First off, if it was "far off" your property, did you have permission to be on the property it went on? If not, then I'd suggest getting ahold of whoever owns it to be sure you don't get in a heap of trouble. From what you say, I'm pretty sure you have a muscle hit and you pushed the deer too hard. If you had hit vitals, the deer wouldn't go that far and a gut shot wouldn't give the bright red blood.

You may never recover this deer if it is a muscle hit. Taking low light shots are risky unless you know for a fact you can put the bullet in the right place. Often it is better to hold off for another day.
