What a federal conspiracy charge means — and what the government must prove
A federal conspiracy is an agreement between two or more people to commit a federal crime or to defraud the United States, which you joined knowing its purpose and intending to help it succeed. The crime is the agreement. The plan does not have to succeed, and you do not have to have committed the underlying offense yourself.
The elements, simplified
- An agreement — written, spoken or simply understood — between two or more people.
- A criminal objective: a federal offense, or defrauding the United States.
- You knew the objective and joined the agreement intending to further it.
- Under the general statute, 18 U.S.C. § 371, at least one “overt act” by any member. Several other conspiracy statutes do not require one.
Why prosecutors favor conspiracy charges
- The agreement can be inferred. Emails, texts, payment patterns and timing can be enough; there rarely is a written plan.
- You can be held responsible for others’ crimes. Under the Pinkerton rule, a conspirator can be liable for offenses committed by co-conspirators that were foreseeable and in furtherance of the agreement.
- Others’ words can be used against you. Statements a co-conspirator made during and in furtherance of the conspiracy are admissible against every member.
- Everyone can be tried together, and the statute of limitations can run from the last act of the conspiracy rather than the first.
These rules give the government leverage, but they also have limits. Where the evidence shows a business relationship, association or knowledge — but not an agreement — the charge is vulnerable. Finding those limits in your file is the center of a conspiracy defense.
Federal conspiracy charges we defend in San Diego
The statute charged sets the maximum sentence, so it is one of the first things to understand about your case.
| Statute | What it covers | Maximum prison term |
| 18 U.S.C. § 371 | Conspiracy to commit any federal offense or to defraud the United States — often used in government contracting, bribery, tax, export and securities cases | 5 years |
| 18 U.S.C. § 1349 | Conspiracy to commit mail, wire, bank, health care or securities fraud | Same as the underlying offense (wire fraud: 20 years; 30 if a financial institution is affected) |
| 18 U.S.C. § 1956(h) | Money laundering conspiracy | Same as the underlying laundering offense (20 years) |
| 18 U.S.C. § 286 | Conspiracy to defraud the government through false claims | 10 years |
| 18 U.S.C. § 1962(d) | RICO conspiracy | 20 years (life in limited cases) |
| 21 U.S.C. § 846 | Drug trafficking conspiracy | Same as the underlying offense, including mandatory minimums |
Most of our clients are executives, owners and licensed professionals in health care, defense and government contracting, finance and investments, technology, and import and export. For contractor cases, see our government contractor conspiracy lawyers and our San Diego government contract fraud lawyer pages. For a closer look at specific charges, read our guides to conspiracy to commit wire fraud and conspiracy to defraud the United States. We also defend federal drug trafficking conspiracy charges.
Federal conspiracy prosecutions in San Diego: what recent cases show
The U.S. Attorney’s Office in San Diego regularly charges conspiracy against corporate insiders, executives and professionals, often alongside money laundering, obstruction or perjury counts. Recent public examples:
- Technology executive. A former Qualcomm vice president was convicted at trial of wire fraud conspiracy, wire fraud and money laundering conspiracy and sentenced to 48 months, with more than $100 million in restitution and over $45 million in forfeiture.
- Public-company director. A former director of a Nasdaq-listed company was convicted in September 2026 of conspiracy to commit securities fraud under § 371 — and also of witness tampering, obstruction and perjury tied to how he responded to the investigation. His first trial had ended in a mistrial.
- Defense contracting. In the Naval Information Warfare Center bribery investigation, a former Navy official was sentenced to 72 months in September 2026 for conspiracy to commit bribery; contractor executives were also convicted and sentenced.
- Financial services. The founder of a San Diego financing company pleaded guilty to wire fraud conspiracy, a charge carrying up to 30 years.
- Large networks. In October 2026 the final defendants in a 25-person fraud network pleaded guilty to mail and wire fraud conspiracy and money laundering conspiracy — including people whose role was receiving packages or moving money.
What this means for you: two patterns repeat. First, the response to an investigation can add charges — obstruction, false statements and witness tampering are often easier to prove than the original fraud. Second, the people most exposed are often those who believe their role was too small to matter.
What to do in the first 72 hours of a federal conspiracy investigation
Stop talking about the matter, preserve everything, and get counsel before anyone else involved reaches the prosecutor first. In a conspiracy case, timing among the participants matters more than in almost any other kind of federal case.
- Don’t give an interview. An inaccurate answer to an agent can be a separate felony under 18 U.S.C. § 1001. Agents often already have documents, recordings or a cooperating witness.
