Caroline Fraser

Caroline Fraser opens by stating the book's through-line directly: Murderland asks whether the concentration of serial killers in the Pacific Northwest in the 1970s can be connected to the lead pollution that blanketed the region, from smelters and from leaded gasoline. She presents this not as a settled causal claim but as the question that organised years of research, and she is explicit about the order in which the pieces arrived: she knew the serial killers first and learned the lead story later, partly through murders near her home in Santa Fe. That sequencing matters for how the argument is framed — the environmental evidence is brought to a phenomenon she had already been reading about for years.

The entry point is concrete and slightly accidental. Looking at property listings on Vashon Island, she found an advertisement for undeveloped land noting that arsenic remediation might be necessary, and traced the contamination to a lead and copper smelter in Tacoma. From there she discovered a public GIS map that allowed residents to look up arsenic and lead levels in individual yards in Tacoma — including the yard where Ted Bundy grew up. The premise is therefore anchored in a lookup anyone could perform, not in a speculative leap.

Fraser is careful about the scope of the claim. Serial killers are introduced as the most extreme example, while most of the research she cites concerns aggression and juvenile delinquency: longitudinal studies of children exposed to lead, including at low doses, show associations with learning problems, ADHD, delinquency and crime. She also points to places without smelters where leaded gasoline alone produced measurable effects, including IQ decline — a smaller exposure than a large smelter, but widespread enough to matter at population scale.

On leaded gasoline she is blunt: it was a mass exposure experiment conducted on generations of children and adults, and the companies that introduced it — Standard Oil, DuPont and others — were warned by physicians that it would expose the public to more lead than humans had ever had to handle. The motive she gives is narrow and damning: the additive stopped engines from knocking, and the safer alternative, ethanol, could not be patented. Rogan's framing of this as a moral failure is one Fraser accepts and sharpens, extending it to the general pattern of companies knowing a product harms people and selling it for short-term profit.

The Tacoma smelter was owned by Asarco, the American Smelting and Refining Company, controlled by the Guggenheim family — which leads into a digression on institutional reputation, from the Guggenheims' art philanthropy to Rogan's account of the Nobel Prize as an exercise in posthumous image management after a newspaper prematurely reported Alfred Nobel dead and called him a merchant of death. Fraser treats it as the same move: damage done under one name, legitimacy purchased under another.
