San Diego Federal & State Criminal Defense Lawyer

My office is intentionally personal. When you hire me, you are not hiring a large-volume firm where your case is passed from person to person. You are hiring me to look closely at the evidence, talk through the risks, explain your options, and build a defense strategy based on the facts of your case.

Criminal charges move quickly. The decisions you make early can affect the entire case. If you have been arrested, contacted by law enforcement, served with a target letter, charged in federal court, accused in state court, or told that you are under investigation, it is important to get legal advice before making statements or assuming the case will resolve itself.

Federal Criminal Defense in San Diego

Federal criminal cases are different from state criminal cases. They often involve indepth investigations with federal agencies, federal grand jury investigations, search warrants, subpoenas, wire communications, extensive discovery, mandatory minimum laws, federal sentencing guidelines, and prosecutors who may have spent months reviewing the case before charges are filed.

In San Diego, federal criminal defense often involves border-related investigations, drug importation allegations, alien smuggling accusations, transportation charges, illegal reentry cases, fraud investigations, firearms charges, conspiracy allegations, and other serious federal offenses. These cases may be investigated by agencies such as Homeland Security Investigations, Border Patrol, DEA, FBI, IRS, ATF, or other federal authorities.

I represent clients in federal criminal cases at every stage, including investigations, arrests, initial appearances, detention hearings, indictments, pretrial motions, plea negotiations, trial preparation, sentencing, and post-conviction matters.

Federal cases require immediate attention. If agents want to speak with you, if you receive a target letter, if your home or business is searched, or if you are arrested and taken to federal court, you should speak with a defense lawyer before answering questions. Statements made early in a federal investigation can have long-lasting consequences.

Federal Drug Crimes

I defend clients facing federal drug charges involving possession, distribution, conspiracy, importation, manufacturing, drug trafficking, and possession with intent to distribute. In San Diego, many federal drug cases are tied to border crossings, vehicle stops, parcel investigations, surveillance, confidential informants, or allegations that a person participated in a larger trafficking organization.

Federal drug cases can involve substances such as fentanyl, methamphetamine, cocaine, heroin, marijuana, prescription drugs, or other controlled substances. The type and quantity of the alleged substance can greatly affect the charge, the sentencing guidelines, and whether mandatory minimum penalties may apply.

A defense strategy may focus on whether the government can prove knowledge, intent, possession, agreement, or participation. In vehicle and border cases, a critical issue may be whether the accused person knew drugs were hidden in a car, package, bag, or compartment. In conspiracy cases, the question may be whether the client knowingly joined a criminal agreement or was simply connected to others who were under investigation.

I also look closely at search and seizure issues, statements to law enforcement, the reliability of witnesses, the client’s alleged role, and sentencing issues such as safety valve eligibility, mitigating role, criminal history, and whether a lower sentence can be argued under the facts.

Border Offenses and Immigration-Related Crimes

Because San Diego is a border district, many federal cases involve immigration-related allegations. These may include alien smuggling, transporting undocumented people within the United States, bringing noncitizens to the United States, harboring, illegal reentry, false statements, document issues, or related charges.

Alien smuggling and transportation cases are fact-specific. The government may claim that a person knowingly transported, assisted, encouraged, or helped bring someone into or within the United States unlawfully. But many important questions may remain. What did the accused person actually know? Was there payment or alleged financial gain? Was the person acting under pressure? Was the vehicle stop lawful? Were statements taken properly? Did the government overstate the person’s role?

The sentencing issues in these cases can also be serious. Allegations involving financial gain, the number of people transported, risk of injury, high-speed driving, prior convictions, or the manner of transportation can change the stakes dramatically. I work to examine both the charge and the sentencing allegations because the consequences can turn on details that are not always obvious at the beginning.

Federal Fraud and White Collar Defense

I represent clients facing federal fraud and white collar allegations, including cases involving wire fraud, mail fraud, bank fraud, tax crimes, identity theft, money laundering, embezzlement, and financial offenses.

These cases often involve large volumes of records. The government may rely on emails, bank statements, tax filings, contracts, invoices, business records, digital communications, spreadsheets, and witness interviews. A defense lawyer must be able to organize the evidence and challenge the assumptions behind the prosecution’s theory.

