**Chris Williamson** (0:00)
Hello, friends, welcome back to the show. My guest today is Dr. Marissa Harrison. She's a psychologist, professor, researcher and an author. All the most infamous serial killers are men, but one in six serial killers are women, a group who have totally slipped under the radar. So who are these women? What are their motives? And why haven't we heard of them? Expect to learn why female serial killers are so neglected in research, what the average demographic of a female serial killer is, who are the most likely victims of a female serial killer, why they kill, the methods they use, and much more. I've been lifting weights for probably about 15 years now, and this year has been the most progress I've made probably since my noob gains. And almost all of that can be laid at the feet of Dr. Mike Isretel and his team at RP Strength. The RP hypertrophy app takes all of the guesswork out of crafting an ideal lifting routine. It's literally spoon fed me a step by step plan for every workout, including the sets, the reps, the weights to use. It automatically adjusts every single week based on progress. It's certainly worked for me. My progress this year has been phenomenal and it's due to nothing else than actually sticking to a science backed evidence based plan. And you can do it too. You can follow the exact same plan that I have. Plus, there are 45 pre-made training programs and more than 250 technique videos.

Why is it particularly interesting to study female serial killers?

**Dr. Marissa Harrison** (3:58)
I think it's interesting because there seems to be this preconceived notions that all serial killers operate the same way. And when we think of a serial killer, we think of, in the United States, at least Ted Bundy or Ed Kemper, we think about monstrous males who commit sex crimes. And female serial killers might be monstrous per some people's definitions, but they tend to be more low key, they tend to poison people, they tend to kill for money and power, versus male serial killers tend to kill for sex. So there are profound sex differences. So I think it's interesting to bring that to public attention.

**Chris Williamson** (4:36)
Right. So you're like a promoter of females, not a promoter, not quite saying that they're good, but just maybe a little bit more attention should be paid. Why have they been so neglected beyond the fact that maybe the way that they kill is less extravagant?
