I'm not of the "let it lat over night crowd". Busted stomach linings and intestines will make a deer go down pretty quickly as long as it isn't pushed. Once they lay down they will expire if left alone for an hour or 2. The "green slime" tells me lower stomach was opened up. Go to the last place you saw it and start grid searching. Yotes will be on it pretty quickly if you have a lot of them around. I've come up one deer that I had shot less than half an hour with half their rear quarters chewed out!
