On May 19, 1992, Mary Jo Buttafuoco was shot in the head on the front porch of her Long Island home by her husband’s 17-year-old girlfriend, Amy Fisher.

Though Buttafuoco survived, “that was the end of my life as I knew it,” she says of the attack in a trailer for ABC 20/20‘s upcoming special about the dramatic case, which you can watch first on PEOPLE, above.
