    Types of Federal Sex Crimes We Defend in San Jose, CA

    There are dozens of federal sex crimes found in Title 18 of the U.S. Code. While our San Jose, CA federal sex crime lawyers are prepared to defend you against any of them, these are the most common charges we see:

    Sexual Abuse and Aggravated Sexual Abuse

    Federal law makes it a crime to commit sexual abuse or aggravated sexual abuse when force, threats, or individuals unable to consent are involved

    • Acts of sexual violence or threats of harm
    • Conduct involving victims who are incapacitated or unable to give consent
    • Federal-setting cases involving sexual abuse of minors or vulnerable adults

    Child Sexual Exploitation and Child Pornography

    Federal child exploitation statutes are aggressively enforced nationwide. Common federal allegations include:

    Production offenses almost always carry mandatory minimum prison sentences. Possession charges alone may still result in lengthy prison sentences, lifetime supervision, and mandatory sex offender registration.

    Online Enticement and Internet-Based Offenses

    Federal internet sex crime statutes cover far more than child pornography. Typical charges include:

    • Coercion and enticement of a minor via digital platforms including messaging apps and online chat
    • Going to meet someone thought to be a minor for prohibited sexual activity
    • Transmitting explicit content to a person believed to be a minor
    • Attempt offenses involving undercover operations or “sting” cases

    Often, these cases involve undercover agents pretending to be minors online. The absence of a real child does not prevent federal prosecutors from bringing attempt charges.

    Sex Trafficking of Adults and Minors

    Federal law on sex trafficking is sweeping and carries exceptionally severe consequences. Sex trafficking typically involves:

    • Using force, threats, or coercion to make someone engage in sexual activity in exchange for money, shelter, drugs, or anything of value
    • Moving, recruiting, or controlling a person for sexual exploitation
    • Sexual activity with a minor involving any exchange of value, even absent threats or force

    Federal trafficking charges in San Jose, CA often bring decades of imprisonment plus lifetime registration.

    Kidnapping and Transport for Sexual Purposes

    Some cases center on transporting a person across states or restricting their freedom for sexual purposes. Typical examples include:

    • Kidnapping connected to sexual misconduct
    • Transporting an individual from one state to another for prohibited sexual behavior
    • Forcing or deceiving a person into being transported for sexual exploitation

    How Is a Federal Sex Crime Different from a State Sex Crime in San Jose, CA?

    Federal sex crimes differ from state sex crimes in San Jose, CA because they take place in a separate court system, follow different procedures, and usually carry more severe punishment.

    Key differences:

    • Federal sex cases are heard in federal district courts in front of federal judges and prosecutors
    • Federal rules of evidence and procedure are generally more complicated and demanding than the rules in San Jose, CA state courts.
    • Federal investigators and courts operate with significantly larger budgets, advanced technology, digital forensics units, cross-agency task forces, and undercover operations
    • The United States Sentencing Guidelines typically impose far harsher sentencing ranges and strict mandatory minimums, and enhancements may apply depending on the victim’s age, force used, quantity of victims/images, and various other aggravating factors.

    Penalties and Consequences in Federal Sex Crime Cases in San Jose, CA

    Penalties for federal sex crimes are often measured in years or decades, and the impact rarely ends when a person is released from prison.

    Prison Sentences and Supervised Release

    These offenses frequently involve:

    • Lengthy maximum sentences under federal law
    • Mandatory minimum sentences that limit a judge’s flexibility
    • Supervised release terms that may last decades or even a lifetime

    Supervised release often includes strict rules about movement, internet use, treatment programs, and close monitoring by probation officers.

    • Publicly available information about your case
    • Restrictions on employment and housing options
