When I was stationed at Ft Hood back in the late 80's, a female soldier walking on the side of road at the base was swept off by flooding waters into a drainage ditch. People driving by witnessed this including my squad leader. Everyone jumped out of their cars to try to help her, but she was gone. They found her body several miles away in a drainage ditch close to the hospital. After that incident, they put up metal bars to prevent a body from entering the drainage pipes, which were quite big. I would hope they still had those metal bars up. Also, while many service members are outstanding people with high morals, you always have those few. I served 11 years in the Army and every base I served at had at least one murder and numerous rapes while I was there. During Reforger one year, I was assigned to guard duty of equipment, two hour shifts on a back road with only one guard at a time. During my 2 to 4 am shift by myself, some scetchy looking servicemember kept driving by slowly practically holding his head out the window to check me out. I called it in that a suspicous driver kept coming by. They sent a patrol out to check on me. Another female on guard duty reported the same incident the next night. During AIT, my room mate was raped walking home from the GI club across the huge PT field at Ft Gordon. He beat her and dragged her into the bushes stuffing her shirt into her mouth to silence her. He only stopped when he seen she was choking on her blood from her nose that he broke and could not breath. My thoughts are someone that likely she new lured her out then abducted her or it was an opportunist rapist/murderer who seen no one was around and she was alone. I would look at people in her company first. They would likely know her personality, if she was naive or likely not one who is going to put up much of a fight. Then check companies next to the armory as well.
