 Right. Well, Jack Martin was an experienced plumber, putting in sewer lines behind a shopping center in Houston in 2019. He had repeatedly asked his employer, Best Plumbing LLC, to get trench boxes for him and his co-workers. We spoke with his father, Larry Martin, whom Jack called just days before he was killed in a trench collapse. Two days prior before it happened, he told me, he said, I've already asked them a couple of times, and they told me, no, they're too expensive.
