Can nutrients affect violent behavior?

To the Editor:

We need to look for more answers when a mass murderer such as the Las Vegas shooter has no known motive for killing.

Dr. William J. Walsh PhD at the Carl Pfeiffer Institute in Naperville, Illinois, demonstrated decades ago that violent criminals often have deranged levels of minerals found on hair analysis. In fact, he could read hair reports and predict with uncanny accuracy who would be violent and who would not.

He designed nutritional programs to normalize the mineral ratios, especially the copper/zinc ratio, and the inmates became less violent. He began this work in the 1970s at Argonne National Laboratories. He conducted research on more than 25 serial killers, including Charles Manson and Richard Speck, and he has assisted the FBI and Scotland Yard.  Some of this research is documented in the following:

“Elevated Copper/Zinc Ratios in Assaultive Young Males,” in Physiology and Behavior, Walsh et al, Vol 62, No. 2, pp 327-329, 1997.

“Reduced Violent Behavior Following Biochemical Therapy,” in Physiology and Behavior, Walsh et al, Vol. 82(2004), pp 835-839, 29 June 2004.

“Micronutrient Therapy for Violent and Aggressive Male Youth,” Walsh et al, Journal of Child and Adolescent Psychopharmacology Vol 10, No. 10, 2017.  Full reports of these studies are available at

He assessed that about five percent of the population had a tendency (perhaps genetic) to form imbalances in these nutrients, and sometimes, violent behavior showed up during childhood or adolescence (torturing pets for example).

He recommended that people be screened with hair analysis, and appropriate nutritional intervention be given for these people. I think this could be a problem with stigmatizing people who do not do the nutritional intervention, labeling them as dangerous, and this brings up the risk of preventive detention.  However, even if the general population were not screened, at least the violent prison population could be screened and treated.

The medical community and criminologists still refuse to act on this evidence because it doesn’t fit into the neat categories of, (1) unethical, immoral, “evil” behavior that needs to be punished, fueled by the belief in and desire for revenge, and (2) insanity, which needs to be treated with drugs or confinement or both. Using these two paradigms to explain violent behavior supports the lucrative prison and pharmaceutical industries, which may explain the reluctance to consider evidence from “outside the box.”  We need to take another look.

To the white supremacists, who propose violent tendencies in African Americans, none of the serial killers or mass murderers were black. All were caucasian, and mostly male, to my knowledge. This also supports the theory of a genetic tendency for deranged biochemistry.
