Four years after North Texas home builder Scott Sherman completed a federal prison sentence for mortgage fraud, his new construction materials business received a $600,000 cash infusion. The financial boost came from a blind trust set up to prevent Texas Attorney General Ken Paxton and his wife, state Sen. Angela Paxton, from any overlap in their personal investments and their actions as elected officials. But previously unreleased records from the attorney general's 2023 impeachment investigation show the trust was far from blind and did not shield the Paxtons from its business dealings, including the investment in Sherman's business. Before long, Wildcatter Sand Services and Grayson County Sand and Gravel, which Sherman built with his father, grew into a vast enterprise with various locations and subsidiaries. And along the way, some of those businesses stopped paying taxes to local governments, including school districts.
