 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 coworkers. 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, Dad, I've already asked them a couple of times, and they told me, no, they're too expensive.
