"Neal Falls showed up at the woman’s home on July 18 after answering an escort ad... 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....  In Falls’s pocket, police said, was a list of names of potential future victims, all of whom are sex workers who advertised.... Now investigators are trying to determine whether Falls, 45, was responsible for a string of slayings targeting sex workers in Ohio and Nevada, the station reported....  From the moment Falls showed up at the home of his latest alleged victim, a sex worker, he turned violent... 'I knew he was there to kill me,' she said. 'I could tell that he had already done something because he said that he was going to prison for a long time. And that’s when I knew he was gonna kill me.... When he strangled me he just wouldn’t let me get any air... I grabbed my rake and when he laid the gun down to get the rake out of my hands, I shot him. I just grabbed the gun and shot behind me.'"

From "Woman who shot alleged attacker may have slain a serial killer, police say."

He has a gun and he's already strangling you, and you beat him with a rake.
