Carol found Doug to be suddenly quite controlling. He demanded that she do what he wanted and threatened to abandon her if she did not comply. He wanted a sex slave, someone who would see to all of his needs, mundane and bizarre. She gave in, expecting that in return he would be true to her. But he soon told her that he was tired of having sex with her and needed something new and more exciting. He brought prostitutes home, and to please him Carol went along with it.It was a long hot summer for LAPD. Bodies of young women were found mutilated, even headless, and dumped along the embankments around the freeway ramps.Soon a call came into the station from a woman who implicated her boyfriend in the killings but who refused to offer details that could help to locate him. She could have been just a crank caller, but she was correct about how the murders had been done. She knew details that had not been released to the media. But the switchboard cut her off and she did not call back. If she had, some lives could have been saved and she might not have taken the path she did.It was no crank call.
