I signed up for this forum so I could contribute a little to this thread. I hope you do not mind my intrusion. This accident was very close to home for me – literally. I am from Moulton and have a ranch 1-2 miles from the accident.
Oak-Prairie / Post Oak Savannah are a fairly accurate description of the area involved – coastal bermuda pasture with large clumps of oak. It is pretty dry and hot at the moment. Wildlife is pretty varied, but not exceptionally dense. Seeing something interesting is fairly common, but seeing “game” is hit or miss. Knowing the area, wild hogs were most likely the reason for the caliber. They are fairly common, and usually travel in groups (10- 20). Since they are invasive and destructive there is open season, no bag limit. Fwiw they are also quite tasty. I have also walked up on deer and coyotes – not nearly as frequently.
The grandfather is a retired undercover police officer. Local daily paper described the rifle as a “7.62x39 semi-automatic rifle”, the San Antonio news dramatized that by calling it an AK47 assault rifle. It is probably a very decent caliber for hunting hogs in the oak clumps/creek bottoms (but not my personal choice due to the ak/sks safety). The area is very hunting/shooting friendly. I have no doubt the local authorities know the difference between an ak and a sks – and no doubt that the more liberal city news would not care.
I am going to the range tonight for my daughters shooting program. I suspect safety will be strongly emphasized – however that is the rule, not the exception. If I hear any other details I will post back.
