New Book Links Toxic Air, Industrial Pollution with Serial Killers
A new book looks at why there were so many serial killers in the Pacific Northwest in the 1970s and 80s.
The author thinks that being exposed to poisonous stuff in the air and water, like lead, might have hurt kids' brains, making them more likely to become violent.
She also talks about how the media made serial killers seem cool when they weren't.
She says that now that we're better at taking care of kids and have cleaned up the environment, there are fewer serial killers.
The book explains that we may have made healthier humans.
New book explores potential link between environmental toxins and serial killer activity in the Pacific Northwest.
Author Caroline Fraser proposes the "lead-crime hypothesis," linking exposure to toxic metals to altered brain development.
Fraser's research focuses on lead and arsenic exposure from industrial pollution in cities like Tacoma, Washington.
The book cites a correlation between rising lead levels and violent crime, with a decrease in both following lead's phase-out.
Fraser challenges the romanticized image of serial killers, emphasizing their cognitive and emotional impairments.
