Federal Government Fraud & False Claims Act Defense — District of Massachusetts

When Federal Agents Come Looking: The Investigation Phase

Most federal government fraud cases do not begin with an arrest. They begin with a subpoena, a quiet audit request, a visit from an investigator, or a notice that a former employee has filed a whistleblower complaint. The investigation phase — before any indictment — is where your legal position is won or lost.

Federal agencies tasked with investigating government fraud in Massachusetts include the FBI, the HHS Office of Inspector General, the SBA OIG, the Department of Defense Inspector General, the GSA OIG, and, in complex financial matters, the IRS Criminal Investigation Division. These agencies frequently work jointly and can sustain multi-year investigations. A federal grand jury seated in Boston may already be reviewing documents, interviewing witnesses, or hearing from cooperating individuals connected to your case.

What happens in the first 24 to 72 hours after you learn of federal interest matters enormously. Statements made to federal investigators — even seemingly cooperative, clarifying ones — can become evidence of consciousness of guilt, obstruction, or the underlying offense itself. Under 18 U.S.C. § 1001, making false statements to federal investigators is a separate felony. You do not need to be charged with fraud to be charged with lying about it.

Do not speak with federal agents without counsel present. Do not produce documents in response to informal requests before consulting an attorney. The investigation stage is where the government is still building its case — and it is the stage where a defense lawyer can intervene most effectively.

What the Government Must Prove: The Charges and Their Thresholds

Federal government fraud encompasses a broad cluster of charges. Understanding what the government is actually required to prove — not just what prosecutors allege — is the starting point for any real defense.

Program Fraud and Theft of Government Funds — 18 U.S.C. § 666 and 18 U.S.C. § 641 These statutes cover theft, fraud, and bribery involving federal programs receiving more than $10,000 in federal funds annually. Prosecutors must prove knowing and intentional conduct — negligence, accounting errors, or misunderstandings about program rules are not crimes, even if they resulted in overpayments.

Wire Fraud and Mail Fraud — 18 U.S.C. § 1343 and 18 U.S.C. § 1341 Wire fraud is the government’s most commonly used vehicle for federal fraud prosecutions. It requires proof of a scheme to defraud, use of wire communications (including email and electronic submissions), and specific intent. These charges are often layered on top of program-specific fraud counts and dramatically increase sentencing exposure.

False Claims Act — 31 U.S.C. §§ 3729–3733 The False Claims Act, while primarily civil, carries a criminal counterpart under 18 U.S.C. § 287. Presenting false claims to federal agencies — including Medicare, Medicaid, and federal grant programs — exposes individuals to both civil treble damages and criminal prosecution. The District of Massachusetts has been particularly active in FCA enforcement given the concentration of federal healthcare spending and grant-funded research in the region.

PPP, SBA, and CARES Act Fraud — 18 U.S.C. § 1014 Federal prosecutions for COVID-era program fraud — including Paycheck Protection Program loans, Economic Injury Disaster Loans, and enhanced unemployment benefits — remain active in Massachusetts. The USAO has continued to bring charges in 2025 and 2026 as cases developed through multi-year investigations. These cases often turn on documentation, intent, and the specific representations made in loan or benefit applications.

Grant Fraud and Research Fraud Given Boston’s concentration of federally funded research institutions — Harvard, MIT, Boston University, Northeastern, and major hospital systems — NIH and NSF grant fraud is a distinct enforcement category. The December 2025 Dana-Farber Cancer Institute settlement of $15 million for misrepresented research data in NIH-funded publications put grant recipients across the region on notice. Researchers, principal investigators, and administrators who sign federal grant certifications carry personal legal exposure.

Federal Sentencing: Loss Amount Drives Everything Under the U.S. Sentencing Guidelines § 2B1.1, federal fraud sentences are driven primarily by the “loss amount” — the dollar value the government attributes to the offense. Every additional tier of loss triggers progressively longer advisory sentencing ranges. At $500,000, base sentences begin to exceed two years. At $1.5 million, five years becomes the starting range before any other adjustments. Forfeiture, restitution, and civil penalties compound financial exposure far beyond prison time.

