Tyler Borys said his wife, 26-year-old Alexandria Cress Borys, was loading groceries into her car at the Kroger in Irmo, South Carolina, when she got into an argument with a woman she didn't know, according to FOX 57 Columbia. After the argument was over, the stranger, later identified by Irmo police as 23-year-old Christina Harrison, allegedly pulled out a gun and shot Borys in the back. The couple's children, a 2-year-old and an infant, were in the car when she was shot.
