A Grand Prairie attorney was arrested this week on federal charges alleging he ran a years-long Ponzi scheme built around Texas property tax liens and then tried to obstruct the U.S. Securities and Exchange Commission’s investigation into it with forged documents. The case is a reminder for retirees and near-retirees chasing steady income outside the stock market that an unregistered, informally structured investment, even one pitched by a licensed professional, carries real risk and few built-in protections if the money is never actually invested as promised.
The Alleged Tax-Lien Investment Scheme
According to the U.S. Attorney’s Office for the Northern District of Texas, David Thomas Gilchrist, 70, who has been licensed to practice law in Texas since November 1983, entered partnerships and promissory notes with roughly 20 people who invested with him to purchase property tax liens in Texas counties. Prosecutors say bank records show Gilchrist did not use investor money to buy tax liens as promised, but instead commingled it with other funds, spent some on personal expenses, and used later investor deposits to pay earlier investors, a pattern authorities describe as a classic feature of a Ponzi scheme. Between April 2023 and January 2026, Gilchrist is alleged to have received about $1.45 million from investors while returning only about $789,000. Investigators say he kept the scheme running for years by offering sporadic partial payments and misleading updates, along with implausible excuses for delays that ranged from a government shutdown and an arson investigation to a hurricane-relief deployment; in one instance, while claiming to be hospitalized in Tennessee recovering from surgery, he was allegedly recorded checking into a gym near Mansfield, Texas.

How Prosecutors Say He Tried to Obstruct the SEC
When the SEC opened an investigation and requested documentation, prosecutors allege Gilchrist provided purported quitclaim deeds that turned out to be forgeries, bearing notary stamps and signatures belonging to real Texas notaries who never authorized him to use their credentials. During sworn testimony before the SEC in April and May 2026, prosecutors say Gilchrist claimed he had redacted homeowners’ names on the fraudulent deeds because they were “illegal,” and that he had relied on a woman he barely knew as an intermediary to identify homeowners and deliver cash in Bexar County. The charging documents also allege that days before that testimony, Gilchrist showed up unannounced at the woman’s home, told her husband the FBI was looking for him, and pressured the couple to “take a vacation” to Mexico so investigators could not learn the truth.
Gilchrist faces charges of wire fraud, aggravated identity theft and witness tampering by criminal complaint, and was expected to make his initial appearance before a U.S. magistrate judge shortly after the arrest. In a separate matter, the SEC’s Chicago Regional Office has also filed a civil complaint against him alleging securities fraud. A criminal complaint is merely an allegation of criminal conduct, not evidence, and Gilchrist is presumed innocent unless and until proven guilty in court.
The Potential Penalties If Convicted
Federal sentencing guidelines for the charges Gilchrist faces carry a maximum of up to 20 years in federal prison for each count of wire fraud and each count of witness tampering, along with a mandatory two-year prison term for aggravated identity theft that must run consecutively to any other sentence rather than concurrently with it. “Mr. Gilchrist’s alleged conduct strikes at the heart of investor trust and the integrity of our financial system,” U.S. Attorney Ryan Raybould said in announcing the arrest. SEC Inspector General Kevin Muhlendorf added that attorneys “play a vital role in the SEC’s investor protection mission” and that his office would pursue anyone who tries to obstruct an SEC investigation “through lies, fake documents, or witness tampering.” The SEC Office of Inspector General investigated the case with assistance from the U.S. Marshals Service, and Assistant U.S. Attorneys Alexander Schwab and Douglas Brasher of the Fraud Section are prosecuting it. Any actual sentence would be determined later by a federal judge if there is a conviction, guilty plea or trial verdict.
Verifying an Investment Professional Before Wiring Money
The SEC’s Investor.gov maintains a free search tool that lets anyone check whether a person offering an investment is licensed and registered, which is a basic step that catches a meaningful share of unregistered schemes before money changes hands. Being a licensed attorney or other professional does not substitute for that registration check, since a law license has no bearing on whether an investment vehicle itself is registered or legitimate, and Gilchrist’s decades of standing as a Texas attorney did nothing to protect the roughly 20 people prosecutors say invested with him.
Red Flags in Private, Informal Investment Pitches
Investor.gov’s red-flags checklist lists several warning signs that apply directly to a case like this one: investments structured as private partnerships or promissory notes rather than registered securities, account statements that do not match independently verifiable records, and any difficulty getting money back or a straight answer when a payout is requested. A string of shifting, dramatic excuses for a delayed payment, the kind prosecutors say Gilchrist offered his investors, is itself a red flag worth acting on rather than accepting at face value. Retirees evaluating a pitch built around a niche asset such as tax liens, where few people have direct experience to sanity-check the claims, are advised to get independent, unbiased professional advice and confirm registration status before committing retirement savings, rather than relying on a personal relationship or a professional title as a substitute for verification.