- Don’t contact others involved about the investigation. Even an innocent “what do you remember?” call can look like an attempt to align stories — exactly the kind of conduct charged as witness tampering.
- Preserve devices and messages. Deleting texts, WhatsApp or Signal chats after you know of an investigation can be charged as obstruction.
- Assume someone may be cooperating. Many conspiracy cases are built on a participant who agreed to help the government, sometimes by recording calls.
- Learn your status. Target, subject and witness carry very different risks, and status can change.
- Get your own lawyer. Company counsel represents the company, not you.
What happens next depends on what the government has and who is already talking to it. Talk to a conspiracy defense lawyer before you talk to anyone else; finding out where you stand is our first job.

Before charges: target letters, grand jury subpoenas and pre-indictment strategy
Under the Justice Manual, a target is someone the prosecutor or grand jury has substantial evidence linking to a crime and who, in the prosecutor’s judgment, is a putative defendant. A target letter is not an indictment. The period before a charging decision is often the defense’s best opportunity to change the outcome.
What we do at this stage
- Contact the Assistant U.S. Attorney to learn your status and the scope of the investigation
- Respond to grand jury subpoenas for documents and protect privileged material
- Assess whether the evidence shows an agreement, or only a relationship or presence
- Decide whether a meeting, written presentation or proffer would help or hurt — it is never automatic
- Coordinate with counsel for others under a joint defense agreement when that serves you
Proffers deserve particular caution. A proffer agreement protects what you say only in limited ways, and the government can use the information to find other evidence. Talking to a federal conspiracy attorney before the government has your account keeps that decision in your hands.
After an indictment in the Southern District of California
An indictment starts a process, not a verdict. Conspiracy cases are usually multi-defendant and document-heavy, which shapes every stage.
- Initial appearance and arraignment at the federal courthouse on West Broadway, including release conditions.
- Discovery — often hundreds of thousands of pages, plus recordings, wire intercepts and financial records.
- Pretrial motions — severance from co-defendants, suppression, a bill of particulars to pin down what agreement is alleged, and challenges to co-conspirator statements.
- Plea negotiations or trial.
- Sentencing, if there is a conviction.
An experienced federal criminal defense lawyer uses the early months to define the alleged agreement narrowly — because the scope of the agreement drives both guilt and sentencing.
How co-defendants and cooperators change the case
- Co-defendants often plead early and cooperate in exchange for a possible sentence reduction under Sentencing Guidelines § 5K1.1. Their testimony is usually the government’s main proof of an agreement.
- Cross-examining a cooperator about benefits received, earlier statements and inconsistencies is central at trial.
- Whether to cooperate yourself is among the most consequential decisions in the case. It should be made only after you understand the evidence — never in a first meeting with agents.
Penalties and sentencing for federal conspiracy
The statute sets the maximum; the federal Sentencing Guidelines largely drive the actual sentence — especially loss amount and “relevant conduct.”
- Relevant conduct. Under Guidelines § 1B1.3, you can be sentenced for others’ conduct in jointly undertaken activity if it was within the scope of what you agreed to, in furtherance of it, and reasonably foreseeable. Narrowing that scope is often the biggest sentencing issue in a conspiracy case.
- Organizers and leaders receive increases; minor or minimal participants can receive reductions.
- Restitution and forfeiture. Restitution can be ordered jointly with co-defendants. Forfeiture is generally limited to property you personally obtained (Honeycutt v. United States, 2017).
- Organizational fines can reach $500,000 per count or twice the gain or loss, along with debarment, exclusion from federal health programs and licensing consequences.
- Collateral consequences for individuals include professional license action and, for non-citizens, immigration consequences.
A conspiracy defense attorney can often do the most for a client’s sentence by contesting loss figures and the scope of the agreement long before the sentencing hearing.
Defenses to federal conspiracy charges
Every conspiracy defense starts with one question: what, exactly, did you agree to? Prosecutors often prove a relationship and ask the jury to infer an agreement.
- No agreement. Friendship, employment, association or being present is not enough.
- No knowledge of the illegal purpose. You believed the business was legitimate, or followed instructions without knowing of the fraud.
- Buyer–seller relationship. In drug cases, a simple sale is not, by itself, a conspiracy.
- One conspiracy or several. The government may allege one large scheme where the evidence shows separate, smaller ones — which can limit both your exposure and the evidence admitted against you.
- Affirmative steps to abandon the conspiracy can start the limitations clock; the defendant bears the burden of proving it (Smith v. United States, 2013).
- Statute of limitations. Most federal conspiracy charges must be brought within five years.
- Government-agent rule. You cannot conspire only with an undercover agent or informant.
