In the driveway, an unexpected visitor
On a quiet weekday morning in a Bexar County subdivision, a 70-year-old North Texas attorney allegedly appeared without warning at a woman’s home. According to a federal criminal complaint, David Thomas Gilchrist told the woman’s husband that the FBI was looking for him and suggested the couple should consider taking a “vacation” for a couple of years, perhaps to Mexico. The visit came just days before Gilchrist was scheduled to testify under oath before the Securities and Exchange Commission.
Federal prosecutors now allege that this driveway encounter was not an awkward misunderstanding but an act of witness tampering, aimed at pushing a potential witness out of reach of investigators probing what they describe as a $1.45 million Ponzi scheme built on the promise of safe, niche returns from Texas property tax liens.
Gilchrist, a Grand Prairie, Texas attorney, was arrested on August 31, 2026, on a federal criminal complaint. He is charged with wire fraud, aggravated identity theft, and witness tampering, and is expected to make his initial appearance before a U.S. magistrate judge on September 2, 2026.
The charges stem from an investment program that, on paper, looked like a sophisticated way to profit from delinquent property taxes and, in practice, allegedly became a vehicle for forgery, fabricated intermediaries, and a campaign of delay and evasion when investors started asking for their money back.
A tax lien business that never was
The criminal complaint affidavit alleges that between April 2023 and January 2026, Gilchrist solicited roughly twenty investors, often through partnership agreements or promissory notes, for the stated purpose of purchasing property tax liens in several Texas counties. He allegedly told investors he would use their pooled funds to buy tax liens, manage the portfolio, and repay them with attractive interest once delinquent property owners paid up.
Property tax lien investing is, in fact, a real and heavily procedural niche. When a property owner fails to pay local taxes, a county or other taxing authority can sell the lien to private investors, who then earn statutory interest or penalties when the taxes are ultimately paid.
Texas law contains detailed provisions for so-called transferred tax liens, specifying how liens may be assigned, recorded, and enforced. Done properly, the business can be steady, if unspectacular, for specialists who understand the statutes and local practices.
According to investigators, that veneer of legitimacy was central to the pitch. The complaint alleges that bank records do not support Gilchrist’s representations about buying liens. Instead, he allegedly commingled investor funds with other accounts, used money for personal expenditures, and diverted new deposits to repay earlier participants. Prosecutors characterize the pattern as a classic Ponzi structure: newer funds shoring up older promises, with no real underlying investment engine.
In total, the affidavit alleges, Gilchrist collected approximately $1.45 million from investors over the nearly three-year period and returned only about $789,000. The remainder is alleged to have been absorbed into a mix of personal spending and circular payments that kept the program running just long enough to secure additional deposits.
What kept this program out of view for so long is not hard to discern. Private partnerships centered on a niche state-law instrument like Texas tax liens tend to operate far from the retail securities markets that draw the SEC’s routine attention.
Only when the alleged conduct implicated the federal wire fraud and securities fraud statutes did the full weight of federal oversight come into play. A similar operation, structured to avoid securities status and interstate transfers, might have remained a strictly local problem.
Forged deeds and borrowed identities
The alleged misconduct, as described in court filings, did not stop at misrepresentations to investors. Once the SEC opened a formal investigation and requested documentation of the supposed tax lien purchases, Gilchrist allegedly escalated.
According to the complaint, he provided the SEC with a series of quitclaim deeds purporting to show transfers of lien-related interests. On closer review, investigators concluded the deeds were forgeries.
The documents, prosecutors allege, contained notary stamps and signatures belonging to real Texas notaries who had never met Gilchrist and had not notarized the transactions in question. By attaching genuine credentials to fabricated instruments, the filings suggest, Gilchrist allegedly attempted to backfill a paper trail of tax lien activity that did not exist.
Those acts underpin the aggravated identity theft charge, which requires that a defendant knowingly use another person’s identification without lawful authority in connection with certain predicate crimes.
The invented intermediary
The woman whose home Gilchrist allegedly visited in Bexar County plays a different role in the narrative. According to the criminal complaint, she became a central figure not because she helped run a tax lien business, but because Gilchrist allegedly tried to cast her as the face of a fictitious one.
During sworn SEC testimony in April and May 2026, Gilchrist allegedly told investigators he used an undocumented woman in Bexar County as an intermediary to identify delinquent homeowners and deliver cash to them as part of a lien acquisition strategy.
He allegedly claimed he had redacted homeowner names from documents because, in his telling, the homeowners were in the country without legal status. The implication was that the SEC could not safely contact them, and that their identities were too sensitive to share.
