This undated photo shows St. Louis sociology professor Lisa Martino-Taylor. Martino-Taylor performed a study raising new concerns about secret Army testing during the Cold War that sprayed a potentially hazardous chemical into the air in St. Louis. Now, some residents are left to wonder if those tests led to health problems for them and for relatives. (Photo courtesy Lisa Martino-Taylor)
