Los Angeles Federal Criminal Defense Attorney: Robert M. Helfend

If you have been contacted by federal agents, served with a target letter, or indicted in the Central District of California, you have a narrow window to take the right steps. Robert M. Helfend is a Los Angeles federal criminal defense attorney who has defended federal cases since 1984. He has handled more than 4,000 state and federal criminal cases, and provides direct attorney involvement in the defense.

Robert is admitted to the U.S. District Courts for the Central, Northern, and Southern Districts of California. His Super Lawyers profile lists selection for 2020–2023. The firm also reports recognition from the National Trial Lawyers Top 100.

Early advice helps you address interviews, court notices, and evidence preservation. Federal cases follow federal procedure and may involve a different courthouse, prosecutor, and sentencing framework from a California state prosecution.

A federal accusation is not a conviction. The prosecution must prove each element beyond a reasonable doubt at trial. Preparation may begin before an indictment and can include reviewing the government’s evidence, evaluating suppression issues, addressing the Sentencing Guidelines, and considering available plea terms. The appropriate approach depends on the facts and the client’s objectives.

The Helfend Law Group represents clients facing federal criminal charges across the Western Division courthouses in downtown Los Angeles, the Eastern Division in Riverside, and the Southern Division in Santa Ana.

Federal case results

Federal charges do not always end in conviction. In a firm-reported federal cocaine conspiracy case involving 12 kilograms, Helfend’s analysis of the government’s evidence and use of expert witnesses persuaded the U.S. Attorney’s Office to dismiss the client’s case before trial. The source does not identify a Fourth Amendment search challenge as the basis for that dismissal. In a separate wire fraud and bank fraud trial, the firm reports that seven counts were dropped after Helfend questioned an FBI agent about missing evidence and obtained important admissions. The client was convicted on the remaining three counts.

More outcomes are listed on the recent case results page.

“Mr. Helfend absolutely saved my bacon. After finding myself charged with fraud, I was terrified. I have never been introduced to the legal system from this side before, and it was unsettling. However, Robert was able to calm me down and help me figure out my situation. He even got the case dropped before trial!”

What counts as a federal crime?

A federal crime is any offense that violates federal law, usually codified in Title 18 of the United States Code. Conduct becomes federal in three main ways.

The conduct crosses state lines, like wire fraud or interstate drug distribution. The conduct involves a federal interest, like mail fraud, tax evasion, or fraud against a federal healthcare program. Or the conduct happens on federal property, including military bases, national parks, and federal buildings.

Some conduct can be charged in either federal court or under California law in state court. Drug crimes, firearms offenses, and certain fraud schemes often qualify under both. Federal prosecutors generally pick up the matter when the conduct is large enough or organized enough to justify federal court attention.

Common federal crimes the firm defends include wire fraud, mail fraud, bank fraud, securities fraud, healthcare fraud, money laundering, drug trafficking, identity theft, federal firearms charges, child pornography offenses, racketeering and RICO, tax fraud, public corruption, and obstruction of justice. These criminal offenses are prosecuted by the United States Attorney’s Office, and a single federal offense often arrives with related counts stacked on top.

What does a federal criminal defense attorney do?

A federal criminal defense attorney represents people who are under investigation or facing federal criminal charges in the federal court system, from the first contact with agents through trial, sentencing, and appeal. The job covers pre-indictment negotiation with federal prosecutors, discovery review, suppression and dismissal motions, Sentencing Guidelines strategy, plea negotiation, and trial.

The earlier that work starts, the more options stay open. Before charges are filed, a defense attorney can engage the United States Attorney’s Office directly, present facts the agents missed, and sometimes keep the case from being charged at all. After indictment, the focus turns to attacking the government’s case and building a comprehensive defense around the specific elements the prosecution has to prove.

The federal government brings near-unlimited resources to a criminal prosecution, so a matching level of preparation on the defense side is not optional. Some federal crime lawyers concentrate on one charge type; others handle the full range of federal criminal law, from white collar cases to drug conspiracies. The right fit is an attorney who has done the specific work the case requires, in federal court, recently.

Why federal cases are different from state cases

People who hire a criminal defense attorney with no federal court experience usually find out the difference too late. Federal court runs by its own rulebook, and the federal laws that govern a federal crime case differ in important ways from California law and the state court system.

The investigations are longer and quieter. Federal agencies like the Federal Bureau of Investigation, the Drug Enforcement Administration, the Internal Revenue Service Criminal Investigation Division, the ATF, the Secret Service, the U.S. Postal Inspection Service, and Homeland Security Investigations build federal criminal cases over months or years before charges are filed. By the time the federal government files charges, the prosecution’s case is already largely built.

