Los Angeles Federal Criminal Defense Attorney: Robert M. Helfend

If you’ve 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. What you do in the first 48 hours often shapes the rest of the case.

Here’s the bottom line. Federal cases are not state cases with bigger penalties. They run on different rules, in different courthouses, with different prosecutors and a different sentencing system.

The acquittal rate at federal trial is roughly 0.4%. The work that actually changes outcomes happens before trial: pre-indictment intervention, suppression motions, Sentencing Guidelines arguments, and plea negotiations grounded in real federal experience.

Robert M. Helfend has defended federal criminal cases since 1984. He’s admitted to practice in the United States District Court for the Central District of California and the U.S. Court of Appeals for the Ninth Circuit.

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.

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 offenses the firm defends include wire fraud, mail fraud, bank fraud, securities fraud, healthcare fraud, money laundering, drug trafficking, federal firearms charges, child pornography offenses, racketeering and RICO, tax fraud, public corruption, and obstruction of justice.

Why federal cases are different from state cases

People who hire a 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.

The investigations are longer and quieter. 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 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.

The trial outcomes are different. Federal trial conviction rates exceed 80% in cases that reach a jury. Roughly 90% of federal defendants who don’t have charges dismissed enter a plea agreement. The defense attorney’s job is rarely to win at trial. It’s to prevent the indictment, suppress key evidence before trial, or negotiate a plea that minimizes Guidelines exposure.

Federal prison is different from state prison. Federal sentences are served in Bureau of Prisons custody. There is no parole in the federal system. A defendant who receives a 60-month sentence will typically serve about 85% of it.

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 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.

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 tries to gather evidence. Searches that exceed the warrant’s scope, warrants based on stale information, and warrants supported by false statements in the affidavit are all subject to challenge. An illegal search can result in suppression of every piece of evidence the government seized, which sometimes ends a criminal prosecution before it begins.

The legal process moves quickly once 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, where the active U.S. District Judges sit. 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. The grand jury must then return an indictment within 30 days under the Speedy Trial Act.

Initial appearance and detention. After arrest, you appear before a magistrate judge, usually within 48 hours. The government can move for detention under the Bail Reform Act. Defendants who are detained pretrial fare measurably worse at sentencing than those released.

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. Sentencing happens 60 to 90 days after a plea or verdict. The probation office prepares a presentence investigation report. The defense files a sentencing memorandum and objections. At the hearing, the judge calculates the Guidelines, considers the Section 3553(a) factors, and imposes a sentence.

Appeal. Federal convictions are appealed 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 your client to the U.S. Attorney’s Office on your 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.

Attacking the sufficiency of the evidence. Federal prosecutors must prove every element beyond a reasonable doubt. When the government’s evidence is built on inferences, cooperator testimony with credibility problems, or circumstantial evidence stretched too thin, the defense exposes those gaps. If the government cannot produce sufficient evidence on a key element, federal charges can be dismissed before trial.

Challenging the Guidelines calculation. Even when guilt isn’t seriously contested, the Guidelines determine the actual sentence. 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

These are statutory maximums and, where applicable, mandatory minimums. 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.

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 take federal cases occasionally and refer them out when complexity rises. You want the attorney who runs the case from start to finish.

Helfend handles the full range of federal charged conduct: white collar crime (wire fraud, mail fraud, bank fraud, securities fraud, healthcare 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 is admitted to practice in the U.S. District Court for the Central District of California and the U.S. Court of Appeals for the Ninth Circuit. He has appeared in the First Street U.S. Courthouse and the Roybal courthouse 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 has handled cases involving every major federal investigative agency operating in Los Angeles, including the FBI, DEA, IRS Criminal Investigation, ATF, Secret Service, U.S. Postal Inspection Service, and Homeland Security Investigations.

The practice is not a referral mill. Robert handles cases 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 criminal investigation for a federal crime.

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.

The best course of action is to calmly inform them that you are happy to consent to their interview, but only after speaking with your attorney first.

At this point, many federal investigators try to play hardball. They might ask you what you’re hiding, or why you have to speak with an attorney beforehand. The truth is that you are fully within your constitutional rights to do this, and it can save you from headaches that might arise if you misspeak or misremember a fact during the interview.

Another way that people find they are involved in a federal investigation is if they receive what is known as a “target letter.”

A target letter is a notice from either a federal prosecutor or the U.S. Department of Justice that you are the target of a criminal investigation.

Target letters contain information on the crime being investigated and what the federal government expects you to do next. This will usually take the form of appearing in front of a grand jury, or meeting directly with a prosecutor.

If you receive a letter from the federal government notifying you that you are a witness, subject or target in a criminal investigation, the best first move is to speak with an attorney. Remember, a target letter is not an indictment, but it could be a sign that you could be indicted soon. Your attorney will carefully review the details of your case and advise you on the best course of action.

Why do you need a federal criminal defense lawyer?

Federal charges are very serious, and a conviction could have a devastating impact on the rest of your life.

A highly skilled federal defense attorney will customize your defense strategy to the details of your case. The sooner your attorney can begin researching the evidence against you and determining the best way to fight your charges the better.
