Emily Heistand claims John Ludwick stalked and harassed her for months before he attempted to kidnap her at knifepoint outside her home this past March. The 23-year-old single mother fought back. Heistand says she got the knife away from Ludwick, then stabbed him multiple times in self-defense.

“He had his arm around my throat and I just started swinging backwards,” she says. “And when I knew that he wasn’t letting go, I just put all my strength into it, and I was like ‘I’m getting away from this.'”

Emily says once she got away from him, she ran into the house and didn’t look back. Ludwick died of his injuries.

“How did you get the knife away from him?” Dr. Phil asks Emily in a daytime exclusive airing Monday.

“I grabbed it by the blade,” she replies, adding, “I didn’t even think. It just happened so fast; I don’t even know.”