The discovery rules are stricter. Federal Rule of Criminal Procedure 16 governs discovery, supplemented by the Jencks Act and Brady and Giglio obligations. Missing a deadline can foreclose a defense argument permanently.

The sentencing system is its own discipline. Federal sentences are calculated using the Federal Sentencing Guidelines, which combine an offense level with a criminal history category to produce a recommended range. Prior convictions count against you in the criminal history calculation. After the United States Supreme Court’s decision in United States v. Booker, the Guidelines are advisory rather than mandatory, but federal judges must still calculate them correctly. Mandatory minimums set by statute also constrain what a judge can do, particularly in drug cases and child pornography cases.

Trial and negotiated resolutions require different preparation. Counsel should assess the government’s evidence, available motions, plea terms, and sentencing exposure. If the case proceeds to trial, the prosecution must prove every element beyond a reasonable doubt. A negotiated resolution should be evaluated against the evidence and consequences of the alternatives.

Federal custody has its own credit rules. There is generally no parole for modern federal offenses. Good-conduct credit and, for eligible prisoners, First Step Act time credits can affect custody or prerelease placement. Eligibility, disciplinary history, the offense, and sentence computation matter; a fixed percentage is not a reliable prediction for every client.

Your legal rights during a federal investigation

Federal investigations begin in different ways. Sometimes federal agents knock on your door. Sometimes you receive a target letter from the U.S. Attorney’s Office. Sometimes the first notice is a federal search warrant or an arrest warrant served at dawn.

Whatever the trigger, your legal rights stay the same.

You have the right to remain silent under the Fifth Amendment. Federal agents are trained to make conversations feel casual and helpful. They are not. Anything you say can become evidence against you. Lying to a federal agent is its own felony under 18 U.S.C. § 1001, even if you’re never charged with the offense being investigated. If agents ask for an interview, the safest answer is that you are willing to talk, but only after speaking with your attorney. That is your constitutional right, and it protects you from the consequences of misspeaking or misremembering a fact during an interview with federal investigators.

You have the right to legal counsel. You can refuse to answer questions until your attorney is present.

You have rights under the Fourth Amendment when the government is gathering evidence. Search warrants that are overbroad, based on stale information, or supported by false statements in the affidavit are all subject to challenge, and so are searches that exceed the warrant’s scope. An illegal search can result in suppression of every piece of evidence the government seized, which sometimes ends a criminal prosecution before it begins.

A target letter is written notice from a federal prosecutor or the Department of Justice that you are the target of a grand jury investigation. It usually describes the federal crime being investigated and what prosecutors expect next, typically testimony or a meeting. A target letter is not an indictment, but it often means charges are close, and it is the point where retaining legal counsel stops being optional.

The legal process moves quickly once federal criminal charges are filed, and your decisions in the first hours and days have outsized weight. The single best step is calling a federal criminal lawyer before you do anything else.

The federal criminal process in Los Angeles

Most federal cases follow the same general path, though every case has wrinkles that change strategy.

Investigation. Federal agents may approach you. You may receive a target letter or grand jury subpoena. Investigators may search your home, business, or phone under warrant. Two rules apply: do not answer questions without legal representation, and do not destroy or alter any document, file, message, or device. Doing so is obstruction under 18 U.S.C. §§ 1512 and 1519.

Indictment. If the grand jury finds probable cause, it returns an indictment. Indictments in this district are filed at the First Street U.S. Courthouse at 350 W. 1st Street in downtown Los Angeles. The federal courthouse there houses the active U.S. District Judges, while the Edward R. Roybal Federal Building two blocks away houses most magistrate judges and handles initial appearances.

Some federal cases proceed by criminal complaint and arrest before indictment, particularly when agents believe a defendant is a flight risk. An indictment must then follow within 30 days under the Speedy Trial Act.

Initial appearance and detention. Federal Rule of Criminal Procedure 5 requires an arrested defendant to be brought before a judicial officer without unnecessary delay. Release or detention is addressed under the Bail Reform Act. Counsel can present information relevant to release conditions and respond to a detention request.

Arraignment and motion practice. At arraignment, you enter a plea. The court sets a trial date and a motion deadline. Pretrial motions are where most defense work happens. A successful suppression motion can end a case before trial. A successful Franks motion, where the defense shows that an officer made false or reckless statements in a search warrant affidavit, can result in evidence being thrown out and the case dismissed.

Plea negotiations. Most federal criminal cases resolve through plea agreements. The government’s offer is usually shaped by the Guidelines calculation the prosecutor expects the court to adopt. Defense work focuses on reducing the offense level, contesting enhancements, securing acceptance of responsibility credit, arguing for a 5K1.1 substantial assistance departure where cooperation is involved, and negotiating around mandatory minimums.

