The commotion started sometime after they lost track of which month the pandemic was in. Leo Guzman and his 24-year-old daughter, Anita, could hear trucks beeping and people working at all hours of the evening in the unmarked warehouses next door to their mobile home in Carson, a suburb 15 miles south of downtown Los Angeles. Thousands of boxes wrapped in plastic were haphazardly pushed to the edges of the lot and stacked in piles as high as 20 feet, one of them leaning like a cardboard interpretation of the Tower of Pisa. Caution tape was strewn around some of the boxes, a blue tarp partly covered others. From where they live, Leo and Anita watched the boxes ascend for many months as the piles became part of their Covid surreality.
