What to Do If You’ve Been Charged With Conspiracy or Are Under Federal Investigation in Phoenix, AZ

First things first: never speak to law enforcement without an attorney. They are never trying to “clear things up,” or “hear your side of the story.” They are trying to build a case, and anything you say can be used as evidence to convict you.

In many situations, federal conspiracy investigations are underway long before charges are filed. Unlike state cases in Phoenix, AZ, federal investigations may unfold quietly over months or even years, gathering evidence through surveillance, informants, financial records, and electronic communications.

Common signs that you may be under federal investigation include:

Being contacted by federal agents seeking an interview or informal conversation
Receiving a subpoena demanding documents, emails, phone records, or financial information
Law enforcement executing search warrants at homes, offices, or other locations
Learning that others connected to you have been arrested or charged
Being served with a target letter or notified of a federal grand jury proceeding

Even seemingly harmless statements can be portrayed as evidence of participation in a conspiracy. Prosecutors frequently use early statements to form the backbone of federal conspiracy cases.

An experienced federal defense attorney in Phoenix, AZ may be able to:

Step in during the investigation stage before formal charges are brought
Serve as your point of contact with investigators and the U.S. Attorney’s Office
Determine your legal status within the federal investigation
Reduce the risk of self-incrimination during questioning
Begin shaping a defense strategy early in case you are charged
Hire their own experts and investigators and find witnesses to corroborate your defense

Prompt legal guidance in federal conspiracy cases can make the difference between extreme sentencing exposure and protecting your future.

An experienced federal defense attorney in Phoenix, AZ can help you by:

Taking action during the investigation stage before an indictment
Serving as your point of contact with investigators and the U.S. Attorney’s Office
Clarify your legal status as a witness, subject, or target
Help prevent self-incrimination
Developing a defense strategy before formal charges are filed
Hire their own experts and investigators and find witnesses to corroborate your defense

In federal conspiracy cases in Phoenix, AZ, early legal guidance can be the difference between decades behind bars or being able to move on with your life quickly.

When Does a Crime Become a Federal Conspiracy?

Federal conspiracy charges are governed by 18 U.S. Code § 371, which requires prosecutors to establish three essential elements to secure a conviction.

Agreement: Prosecutors must show that at least two people reached an agreement to violate federal law or defraud the U.S. government.
Intent (Mens Rea): The person charged knowingly and voluntarily joins the plan, understanding the goal is to commit a crime.
An Overt Act in Furtherance of the Conspiracy (in most cases): A member of the alleged conspiracy commits an act, even a minimal one, in furtherance of the agreed-upon plan.

Conspiracy is treated as its own federal crime, meaning charges may be filed even if the underlying offense was never carried out.

Importantly, the agreement does not need to be formal or written. It may be inferred from conduct, communications, or circumstantial evidence. As a result, conspiracy charges are among the most powerful and frequently used tools available to federal prosecutors.

A person does not need to:

Directly participate in the commission of the underlying crime
Be aware of every individual involved in the alleged conspiracy
Be involved in every phase of the alleged scheme
Obtain financial gain or other benefits

Even limited or indirect involvement can be portrayed as participation in a conspiracy, particularly when prosecutors argue that actions were “reasonably foreseeable” within the scope of the agreement.

Types of Federal Conspiracy Charges We Defend in Phoenix, AZ

Rather than charging conspiracy alone, federal prosecutors frequently rely on conspiracy allegations to widen responsibility, escalate potential penalties, and pursue complex multi-defendant prosecutions. Combs Waterkotte’s Phoenix, AZ federal conspiracy defense lawyers defend clients facing conspiracy charges across a wide range of federal investigations, including:

Federal drug conspiracy cases brought under 21 U.S.C. § 846, where charges may proceed even if no drugs were seized or personally handled
Mail and wire fraud conspiracy charges under 18 U.S.C. §§ 1343, 1341, commonly supported by emails, financial records, and government interpretations of intent
Financial, banking, and healthcare fraud conspiracy cases that rely heavily on records reviews and prosecutorial interpretations of complex transactions
White-collar conspiracy charges, including tax conspiracy and money laundering conspiracy under 18 U.S.C. § 1956(h)
RICO and enterprise conspiracy under 18 U.S.C. § 1962(d), which can apply without proof that a defendant personally committed racketeering acts
Public corruption and bribery conspiracy under 18 U.S.C. §§ 201 and 666, often relying on circumstantial evidence of intent or agreement
Violent crime conspiracy allegations brought under 18 U.S.C. § 371, § 1959, or related statutes, even when the alleged plan never results in actual violence

Sentencing and Penalties for Federal Conspiracy

Federal conspiracy penalties can be severe and, in many cases, mirror the punishment for the underlying federal offense. Federal law allows courts to impose the same penalties for conspiracy as for the completed offense, regardless of whether the alleged crime was finished.

Under federal law, conspiracy offenses may carry prison sentences of up to five years. Certain federal conspiracy statutes authorize courts to impose the same punishment as the underlying offense, including mandatory minimum prison sentences.

Possible consequences of federal conspiracy convictions in Phoenix, AZ include:

Prison sentences tied to the underlying offense, not merely the conspiracy itself
Mandatory minimum sentencing requirements in drug, firearms, or other offense-specific conspiracies
Court-imposed fines and restitution obligations tied to the alleged conspiracy
Asset forfeiture involving property the government claims is linked to the conspiracy
Post-incarceration supervision ordered by the federal court

The U.S. Sentencing Guidelines play a significant role in federal conspiracy sentencing by evaluating the breadth of the alleged conspiracy rather than isolated conduct. In determining a sentencing range, courts may consider:

How long the alleged conspiracy lasted and its overall scope
The number of participants involved and their roles
Allegations that the defendant acted as a leader or organizer
Conduct committed by co-conspirators that was reasonably foreseeable

As a result, individuals in Phoenix, AZ may face sentencing consequences for acts committed by others — even when their own involvement was limited. Carefully examining and contesting these sentencing considerations is essential in defending federal conspiracy cases.

How Federal Conspiracy Charges Are Defended in Phoenix, AZ

Effective defense against federal conspiracy allegations in Phoenix, AZ requires a detailed analysis of both the evidence and the prosecution’s legal theory. Depending on the circumstances, defenses may include:

Absence of an Agreement
An actual agreement must be shown, and parallel conduct or casual communications do not, by themselves, prove a conspiracy.
Failure to Establish Knowledge or Intent
A defendant cannot conspire to commit a crime they did not knowingly or intentionally agree to participate in.
Presence Alone or Association
Simply being around alleged co-conspirators or having relationships with them is insufficient to prove conspiracy.
Withdrawal as a Defense
Demonstrating withdrawal before further acts occurred may limit or eliminate liability in certain cases.
Insufficient or Unreliable Evidence
Many conspiracy cases rely on cooperating witnesses, informants, wiretaps, or circumstantial evidence that may be challenged for credibility or legality.
Violations of Constitutional Rights
Constitutional violations such as illegal searches, unlawful monitoring, or improper wiretaps may lead to suppression of evidence or dismissal.

An effective federal conspiracy defense in Phoenix, AZ involves aggressive pretrial motions and challenges in addition to trial preparation.