- Entrapment, suppression and evidentiary challenges, including challenges to co-conspirator statements.
Which of these apply depends on the evidence, and they are strongest alongside a clear account of what you actually did. A conspiracy defense lawyer can tell you which ones fit only after reviewing the discovery.
Why a federal criminal defense lawyer with prosecution experience matters in a conspiracy case
Conspiracy cases are won or lost on how the agreement is defined. Former federal prosecutors know how indictments are drafted to stretch that definition, how cooperating witnesses are prepared, and what moves a charging decision.
Many conspiracy pages you will find belong to general criminal firms whose work is mostly state court. Our practice is federal. Our team includes a former Major Frauds prosecutor from the U.S. Attorney’s Office for the Southern District of California, a former deputy chief of a U.S. Attorney’s Office’s criminal and civil divisions, and a defense lawyer with more than 20 years of federal fraud, bribery and obstruction cases. When the alleged conspiracy involves federal contracts, a former federal procurement official joins the team. That is the combination a conspiracy defense lawyer needs when the case turns on what business records really show.

Top San Diego California Federal Sentencing Lawyer
A conviction or a guilty plea is not the end of your case — it is the beginning of the phase that decides how much of your life you spend in federal custody. Federal sentencing is governed by a formula few defendants understand until it is applied to them: the U.S. Sentencing Guidelines, drug quantity and type, criminal history, role in the offense, and any applicable mandatory minimums all interact to produce a recommended range, and prosecutors and probation officers routinely dispute how that range should be calculated.
Watson & Associates’ attorneys, including former federal prosecutors who have stood on both sides of a sentencing hearing, work to identify every legal basis for a reduced guideline range, challenge drug quantity and enhancement calculations before they are finalized, and present mitigating evidence the court is required to consider. If you are facing a federal sentencing hearing anywhere in California, the work that happens before that hearing — not during it — is what shapes the outcome. Call today at 1.866.601.5518 or send San Diego, California federal sentencing lawyer, Carolyn Oliver a message.
Federal conspiracy questions clients ask first
Can I be charged with conspiracy if I never committed the crime?
Yes. Conspiracy is a separate crime from the offense it targets. If prosecutors can prove you knowingly agreed to the plan, you can be convicted even if you never committed the underlying offense and the plan never succeeded.
What does the government have to prove in a federal conspiracy case?
An agreement between two or more people to commit a federal crime or defraud the United States, and that you knowingly and intentionally joined it. Under 18 U.S.C. § 371, it must also prove an overt act by any member. Each element must be proved beyond a reasonable doubt.
Can I be charged with both conspiracy and the underlying crime?
Yes. They are separate offenses, and prosecutors often charge both. A conviction on one does not require a conviction on the other, which is why each count has to be defended on its own terms.
What is the Pinkerton rule?
It is a rule from a 1946 Supreme Court case that makes a conspirator responsible for crimes co-conspirators committed in furtherance of the conspiracy if they were reasonably foreseeable. It is why defining the limits of what you agreed to is so important.
What should I do if I receive a target letter?
Don’t contact the prosecutor or agents yourself, don’t discuss the letter with others involved, and preserve every document and message. Then call a conspiracy defense attorney before the response date. The letter often signals a short window to affect the charging decision.
Someone else in the case is cooperating. What does that mean for me?
It usually means the government has a witness who will describe the alleged agreement, and it may have recordings. It does not mean that witness is accurate. A federal conspiracy attorney will examine what the cooperator received and what they said before.
Can I withdraw from a conspiracy?
Withdrawal requires affirmative steps, such as reporting the scheme to authorities or clearly communicating your departure to the others. It can start the statute of limitations, but the defendant must prove it, and it does not erase earlier involvement.
What is the statute of limitations for federal conspiracy?
Generally five years under 18 U.S.C. § 3282, measured from the last overt act or the end of the conspiracy — not when you first became involved. Some offenses, such as bank fraud, carry longer periods.
Can our company be charged with conspiracy?
Yes. A company can be criminally liable for employees’ conduct within the scope of their jobs. Because the company’s interests and an executive’s interests can diverge, each may need separate counsel early in the investigation.
Should I hire a conspiracy lawyer before I am charged?
Yes, if you have any reason to believe you are under investigation. Pre-charge decisions — whether to speak, what to produce, whether to present information to the prosecutor — often matter more than anything that happens after an indictment.
Is a consultation with Watson & Associates confidential?
Yes. Information you share with a federal conspiracy lawyer while seeking representation is generally protected, even if you do not hire the firm. Tell us what you received and when, and we will tell you what we need next.