In many fraud cases, intent is the central issue. A business dispute, accounting problem, failed investment, billing disagreement, or financial loss is not automatically a crime. The government must prove the required criminal intent. My background in finance and accounting helps me evaluate financially complex allegations and understand how numbers, records, and business practices can be misinterpreted.

Federal Sentencing Advocacy

Sentencing is one of the most important stages of a federal case. Even when a case is resolved by plea, the final outcome may depend on guideline calculations, criminal history, mandatory minimums, enhancements, departures, variances, and the way the client’s story is presented to the judge.

I review presentence reports carefully, object to inaccurate facts when appropriate, challenge improper enhancements, and prepare mitigation materials designed to show the full person behind the case. Federal sentencing advocacy is not just about arguing law. It is about helping the court understand the client’s background, family responsibilities, work history, rehabilitation, health issues, community ties, and potential for a better future.

The government often focuses on the worst facts. My job is to make sure the court sees the whole picture.

State Criminal Defense in San Diego

I also defend clients facing California state criminal charges in San Diego County and throughout Southern California. State cases may begin with an arrest, citation, police investigation, warrant, DUI stop, domestic violence report, accusation by a complaining witness, or filing decision by the district attorney or city attorney.

State criminal charges may be misdemeanors or felonies, but even a misdemeanor can have serious consequences. A conviction can affect your employment, professional license, immigration status, firearm rights, probation conditions, travel, housing, and future record. Felony charges can carry prison exposure, strike consequences, registration requirements, and long-term damage to your reputation and freedom.

My state criminal defense practice includes homicide, assault, domestic violence, drug charges, firearms and weapons allegations, theft, fraud, burglary, robbery, sex offenses, probation violations, DUI, felony DUI, and other California criminal matters.

Violent Crime and Serious Felony Defense

I represent clients charged with serious felony offenses, including homicide, manslaughter, assault, robbery, firearms offenses, kidnapping, domestic violence-related felonies, and other violent crime allegations.

These cases often involve intense pressure. Prosecutors may rely on witness statements, physical evidence, surveillance footage, alleged injuries, forensic testing, police interviews, and emotionally charged accusations. The defense must carefully test the government’s version of events.

Depending on the facts, the defense may involve self-defense, defense of others, mistaken identity, lack of intent, unreliable witnesses, inconsistent statements, insufficient evidence, unlawful searches, improper interrogation, or overcharging. In serious cases, the defense may require investigators, experts, mitigation records, or detailed scene analysis.

Trial experience matters in these cases. I have tried more than 60 criminal defense cases before juries. That experience helps me evaluate evidence not just as it appears on paper, but as it may be presented in court. It also helps me build a defense theme that gives the client’s side of the story structure and force.

Domestic Violence Defense

Domestic violence allegations can affect a person’s life immediately. Protective orders, stay-away orders, firearm restrictions, housing issues, employment concerns, custody problems, and immigration consequences may arise before the case is fully investigated.

These cases often involve spouses, dating partners, co-parents, former partners, roommates, or family members. The facts may be more complicated than the first report suggests. Alcohol, jealousy, divorce, mutual conflict, self-defense, text messages, 911 calls, injuries, and changing witness statements may all matter.

I take domestic violence cases seriously because the consequences can be significant and the facts are often contested. I review the evidence carefully, identify weaknesses, and look for a defense or resolution that protects the client’s future.

Theft, Fraud, and Property Crimes

California theft and property crime cases can include shoplifting, grand theft, burglary, robbery, embezzlement, fraud, identity theft, receiving stolen property, vandalism, and related charges. The seriousness of the case may depend on the value of the property, the alleged conduct, prior history, whether force or fear is alleged, and whether prosecutors file the case as a misdemeanor or felony.

A defense may focus on lack of intent, mistake, consent, ownership, unreliable evidence, mistaken identity, lack of knowledge, or whether the case has been overcharged. In appropriate cases, I may also explore diversion, restitution-based resolutions, reduction of charges, or outcomes designed to avoid a lasting conviction.

Drug Charges in California State Court

California drug cases may involve possession, possession for sale, transportation, manufacturing, prescription drug allegations, or other controlled substance charges. Some cases begin with a traffic stop, search, probation search, police contact, or investigation by local law enforcement.

