In this episode of The Joe Rogan Experience, featuring Joe Rogan and Caroline Fraser, Joe Rogan Experience #2360 - Caroline Fraser explores how Lead Pollution Helped Fuel America’s Golden Age of Serial Killers Caroline Fraser discusses her book *Murderland*, arguing that heavy industrial lead and arsenic pollution—especially from smelters and leaded gasoline—likely contributed to America’s surge in violent crime and serial killers in the 1970s–80s.
How Lead Pollution Helped Fuel America’s Golden Age of Serial Killers
Caroline Fraser discusses her book *Murderland*, arguing that heavy industrial lead and arsenic pollution—especially from smelters and leaded gasoline—likely contributed to America’s surge in violent crime and serial killers in the 1970s–80s.
Using case studies from the Pacific Northwest and El Paso, she connects environmental exposure to neurotoxicity, reduced impulse control, and aggression, while stressing that toxins are one factor among many (trauma, family history, economics).
She highlights specific killers like Ted Bundy, Gary Ridgway, and Richard Ramirez, all raised near major lead sources, and references research showing strong correlations between societal lead levels and violent crime rates over time.
The conversation broadens into corporate malfeasance, regulatory failure, and parallel issues such as plastics, fluoride, and gas stoves, underscoring how profit-driven decisions repeatedly override public health.
Key Takeaways
Lead exposure strongly correlates with violent crime rates across decades.
Economist Rick Nevin’s graphs show that population lead levels (from paint and gasoline) rise and fall almost in lockstep with U. ...

Serial killers often emerged from heavily polluted industrial zones.
Ted Bundy and Gary Ridgway grew up in Tacoma near a major lead/arsenic smelter and highways; Richard Ramirez was raised near ASARCO’s huge smelter in El Paso—suggesting extreme neurological risk layered onto existing psychological and social factors.

Lead and similar metals damage the developing brain—especially in boys.
Long-term studies link even moderate childhood lead exposure to lower IQ, ADHD, delinquency, and impaired frontal cortex development, with MRI evidence that men’s brains show more pronounced structural deficits from exposure than women’s.

Corporate actors repeatedly chose profit over known health risks.
Companies like Standard Oil, DuPont, and ASARCO introduced or maintained toxic products (leaded gas, smelting operations) despite early medical warnings, falsified worker health data, and, in one case, literally calculated that poisoned children were cheaper than shutting down.

Pollution harms poor communities first—but affluent areas are not exempt.
Smelter workers and nearby low‑income neighborhoods got the highest doses, yet places like Mercer Island—an affluent Seattle suburb—still saw bizarre violent incidents among teens, likely influenced by regional lead and highway exhaust exposure.

Cleaning up legacy pollution is technically hard, partial, and often cosmetic.
‘Remediation’ typically means scraping off topsoil, dumping it elsewhere, and capping toxic pits with liners; Tacoma’s smelter site now hosts condos and a park sitting above massive plastic‑lined mounds of contaminated waste that can’t truly be removed.

The same pattern of denial and deflection recurs with new toxins.
From fluoride in drinking water to gas stoves, PFAS, plastics, and DDT, industry and sometimes regulators minimize or bury early warning data, while the public only slowly grasps long‑term neurological and endocrine consequences.

Notable Quotes
“It’s murder. And that’s why I called it *Murderland*.”
— Caroline Fraser
“A little extra lead may have been what pushed some of these guys over the edge.”
— Caroline Fraser
“What else would you call that? If you know that you’re going to kill people but you also are going to make money, and you decide, ‘Let’s do it anyway.’”
— Joe Rogan
“We’ve known since the Romans that lead makes people go crazy, and yet twentieth‑century corporations were telling communities, ‘Oh, arsenic and lead really aren’t a problem.’”
— Caroline Fraser
“As homo sapiens, we’re either gonna get on top of this stuff or it’s gonna get on top of us.”

Thank you for having me.
So I read about the premise of your book online, and immediately I'm like, "I gotta talk to this lady."
(laughs)
"That sounds crazy." Um, please tell people what the premise is, just so we can get started with this.
Yeah, well, I started thinking about this a long time ago, um-
The book's called Murderland.
Yeah, the- the book is Murderland, and, um, I grew up in the Pacific Northwest in the 1970s around the time when there were a lot of, you know, serial killers beginning to pop up. And there always had been this question, why are there so many serial killers in the Pacific Northwest? And so that was the question I was really thinking about, and the- the premise, as it emerged from the research that I did and from some of the facts that I learned about what was happening in the Northwest in this run up to the 1970s is that, um, there may be a connection between, uh, the lead pollution, um, that was prevalent, uh, in the area because of smelters and leaded gas and serial killers. Um, because lead, of course, as we, I think, most people now know has a connection to a heightened aggression and violence in the people who've been exposed to it. So that was, you know, what emerged to me, uh, gradually over the years. I mean, I didn't know a lot about this when I started. Um, I knew about the serial killers, but I didn't really know about the whole lead story, and that came about, you know, I learned about it in part because of some murders. (laughs) I mean, I live in, uh, Santa Fe, New Mexico, which is a lovely place. Um, unfortunately, New Mexico has a high rate of homicides, um, in part it's because it's a poor state, and, uh, doesn't have a big tax base and has, you know, some issues with, uh, drug and alcohol addiction. And few years ago, maybe 2008 or something like that, um, some people, couple of people were murdered down the street from me, and I live in a very peaceful neighborhood, (laughs) you know, very... Um, and that was something that really made me start thinking about, um, the issue of maybe, you know, it might be a good idea to think of moving back to the Pacific Northwest, (laughs) um, uh, which I wanted to do anyway, because I have family up there and... Um, and a few years later, because of that, I was up in the Northwest and looking at real estate ads, and at this point I didn't really know anything about the smelter or the, um, the lead issues. But I was looking at property on Vashon Island, which if you know anything about the Pacific Northwest, is in Puget Sound, it's right across from West Seattle, beautiful little, uh, it was quite rural when I was growing up there, beautiful place. And I came across a real estate ad that said... And this is just for undeveloped property, and it said, "Arsenic remediation may be necessary." And I thought, "Wow, w- what (laughs) , what could possibly have caused so much arsenic pollution on Vashon Island that you would have to get it remediated?" I mean, that just seemed crazy to me. And I was so curious about that, and I looked it up online and, you know, within minutes discovered that there had been, uh, an infamous lead and copper smelter in the City of Tacoma, which is just south of Vashon Island, and so Vashon received a lot of the pollution from that smelter. And so that began a whole process of- of kind of learning about what happened here, you know, what happened in this region. And I also knew, uh, because I'm sort of really interested in serial killers, (laughs) as I mentioned, and had been for- for a long time, reading about them and reading about Ted Bundy and Gary Ridgway, um, and I knew that both Bundy and Gary Ridgway, who was the Green River killer, um, had grown up in Tacoma at the same time that the smelter is... You know, the smelter had been operated- operating there since the 1880s, 1890s, so for a very long time. And I could see that a lot of, uh, news media had been devoted to looking at what had happened in this- in this region, you know? There was a wh- whole map, a GIS map, geographic, you know, information systems that allowed you to look up individual houses...... you know, residential homes in Tacoma and see how much arsenic and lead pollution was in the yards. So I discovered (laughs) that you could actually look up the house where Ted Bundy grew up and see how much lead was in his front yard and his backyard. And the more I read about lead pollution and lead, uh, the association with aggression and violence, the more I wondered, is there a story to be told here about this issue?
