He probolly hit a couple of inches below the spine nothing there but ribs... that happened to me a couple of years ago with shot gun...
The ribs are below the spine.
Brandon.....I hate this has happened.....and I can come over tonight if you'd like to help.
I hit a deer in the early part of '07 and I knew I'd hit her a bit "high". I looked all night and into the morning....even took Coop (my Lab) to help. Nothing. I found a deer in the pasture fence a week later.....with this wound in her back. She'd gotten caught in the pasture fence....but everything leads to her being the one I'd hit the week before. I got a pass-thru on that shot....and there was only a smidge of blood at the POI. The arrow felt "greasy".....but no real blood was on it.
Call me if you need me.
