According to local officials, Emma was enjoying a sunny afternoon in Cedar Falls with her two young daughters when things suddenly took a terrifying turn. Moments after playing outside near a patch of wild plants, both girls began coughing, wheezing, and showing signs of distress. Their faces reportedly became flushed, their breathing rapid, and their cries filled with panic.

At first, Emma didn’t understand what was happening. But when both children suddenly grew weak at the same time, she realized something was seriously wrong.