Trial. Federal trials are governed by the Federal Rules of Criminal Procedure and Federal Rules of Evidence. The pace is faster and the rules stricter than what’s typical in state court. The government must prove every element of every charge beyond a reasonable doubt.

Sentencing. The court schedules sentencing after a guilty plea or verdict. The probation office generally prepares a presentence investigation report, and the parties can raise objections and submit sentencing arguments. The judge calculates the advisory Guidelines range, considers the factors in 18 U.S.C. § 3553(a), and applies any controlling statutory minimum or maximum.

Appeal. Federal appeals go to the U.S. Court of Appeals for the Ninth Circuit. The notice of appeal must be filed within 14 days of judgment.

Common defense strategies in federal criminal cases

Every case is different, but the playbook draws from the same set of moves.

Pre-indictment intervention. When the firm gets involved before charges are filed, the goal is to keep the case from being charged at all, or to narrow what the government decides to charge. This means engaging directly with the AUSA, presenting facts the agents may have missed, and where appropriate, presenting the client to the U.S. Attorney’s Office on the defense’s terms.

Challenging the search. Many federal cases turn on what was found during a search. If the warrant was overbroad, if the affidavit contained false statements, if the agents exceeded the warrant’s scope, or if the search itself violated the Fourth Amendment, the government’s evidence may be suppressed.

Challenging the charge and the evidence. Federal prosecutors must prove each element beyond a reasonable doubt at trial. Rule 12 permits certain legal and procedural objections before trial, but a pretrial motion generally does not decide the disputed facts bearing on guilt. Evidence gaps can also inform defense negotiations and the government’s decision whether to proceed.

Challenging the Guidelines calculation. Even when guilt is not seriously contested, the advisory Guidelines range is an important part of sentencing. Loss amount in fraud cases, drug quantity in narcotics cases, role enhancements, and obstruction enhancements can each move the sentencing range by years. Litigating these at the presentence stage is where the actual time gets shaved.

Federal sentencing exposure on common charges

Federal crimes carry statutory maximums and, in some cases, mandatory minimums set by Congress. The Guidelines range a defendant actually faces depends on the specific offense conduct, criminal history, and adjustments.

Offense	Statute	Statutory maximum	Mandatory minimum
Wire fraud	18 U.S.C. § 1343	20 years (30 if a financial institution is involved)	None
Mail fraud	18 U.S.C. § 1341	20 years (30 if a financial institution is involved)	None
Bank fraud	18 U.S.C. § 1344	30 years	None
Money laundering	18 U.S.C. § 1956	20 years	None
Drug trafficking, 5kg+ cocaine	21 U.S.C. § 841(b)(1)(A)	Life	10 years
Drug trafficking, 500g+ cocaine	21 U.S.C. § 841(b)(1)(B)	40 years	5 years
Felon in possession of a firearm	18 U.S.C. § 922(g)	15 years (Armed Career Criminal Act applies in some cases)	None
Receipt of child pornography	18 U.S.C. § 2252(a)	20 years	5 years
Production of child pornography	18 U.S.C. § 2251	30 years	15 years
RICO	18 U.S.C. § 1962	20 years (life if predicate carries it)	None

Sentences in real cases land somewhere between the statutory floor and ceiling, calculated through the Guidelines and adjusted by the judge under Section 3553(a). The defense work that matters is in shaping that calculation.

What to look for in a federal defense attorney

Anyone admitted to the California Bar can theoretically practice in federal court, but theory and practice diverge fast. The search for a federal criminal defense lawyer Los Angeles defendants can rely on comes down to five checks.

Actual federal admission. Verify that the lawyer is admitted to practice in the U.S. District Court for the Central District of California, not just the state bar. Federal admission requires a separate application and good standing.

Federal trial experience. A defense attorney with 30 years of state court trials may not have tried a single federal case. Federal trial procedure and evidence rules differ from state court.

Guidelines fluency. Ask the attorney how they would calculate the Guidelines in your case. The answer should be specific. They should be able to identify the base offense level, the applicable specific offense characteristics, and the likely adjustments without hesitation.

Pre-indictment work. The most valuable federal defense work often happens before charges are filed. An attorney who only takes federal cases after indictment is missing the leverage point.

A real practice, not a referral mill. Some criminal defense attorneys and law firms take federal cases occasionally and refer them out when complexity rises. You want the attorney who runs the case from start to finish.

How much does a federal criminal defense lawyer cost?

There is no standard fee for federal criminal defense representation, because the price tracks the amount of work the case requires. Most federal defense attorneys charge either an hourly rate or a flat fee set by stage of the case, and federal matters cost more than comparable state cases because they demand more hours, more filings, and more preparation.

