nicked the rib cage. Exit was about 3" back of the ribcage. Good luck... hope it's cold overnight and that you find her quick in the morning!
