call the GW and get em set up a decoy, easiest, fastest way to catch nigh hunters. If he won't come, call Montgomery.
We caught a couple of poachers one night in Tuscaloosa Co that shot a deer just like you are describing. A 60ish woman and her 80ish mother were up sitting on the porch at 1am when the poachers shot a deer in their yard. The two women jumped in their truck and chased the poachers while talking to Tusc SO on the cell phone. Tusc SO called me and we all arrived at the same spot at the same time...bad timing for the poachers. Those old women were tough as nails....and armed.