The factors that drive the fee are consistent across law firms: the stage at which the federal criminal defense attorney is retained, the number and complexity of the federal criminal charges, the volume of discovery and evidence involved, whether expert witnesses are needed, and whether the case is heading toward a negotiated plea or a trial. A case resolved through pre-indictment intervention costs a fraction of a case that runs through a multi-week federal trial.

The only reliable way to price a specific case is to talk it through with a federal criminal lawyer. Helfend Law Group offers a free consultation on any federal matter, and fee structure is discussed openly in that first call. Call 800-834-6434.

Why clients hire the Helfend Law Group for federal criminal defense

Robert M. Helfend has practiced federal criminal defense for over 40 years and has handled more than 4,000 state and federal criminal cases since 1984. Helfend Law Group handles the full range of federal charged conduct: white collar crime (wire fraud, mail fraud, bank fraud, securities fraud, health care fraud, tax fraud), drug crimes (trafficking, manufacturing, conspiracy, importation), federal firearms cases, child pornography defense, federal sex crimes, RICO and racketeering, and public corruption.

Robert has appeared in the First Street and Roybal courthouses in Los Angeles, the George E. Brown Jr. courthouse in Riverside, and the Ronald Reagan courthouse in Santa Ana. Familiarity with how individual federal judges handle motions and sentencing, and with the AUSAs prosecuting the case, is a meaningful advantage in federal practice.

The firm reports Lead Counsel recognition, and Robert’s professional profile lists Expert Network’s Distinguished Lawyer recognition in 2018. His published federal case histories include matters involving FBI and DEA evidence. In the wire fraud and bank fraud trial discussed below, questioning of an FBI agent exposed missing evidence; the result included seven dropped counts and three convictions.

The law firm is not a referral mill and not a volume law office. Robert handles federal criminal matters personally, supported by a small legal team, from the first call through sentencing and any appeal. Clients deal with the attorney whose name is on the door.

What to do right now if you’re under federal investigation

Three rules apply from the moment you have any reason to think you’re under federal criminal investigation.

Call a federal criminal defense lawyer before you do anything else. Not a general practice attorney. Not a friend who knows a lawyer. Someone who handles federal criminal cases for a living. A federal criminal defense lawyer can step in at the earliest stage and start protecting your position before the case even reaches indictment.

Stop talking. Do not speak with federal agents. Do not discuss the situation with co-workers, business partners, or family members who might be witnesses. Communications can be subpoenaed. Statements can be charged as their own offenses.

Preserve everything. Do not delete files, messages, emails, or anything else. Do not factory reset a phone or wipe a hard drive. Do not move funds. Acts that look like efforts to destroy evidence become their own charges, often more serious than the original conduct.

Federal cases are won or lost in the early decisions. The right legal defense, retained early, changes outcomes.

To speak with Robert M. Helfend about a federal investigation or charge, call 800-834-6434. Consultations are free and confidential.

Frequently asked questions about federal criminal defense

What is a federal defense attorney?

A federal defense attorney is a criminal defense attorney who represents people accused of serious crimes in the federal court system, in United States district courts rather than state court. The work requires separate admission to the federal bar and command of federal procedure, evidence rules, and the Federal Sentencing Guidelines. Robert M. Helfend is a federal criminal defense attorney who has defended federal cases since 1984.

What is worse, federal or felony charges?

The question compares two different categories. Felony describes how serious a charge is, while federal describes which government is prosecuting it, and nearly every federal crime is charged as a felony. As a practical matter, federal cases tend to be harder on defendants than state felony cases: sentencing is stricter, there is no parole, and the prosecution arrives better resourced.

Do most federal cases go to trial?

No. Many federal criminal cases resolve through guilty pleas, and others end in dismissal. A particular case may still require a trial. Discuss the evidence, available motions, sentencing consequences, and any proposed agreement before deciding how to proceed.

Can federal charges be dismissed before trial?

Yes. A court may dismiss charges on an appropriate legal ground, or the prosecution may seek dismissal. Suppression of important evidence can affect whether the government can proceed, but suppression does not automatically dismiss a case. In the firm’s reported 12-kilogram cocaine conspiracy case, evidence analysis and expert witnesses persuaded the U.S. Attorney’s Office to dismiss the client’s case before trial. The published account does not state that a search challenge produced that result.

Does Helfend Law Group handle federal cases outside Los Angeles?

Yes. The firm is based in Los Angeles, where most of its federal work is concentrated, and it accepts federal cases nationwide. Federal law and federal procedure are the same in every district, so the defense approach travels with the case. Call the law office at 800-834-6434 to discuss a matter in any district.
