A woman in Charleston, W.Va., may have saved her own life and the lives of many other women, as well, when she shot and killed an alleged attacker in her home last week.

Neal Falls showed up at the woman’s home on July 18 after answering an escort ad she had placed on Backpage.com, according to police. He showed up with a “kill list,” multiple pairs of handcuffs and a Subaru full of weapons and tools, including a shovel, knives, a bulletproof vest, a machete, bleach, trash bags, sledgehammers and axes, according to Fox affiliate KPTV.

In Falls’s pocket, police said, was a list of names of potential future victims, all of whom are sex workers who advertised on Backpage, according to the Daily Dot.