Detention, Release, and the Pretrial Stakes

Federal defendants in Massachusetts are processed through initial appearance before a magistrate judge and may face detention hearings at the Moakley Courthouse in Boston, the Donohue Federal Building in Worcester, or the Springfield courthouse depending on where the charges are brought. Government fraud defendants — particularly those who are professionals, business owners, or executives — are often released on conditions rather than detained, but that is not guaranteed.

Federal prosecutors may seek detention based on risk of flight (particularly in high-loss cases where defendants have assets, travel history, or international ties), obstruction risk (where defendants have access to witnesses or documents), or the weight of the evidence. In government contracting fraud or grant fraud cases, defendants often have business structures, foreign contacts, or institutional affiliations that federal prosecutors use to argue detention risk.

Conditions of release in federal government fraud cases frequently include passport surrender, restrictions on business activities, monitoring of financial transactions, and limits on contact with co-defendants, former employees, or current business partners. For healthcare executives, government contractors, or academic administrators, these conditions can be professionally debilitating even before any conviction. Contesting the scope of pretrial conditions — not just the initial detention determination — is part of the defense work that begins on day one.

The Evidence That Drives Federal Government Fraud Cases

Federal government fraud prosecutions in Massachusetts are document-intensive. Unlike violent crime or drug distribution cases, where physical surveillance and informant testimony dominate, government fraud cases are built on paper — and on the digital record that paper has become.

Electronic Records and Audit Trails Federal investigators subpoena email accounts, accounting software records, billing systems, payroll records, and contract files years before charges are filed. Data from electronic health records, federal contractor databases, and grant management systems is preserved and analyzed by forensic accountants. The prosecution’s case is typically assembled from records that already exist — not from new surveillance.

Cooperating Witnesses and Insider Information In virtually every significant federal government fraud case in Massachusetts, at least one cooperating witness is involved. This may be a former employee, a business partner, a compliance officer, or a co-defendant who has made a deal. The cooperator’s access to internal communications, meetings, and decision-making is often what converts a civil audit into a criminal referral. Identifying who may be cooperating and what they know is among the first tasks of a defense investigation.

Financial Analysis and Loss Calculations The government’s forensic accountants will construct a loss model. That model will almost always overstate actual harm, attribute individual conduct to defendants who were part of institutional systems, and fail to credit legitimate services rendered or proper payments received. Challenging the loss calculation — through independent forensic accounting, restitution negotiations, and evidentiary challenges — directly affects sentencing exposure and can change a case outcome by years of imprisonment.

Grand Jury Evidence Federal grand juries in the District of Massachusetts can compel testimony and document production from anyone with relevant knowledge. Witnesses who appear before a grand jury may not be told they are targets, may be questioned in ways designed to create inconsistencies, and may unknowingly provide testimony that becomes the basis for obstruction charges. If you have received a grand jury subpoena — for testimony or documents — you need counsel before you respond.

Whistleblower Complaints and Qui Tam Actions Under the False Claims Act, former employees and insiders can file sealed qui tam lawsuits on behalf of the government and collect a percentage of any recovery. The government investigates these cases in secret — sometimes for years — before deciding whether to intervene. By the time a qui tam case is unsealed, the government may have already gathered substantial evidence. Receiving notice of an unsealed FCA lawsuit is a warning that a parallel criminal referral may follow.

Defense Strategy in Federal Government Fraud Cases

Federal government fraud defense is not a single strategy — it is a sequence of decisions that begins the moment an attorney is retained and runs through potential trial and sentencing. The cases that end well are usually the ones where defense counsel engaged early.