The complaint paints a different picture. According to prosecutors, the woman exists but was barely acquainted with Gilchrist and had no role in any tax lien transactions. She was, the filings allege, placed at the center of an invented operation that did not occur as described.
The driveway visit, framed around warnings about the FBI and a suggested multi-year “vacation,” is alleged to have come just days before Gilchrist was due back before the SEC, turning a peripheral acquaintance into an unwitting character in a story he had already told under oath.
Delay, distraction, and the Mansfield gym
While regulators were working through bank records and deeds, investors were asking for their money. The complaint alleges that Gilchrist responded with an evolving series of explanations for why redemptions were delayed or payments had to be rolled over.
Among the reasons prosecutors say he offered: the federal government was shut down, stalling necessary approvals; local authorities were tied up in an arson investigation affecting properties connected to the liens; he had been deployed to assist with hurricane relief. Each explanation, if taken at face value, suggested that external forces, like Washington politics, criminal probes, and natural disasters, were temporarily blocking distribution of otherwise sound investment proceeds.
In one episode highlighted by investigators, Gilchrist allegedly told an investor he was hospitalized in Tennessee recovering from a colectomy. Hospitalization, especially out of state, is a powerful signal that repayment delays are unavoidable and, at least temporarily, excusable.
Yet according to the complaint, during the period he claimed to be recovering in Tennessee, access records showed him checking into a gym in Mansfield, Texas, close to his home base in the Dallas-Fort Worth area. The alleged disconnect between his claimed incapacitation and his actual whereabouts became one more data point in a pattern of shifting stories and eroding credibility.
The Novinger link and a repeat appearance
Gilchrist is not the only name in the government’s paperwork. In a parallel civil action, the SEC’s Chicago Regional Office has filed a complaint charging Gilchrist with securities fraud. That civil case also references Christopher Novinger, a figure already familiar to regulators.
In 2015, the SEC filed a civil complaint, summarized in Litigation Release No. 23256, alleging that Novinger and related parties sold approximately $4.3 million in interests in life-settlement contracts to 26 investors while making material misrepresentations.
The program was promoted on what was billed as a financial radio show, the “Retirement Experts Radio Show,” which the SEC alleged functioned less as neutral advice and more as a marketing platform for the offerings. In 2016, through Release No. 34-78213, the Commission imposed a bar order prohibiting Novinger from associating with broker-dealers or investment advisers.
That bar remained in place when the SEC filed its new civil complaint involving Gilchrist. According to coverage by InvestmentNews on September 1, 2026, the SEC now alleges that Novinger, despite the prior sanction, was steering clients into Gilchrist’s tax lien program. The details of that alleged pipeline are still emerging, but the mere fact that a previously barred financial promoter appears again in a fresh enforcement action underscores longstanding concerns about how effectively sanctions are monitored and enforced in fragmented markets.
The SEC Office of Inspector General is investigating the criminal matter alongside federal prosecutors, with substantial assistance from the U.S. Marshals Service, according to government statements. Assistant U.S. Attorneys Alexander Schwab and Douglas Brasher of the Fraud Section are leading the prosecution, signaling that the case is being treated as more than a routine regional fraud referral.
The gap around the edges
The Gilchrist case, as laid out in the criminal and civil complaints, is not the largest alleged Ponzi operation in recent memory, nor the most complex. What makes it notable is where it sat: at the intersection of a lightly supervised state-law investment niche, informal referral networks, and federal enforcement regimes that tend to activate only after enough red flags accumulate in one place.
The alleged scheme ran from at least April 2023 to January 2026, a span of nearly three years in which paperwork, bank wires, and individual complaints were all, in theory, available to someone with the authority to scrutinize them.
Federal involvement here required wire fraud charges and the invocation of securities laws that treat certain pooled investments as securities even when they are nominally tied to local tax instruments. The question, for regulators and lawmakers, is less why the SEC and Department of Justice eventually acted, and more what kinds of signals could have triggered earlier, narrower interventions.
When barred promoters allegedly reappear as referral sources, when private tax lien partnerships scale into the millions, or when a solo practitioner suddenly claims to be running a multi-county lien portfolio, those data points can be captured long before a driveway conversation turns into an obstruction allegation.
For now, the case moves through the courts. A criminal complaint is only an allegation; it is not evidence, and it is not a conviction. All defendants, including Gilchrist and any individuals named in related filings, are presumed innocent unless and until the government proves its accusations beyond a reasonable doubt in a court of law.
The filings in United States v. Gilchrist and the related SEC actions nonetheless outline a familiar pattern around the edges of the regulatory state, where niche products, personal trust, and delayed scrutiny can combine to give alleged schemes a long runway before anyone in authority is prepared, or positioned, to pull them back to earth.
