The Orange County–connected laboratory owner was wanted for nearly four years, but federal authorities have not yet confirmed her extradition to the United States
The FBI announced on September 14, 2026, that Emylee Thai, an Orange County and Houston laboratory owner accused of participating in a massive Medicare genetic-testing and kickback scheme, had been captured in Vietnam.
Thai had been a fugitive since December 2022, when federal investigators say she removed her court-ordered GPS monitoring device and fled the United States aboard a private aircraft while using a false identity.
She was later placed on the FBI’s Most Wanted Fraudsters list, with a reward of up to $150,000 offered for information leading to her arrest and conviction.
Her capture is a significant development in a federal case involving approximately $142 million in Medicare claims. However, the case is still developing, and several important questions remain unanswered.
Has Thai been extradited to the United States?
Not according to the official information available as of September 16, 2026.
The FBI confirmed that Thai was captured in Vietnam with help from international law-enforcement partners. However, the agency did not say that she had been extradited, deported, transported back to the United States, or brought before a federal judge.
Capture and extradition are separate legal events. A person arrested abroad may remain in foreign custody while an extradition request is considered. A fugitive could also be deported for an immigration violation, expelled through another arrangement, or voluntarily returned.
Until the Department of Justice confirms Thai’s arrival or a new court appearance appears on the federal docket, the most accurate description is:
Emylee Thai has been captured in Vietnam and is wanted in the United States to face pending federal charges.
Reports stating that she has already been extradited appear to go beyond what federal authorities have publicly confirmed.
Medicare—not Medicaid
Another clarification concerns the government program allegedly defrauded.
In announcing Thai’s capture, FBI Director Kash Patel referred to more than $100 million in “Medicaid fraud.” However, the federal indictments, FBI wanted notice, and Department of Justice case summary identify the affected program as Medicare.
The federal court documents allege that approximately $142 million was billed to Medicare and approximately $95 million was paid.
The $142 million figure represents the amount allegedly billed—not the amount proven stolen or personally received by Thai.
Who is Emylee Thai?
According to the indictments, Thai was a resident of both Orange County, California, and Harris County, Texas.
She allegedly owned or controlled several clinical laboratories:
- ApolloMDx LLC, based in Harris County, Texas
- Artemis DNA TX LLC, the later name of ApolloMDx
- Artemis DNA CA LLC, based in Orange County, California
ApolloMDx was enrolled in Medicare as an independent clinical laboratory. Thai allegedly signed Medicare provider-enrollment documents on behalf of the laboratory and certified that she and the company would comply with Medicare regulations and the federal Anti-Kickback Statute.
Prosecutors allege that, between approximately December 2019 and May 2022, Thai and others used the laboratory to bill Medicare for genetic tests that were frequently medically unnecessary, obtained through illegal kickbacks, supported by altered documentation, or otherwise ineligible for reimbursement.
These remain government allegations. Thai is presumed innocent unless the prosecution proves her guilt beyond a reasonable doubt.
How did the alleged scheme operate?
The alleged operation involved laboratories, outside marketers, Medicare beneficiaries’ DNA samples, doctors’ orders, questionable diagnoses, altered dates of service, and payments allegedly tied to Medicare reimbursements.
Marketers allegedly supplied DNA samples and doctors’ orders
According to the indictments, outside marketers sent ApolloMDx Medicare beneficiaries’ DNA samples and signed doctors’ orders for genetic testing.
The samples and orders gave ApolloMDx the documentation needed to submit claims to Medicare.
The court documents do not explain how every beneficiary was recruited. In similar genetic-testing schemes, federal authorities say older adults have been approached through unsolicited telephone calls, health fairs, community events, door-to-door visits, mailed cheek-swab kits, online advertisements, and offers of “free” cancer or heart-disease testing.
Marketers allegedly received kickbacks
Prosecutors allege that Thai paid marketers in exchange for sending DNA samples and doctors’ orders to ApolloMDx.
The original indictment alleges that Thai agreed to pay one marketer 35% of the money Medicare reimbursed ApolloMDx for that marketer’s referrals.
Thai also allegedly offered a bonus if the marketer and associated sales representatives generated more than 1,000 DNA samples.
The superseding indictment alleges that another marketer, Lily Tran Daniel, received compensation based on 15% of Medicare reimbursements.
Federal law generally prohibits paying or receiving compensation to induce referrals for medical services covered by Medicare or another federal health-care program.
According to prosecutors, payments were disguised as legitimate “salary,” “fixed pay,” “flat fee,” or marketing compensation.
Diagnoses allegedly were altered
The government alleges that Thai, Daniel, and others altered or fabricated doctors’ orders to include diagnoses that made beneficiaries appear eligible for genetic testing.
Medicare does not cover every genetic test for every beneficiary. The test generally must be reasonable and necessary for the patient’s medical condition and ordered by a treating physician who will use the results in managing the patient’s care.
Prosecutors allege that some ApolloMDx tests did not meet those requirements.
