Campbell is accused of ignoring safety advice, right up to the eve of the collapse. It was the morning of June 5, 2013, when a 4-story, free-standing brick wall came crashing down on top of the Salvation Army Thrift Store on the corner of 22nd and Market Streets. Shoppers and workers inside were buried in the debris -- including one woman, for 13 hours. The grand jury investigation, according to Williams, "places Campbell at the center of culpability." Williams said that instead of opting for the safest way to dismantle the building, Campbell opted for the most profitable way, which included salvaging some of the dismantled parts.
