What Is a Federal Sex Crime?
These offenses typically involve either lack of consent or acts that are illegal on their own, like prostitution, sex trafficking, or indecent exposure. Ordinarily, state authorities handle these types of charges.
Federal sex crimes often mirror state offenses, but federal prosecutors and federal agencies take the lead, creating a far more serious situation.
Federal sex crimes stand apart from other offenses due to the severe risks and heavy consequences. People convicted of these offenses often face:
- Extended incarceration, often measured in decades
- Required minimum federal prison terms for certain trafficking and exploitation offenses
- Lengthy post-prison supervision requirements
- Being required to enter a federal or state sex offender registry
- Restrictions on where they can live and work
- Permanent damage to family relationships, reputation, and employment
When Does a Sex Crime Become Federal?
Most sex crimes are generally charged at the state level. Federal jurisdiction takes over when the offense involves federal land, crosses state lines, or makes use of nationwide systems like the internet or postal services.
Federal prosecutors in Philadelphia, PAvvvvv often take over sex crime cases when one of the following applies:
- Crossing state lines in connection with unlawful sexual behavior
- Using the internet, social media, or apps as part of committing or attempting a sex offense
- Using the mail or other interstate services to send prohibited materials or messages related to a sexual crime
- Offenses on federal property, including military installations, federal prisons, or national parks
- Crimes that involve federal interests, covering conduct affecting federal personnel or federal systems
Who Investigates Federal Sex Crimes?
Federal sex crime investigations are managed by agencies that have specialized staff and powerful investigative resources. They often involve the following agencies:
- The Federal Bureau of Investigation (FBI)
- Homeland Security Investigations (HSI)
- United States Postal Inspection Service
- Military law enforcement and other federal investigative agencies
If you are contacted by one of these agencies about a sex offense, the situation has already reached a critical point. Do not engage with questioning, make comments, or authorize searches without first consulting an experienced Philadelphia, PA federal sex crime defense attorney.

Types of Federal Sex Crimes We Defend in Philadelphia, PA
Title 18 of the U.S. Code contains numerous federal sex crime statutes. Our Philadelphia, PA federal sex crime lawyers defend them all, but the charges below appear most frequently:
Sexual Abuse and Aggravated Sexual Abuse
Under federal law, sexual abuse and aggravated sexual abuse include cases involving force, threats, or victims who cannot legally consent
- Acts of sexual violence or threats of harm
- Offenses against individuals who cannot legally or physically consent due to impairment
- Sexual abuse of minors or vulnerable adults in certain federal settings
Child Sexual Exploitation and Child Pornography
Federal law is especially strict when it comes to child exploitation. Common federal allegations include:
- Sexual exploitation of children, often called production of child pornography
- Distribution and receipt of child pornography, which may involve transferring files digitally
- Possession of child pornography, whether stored on digital devices or cloud accounts
- Causing a minor to participate in explicit content or live-streamed acts
Production charges nearly always trigger mandatory minimum terms. Even simple possession can result in significant prison time, lifetime supervision, and sex offender registration.
Online Enticement and Internet-Based Offenses
Child pornography is not the only internet sex crime under Federal law. Frequently charged offenses include:
- Coercion and enticement of a minor through online messaging, texting, or digital communication
- Crossing distances to meet a person presented as a minor for unlawful sexual acts
- Transmitting explicit content to a person believed to be a minor

Undercover officers frequently impersonate minors in these investigations. Federal prosecutors can pursue charges even when the “minor” is actually an undercover agent.
Sex Trafficking of Adults and Minors
Federal law on sex trafficking is sweeping and carries exceptionally severe consequences. Sex trafficking often consists of:
- Forcing or pressuring someone to engage in sexual conduct in exchange for money, shelter, drugs, or value

- Transporting victims through threats, fraud, or coercion for exploitative purposes