Dates of service allegedly were changed
The superseding indictment also alleges that orders were altered to make it appear that DNA samples had been collected on different dates when they had actually been collected on the same day.
This allegedly allowed ApolloMDx to submit claims covering multiple dates of service for the same beneficiary.
Medicare allegedly paid approximately $95 million
The government alleges that ApolloMDx submitted approximately $142 million in claims between December 2019 and May 2022.
Medicare allegedly paid approximately $95 million.
The original indictment includes an example in which Medicare was reportedly reimbursing ApolloMDx approximately $8,295.72 for each cardiovascular genetic test. Prosecutors allege that Thai shared this reimbursement information with a marketer to encourage additional referrals.
Proceeds allegedly funded kickbacks and personal benefits
The superseding indictment alleges that proceeds were transferred to Thai, marketers, and other alleged co-conspirators.
Among the payments described by prosecutors:
- Approximately $11.7 million allegedly went to companies controlled by Lily Tran Daniel.
- Approximately $630,000 allegedly went to a company controlled by Kenneth Reynolds.
- Payments of approximately $396,000 and $310,000 allegedly went to companies associated with other marketers.
Texas authorities also reported that law-enforcement officers seized sports cars, a sailboat, and three properties valued at approximately $7.1 million.
The seizure of property does not establish guilt. The government must still prove that the assets are connected to criminal proceeds and legally subject to forfeiture.
Were other people charged?
Yes. The federal documents describe a larger operation involving several named defendants and additional unnamed marketers.
Lily Tran Daniel
Daniel, identified in some Justice Department documents as Lily Tran Daniels, was an Orange County resident accused of referring DNA samples and signed doctors’ orders to ApolloMDx.
She was charged with conspiracy to commit health-care fraud, conspiracy to defraud the United States and pay or receive health-care kickbacks, and receiving health-care kickbacks.
Prosecutors allege that companies under her control received approximately $11.7 million in referral-related payments.
Kenneth Reynolds
Kenneth Reynolds of New Castle County, Delaware, allegedly owned Snuggie & Snuggie LLC and referred DNA samples and doctors’ orders to ApolloMDx.
He was charged with conspiracy to defraud the United States and pay or receive health-care kickbacks, along with receiving health-care kickbacks.
Approximately $630,000 allegedly was paid to his company.
Lillian Diem Thai
Lillian Diem Thai was charged in a separate 2023 case with destruction or alteration of records in a federal investigation.
Court records show that she was arrested at Los Angeles International Airport on June 28, 2023, after returning on a flight from Vietnam. A federal magistrate judge ordered her detained while the case proceeded.
The available public documents do not establish that Lillian Thai had the same alleged role in the genetic-testing and kickback operation. Her charge concerned allegedly altered or destroyed records connected to the investigation.
Additional unnamed participants
The indictments also refer to “Marketer 1,” “Marketer 2,” and other known or unknown alleged co-conspirators.
The public documents reviewed for this article do not identify all of them. They should not automatically be assumed guilty or publicly identified through speculation.
How did Thai become a fugitive?
It is technically the federal court—not the FBI—that issues an arrest warrant. The FBI investigates and makes arrests under the warrant’s authority.
| Date | Development |
| July 11–12, 2022 | Thai was charged with health-care fraud and kickback conspiracies and paying kickbacks. The indictment was filed on July 12. |
| Later in 2022 | Thai was arrested and released on bond, subject to GPS monitoring and other conditions. |
| December 8, 2022 | Authorities say her monitor was removed. Her last publicly identified U.S. location was Harry Reid International Airport in Las Vegas. |
| December 9, 2022 | A federal court issued an arrest warrant after Thai was charged with tampering with the GPS device. |
| 2023 | Investigators determined that Thai allegedly left the country aboard a private aircraft while using a false identity. |
| June 21, 2023 | A superseding indictment added Lily Tran Daniel and Kenneth Reynolds to the health-care fraud case. |
| July 5, 2023 | Thai was separately indicted for destruction and alteration of records in a federal investigation. |
| July 6, 2023 | A second federal arrest warrant was issued. |
| June 23, 2026 | Thai was added to the FBI’s Most Wanted Fraudsters list, with a reward of up to $150,000. |
| September 14, 2026 | The FBI announced her capture in Vietnam. |
| September 16, 2026 | Federal authorities had not publicly confirmed her extradition, arrival in the United States, or post-capture court appearance. |
What happens next?
The Department of Justice must clarify whether Thai will be extradited or returned through another legal procedure.
Once she is in U.S. custody, the court will address her detention, legal representation, discovery, motions, scheduling, and eventually a plea or trial unless the charges are resolved through another lawful process.
The government must prove every charge beyond a reasonable doubt. Thai has the right to challenge the alleged dollar amounts, the government’s interpretation of the transactions, whether particular tests were medically necessary, and whether she knowingly participated in criminal conduct.
No public statement from Thai or her attorneys responding to the latest capture announcement was located in the official materials reviewed for this developing story.
