  1. They got cameras watching you pump gas but if you get shot to death in the parking lot, you’re on your own

  2. Looking at Mr. Day’s record something tells me he brought this on himself… doubt the detectives are burning the midnight oil on this one. I sure wouldn’t. All around sad situation 🙁

    1. Y’all are some in sensitive mfkers in this county…what the hell does his record have to do with anything?? That’s the first thing y’all Google…all you needed to say was NOTHING!!! Better yet post your RECORD!!

      1. well, if you surround yourself with feral animals, you’re bound to get bit and mauled eventually… Thats what his record might reflect. I didnt look at it nor do I care.
