This series of columns examines the damage caused by repeated abuses of Texas adverse possession laws by companies headed by Douglas T. "Chase" Fonteno. The series outlines the complex nature of Fonteno's interlocking businesses and the web of deceit that helped hide his real estate transactions from county, state and federal agencies. He claimed deeds to other people's houses, without the real owners' knowledge or consent, and sold those houses to unsuspecting people who, in almost all cases, were poor, uneducated and often spoke little English. The series uncovered millions of dollars in unpaid taxes and liens, along with other nefarious activities that appear to have included document forgery and misuse of a Texas notary stamp. Fonteno's antics helped delay urban development in one of Dallas's most downtrodden urban neighborhoods.
