Lawrence Martin, Jr., poses for a portrait Tuesday, Sept. 15 2020, at his sister's house in Houston. Martin lost both of his parents to cancer, and his own cancer is in remission. His sister Regina Martin-Morgan is one of dozens of plaintiffs in a wrongful death lawsuit against Union Pacific over legacy rail yard contamination. Last year, Texas health officials identified a cancer cluster in the area near the contamination. "It's a different world when you lose both of your parents," she said. "It's really something that'll take the life out of you."
