In 2012, Dewayne Anthony Lee Johnson took a job as groundskeeper for a California county school district. “I did everything,” he said in an interview with Time magazine. “Caught skunks, mice, and raccoons, patched holes in walls, worked on irrigation issues.”
He also treated the school grounds with Roundup weed killer, about twenty to thirty times a year and sometimes for several hours a day. On one occasion, the pesticide sprayer broke, drenching Johnson in the herbicide. Afterward, a rash broke out and skin lesions spread across his body.