Pre-Indictment Intervention The most impactful work in federal fraud defense happens before charges are filed. Attorney Stefanie Murphy reviews the contours of the investigation, identifies the likely evidence, assesses the government’s theory of the offense, and — where appropriate — engages directly with the prosecution to present facts and legal arguments that can affect charging decisions. Prosecutors have discretion. Pre-indictment advocacy, voluntary cooperation with defined limits, and presentation of mitigating circumstances can result in declined prosecution, reduced charges, or resolution without a criminal record.

Document and Evidence Review A thorough defense review of the government’s documentary evidence — before the prosecution completes its own analysis — can identify weaknesses in the loss calculation, gaps in the chain of custody, documents that were improperly obtained, and records that affirmatively support the defense. In grant fraud and healthcare billing cases, the difference between criminal intent and administrative error is often embedded in the documentation.

Fourth and Fifth Amendment Challenges Federal investigators often issue broad subpoenas and execute search warrants in government fraud investigations. Overbroad subpoenas can be challenged on specificity grounds. Search warrants obtained on faulty probable cause affidavits are subject to suppression motions. Fifth Amendment protections apply to compelled testimony in all settings — including grand jury appearances and regulatory interviews that precede criminal referrals.

Expert Deployment In cases involving complex billing systems, grant accounting, government contracting requirements, or financial modeling, independent experts are essential. A forensic accountant can challenge the government’s loss model and present an alternative that dramatically reduces sentencing exposure. A regulatory compliance expert can establish that the defendant’s conduct was consistent with applicable program rules — or that the rules themselves were ambiguous enough to negate criminal intent.

Trial Preparation and Negotiated Resolution Not every federal government fraud case should go to trial. But every case must be prepared as if it will. The credible threat of a contested trial — with cross-examination of cooperating witnesses, expert testimony challenging the loss calculation, and jury arguments targeting the intent elements — is what gives defense counsel real leverage in plea negotiations. The resolution that is right for each client depends on the evidence, the exposure, and the collateral consequences that matter most in that person’s professional and personal life.

Collateral Consequence Planning Federal fraud convictions in Massachusetts carry consequences that extend far beyond imprisonment. Healthcare professionals face Medicare and Medicaid exclusion under 42 U.S.C. § 1320a-7. Government contractors and subcontractors face debarment and suspension from federal programs. Licensed professionals — attorneys, accountants, engineers, medical professionals — face licensing board proceedings that can end careers independently of the criminal outcome. Structuring a resolution that accounts for these consequences — not just the prison term — is where experienced federal defense counsel makes a difference.

Experience That Matters in Federal Fraud Defense

Federal government fraud cases require counsel who has worked at the intersection of complex evidence, federal procedure, and high-stakes consequences — not attorneys who handle these cases occasionally alongside state court work.

Attorney Stefanie A. Murphy has represented defendants in serious felony matters where the government’s case was built on institutional evidence, witness cooperation, and prosecutorial resources that dwarfed the defense. She has been identified as lead counsel in high-profile matters reported by the Providence Journal, including a wrongful-conviction DNA case where she challenged forensic evidence and advocated for a defendant held for decades on disputed evidence, and a murder case in which a jury returned a not-guilty verdict despite co-defendants serving life sentences. That kind of trial experience — contesting forensic evidence, managing cooperating witnesses, and preparing for worst-case outcomes — directly informs how federal fraud defense is handled.

Attorney Murphy is admitted to the U.S. District Court for the District of Rhode Island and holds an Avvo Rating of 10.0 and a Martindale-Hubbell Peer Rating of 4.6/5.0. She has co-authored A Practical Guide to Trying DUI Cases in Rhode Island (2nd Edition 2024, MCLE New England) — a publication that reflects the kind of disciplined, evidence-focused legal analysis that complex federal fraud cases demand.

Marin & Murphy represents clients at all three Massachusetts federal court divisions: Boston’s Moakley Courthouse, Worcester’s Donohue Federal Building, and the Springfield U.S. Courthouse. Attorney Stefanie A. Murphy is admitted to the U.S. District Court for the District of Massachusetts (D. Mass. Federal Bar #663646). Matthew T. Marin is admitted in Massachusetts state courts (BBO #672462).
