U.S. Government Admits To Spraying A Black Neighborhood In St. Louis

In the 1950s and 60s, the Army secretly sprayed a mysterious fog over Pruitt-Igoe, a predominantly Black housing project in St. Louis. Residents, including children, remember playing in the thick, foul-smelling smoke, not knowing they were being used as human guinea pigs.

The government has now admitted the fog contained zinc cadmium sulfide, a known carcinogen, as part of a Cold War experiment to see how a biological attack might spread. Decades later, former residents are dying from rare forms of cancer, and they believe the government is still covering up the full extent of the experiment, possibly including radioactive materials. Families now demand answers, compensation, and the truth.