The defense may involve challenging the legality of the search, disputing possession, arguing lack of knowledge, questioning the intent to sell, examining lab results, or seeking treatment-based alternatives when appropriate. Not every drug case should be treated the same. The defense strategy should match the evidence, the client’s history, and the client’s goals.

DUI and Felony DUI Defense

A DUI arrest can create two immediate concerns: the criminal court case and the possible driver’s license consequences. The prosecution may rely on officer observations, driving patterns, field sobriety tests, breath testing, blood testing, body camera footage, and chemical test procedures.

I examine whether the stop was lawful, whether the officer had reasonable suspicion, whether there was probable cause for arrest, whether the tests were properly administered, and whether the breath or blood results are reliable. In some cases, timing issues, rising blood alcohol, medical conditions, testing errors, or officer mistakes may affect the strength of the prosecution’s case.

Felony DUI cases require even closer attention. A DUI may be charged as a felony if there are prior convictions, injury allegations, or other aggravating circumstances. The consequences can include custody exposure, probation conditions, license consequences, and long-term criminal record issues.

My goal is to identify the best path forward, whether that means challenging the evidence, seeking dismissal, negotiating a reduced charge, protecting driving privileges, or working toward an outcome that limits the damage to your future.

Why I Defend People Accused of Crimes

I know how stressful a criminal case can be. An accusation can affect your job, your family, your immigration status, your license, your housing, your reputation, and your sense of control over your own life. Many people come to me feeling embarrassed, frightened, angry, or overwhelmed. Some have never been in trouble before. Others have past cases and are worried about what another charge could mean.

I do not treat clients like case numbers. I take the time to understand who they are, what they are facing, and what outcome they are trying to protect. A criminal case is never just about a statute or a police report. It is about a person standing against the power of the government.

I believe in honest communication. I will not promise an outcome I cannot guarantee. I will tell you what I see, what concerns me, what may help, and what decisions need to be made. My goal is to give you clear advice so you can make informed choices at every stage of the case.

My Trial Background

Trial experience is important because it affects how a lawyer evaluates every stage of a case. A lawyer who has tried many cases understands how evidence may sound to a jury, how witnesses may hold up under cross examination, how prosecutors frame their arguments, and how small facts can change the direction of a case.

I have handled more than 60 criminal defense jury trials. I also trained in trial skills through the Colorado State Public Defender system in the Denver Trial Office, where I learned methods of jury selection and cross examination used by experienced trial lawyers.

That experience shapes how I practice. I prepare cases carefully, look for leverage, and make sure the defense is not simply reacting to the prosecution. When trial is necessary, I am ready to fight. When negotiation is the better path, I use preparation to pursue the best possible resolution.

What You Should Do After an Arrest or Investigation

If you have been arrested or contacted by law enforcement, you should be careful about what you say. Many people believe they can explain the situation and make the problem go away. Unfortunately, statements made to police, agents, investigators, or witnesses can be used against you later.

People should usually not discuss the facts of the case with law enforcement before speaking with a lawyer. Do not contact alleged victims or witnesses if there is any risk that doing so could be viewed as intimidation, tampering, pressure, or a violation of a court order. It can be helpful to preserve anything that may help your defense, including messages, photos, videos, receipts, location information, documents, and names of potential witnesses.

Most importantly, get legal advice early. Early intervention can help protect your rights, preserve evidence, address release conditions, avoid damaging statements, and begin building a defense before the prosecution’s version becomes the only version in the case.

Personal Representation From a San Diego Criminal Defense Lawyer

I built Nate Crowley Law Office to provide direct, focused criminal defense representation. I do not believe clients should feel lost in their own cases. You should understand what is happening, what the next step is, what the risks are, and what strategy is being pursued.

When I represent you, I take the time to understand your situation and your priorities. Some clients are most concerned about staying out of custody. Others are focused on immigration consequences, professional licensing, keeping their job, protecting their family, avoiding a felony, or preserving their reputation. Those concerns matter because the best defense strategy is not always the same for every client.

My role is to stand between you and the government, challenge the evidence, protect your rights, and work toward the strongest available outcome.
