Orange County, CA Santa Ana Sex Crimes Criminal Defense Lawyer
If you are being investigated for a sex crime in Santa Ana, the case may begin before you are ever arrested. A Santa Ana police detective may call asking you to come to the station and “tell your side,” investigators may contact people who know you, or officers may seek a warrant to search your home, phone, computer, or online accounts. What you say and do during these early stages can affect a criminal case that may threaten your freedom, reputation, career, professional license, and family.

Criminal defense attorney Kristine Koo is a former prosecutor and former public defender with more than a decade of criminal law experience.

Whether you have already been arrested or have only learned that someone made an accusation against you, getting legal advice early can help you understand what is happening and begin protecting yourself.
Facing a Sex Crime Investigation or Charge in Santa Ana?
Santa Ana occupies an important place in the Orange County criminal justice system. The Central Justice Center handles felony and misdemeanor criminal matters and serves Santa Ana, Orange, Tustin, and Villa Park. The courthouse also handles various felony proceedings involving cases from throughout Orange County.
For someone accused of a sex crime in Santa Ana, the criminal process may involve an investigation by the Santa Ana Police Department or another law enforcement agency, a filing decision by prosecutors, an arrest or court appearance, and proceedings in Orange County Superior Court.
A sex crime investigation can also develop for weeks or months before formal charges are filed. During that time, investigators may interview witnesses, review electronic communications, obtain surveillance footage, collect forensic evidence, or seek search warrants.
The fact that police are investigating an allegation does not mean the accusation is true or that prosecutors can prove a crime beyond a reasonable doubt.
Contacted by a Santa Ana Sex Crimes Detective? Speak With an Attorney Before an Interview
One of the most important decisions can arise before an arrest.
A detective may tell you that the investigator simply wants to hear your version of events. You may believe that explaining yourself will clear everything up. However, speaking to investigators without first obtaining legal advice can create significant risks.
Statements can be compared against text messages, witness accounts, photographs, location information, or other evidence. An innocent mistake about a date or minor detail may later be characterized as an inconsistency. Admissions that seem unimportant may also be used to establish part of the prosecution’s case.
You generally have the right to remain silent and consult an attorney. Exercising those rights is not an admission of guilt.
An attorney can determine what investigators are seeking, evaluate whether an interview is advisable, and communicate with law enforcement when appropriate. Early representation may also provide an opportunity to preserve favorable evidence before it disappears.
Sex Crime Charges Prosecuted in Santa Ana
California sex crime laws cover a broad range of conduct. The potential punishment depends on the particular statute, the age of the complaining witness, whether force or threats are alleged, prior convictions, and other circumstances.
Rape and Sexual Assault Under Penal Code Section 261
Penal Code section 261 addresses rape under several circumstances. These include sexual intercourse allegedly accomplished against another person’s will through force, violence, duress, menace, or fear of immediate unlawful bodily injury. The statute also addresses circumstances involving unconsciousness, intoxication affecting the ability to consent, and certain other situations in which legally valid consent is absent.
Rape is a felony and can result in substantial state prison exposure and sex offender registration.
California’s One Strike law under Penal Code section 667.61 can dramatically increase punishment for certain qualifying sex offenses when specified aggravating circumstances are alleged and proven. Depending on the offense and circumstances, sentences under PC 667.61 can include 15 years to life, 25 years to life, and in certain cases even more severe punishment.
Sexual Battery Under Penal Code Section 243.4
Penal Code section 243.4 covers several forms of sexual battery. Depending on the subsection charged, an allegation may involve touching an intimate part of another person against that person’s will for sexual arousal, sexual gratification, or sexual abuse.
Some sexual battery offenses may be prosecuted as misdemeanors, while others can be felonies. Allegations involving unlawful restraint or other aggravating circumstances can significantly increase the potential punishment.
These cases frequently turn on the circumstances surrounding the encounter. Text messages, prior communications, surveillance footage, witnesses, dating history, and what each person said before and after the alleged incident may become important evidence.
Lewd Acts With a Child Under Penal Code Section 288
Penal Code section 288 criminalizes specified lewd or lascivious acts involving minors. PC 288(a) generally addresses qualifying acts involving a child under 14 when committed with the required sexual intent. PC 288(b) addresses specified conduct accomplished through force, violence, duress, menace, or fear.
These are extremely serious felony allegations. A conviction can result in years of imprisonment and sex offender registration. Depending on the circumstances, California’s One Strike sentencing law may also apply.
A defense investigation may examine forensic interviews, inconsistencies between accounts, prior statements, electronic communications, family or custody disputes, timelines, opportunity, and whether the prosecution can establish every element of the offense.
Oral Copulation, Sexual Penetration, and Continuous Sexual Abuse
Penal Code section 287 addresses unlawful oral copulation under various circumstances, while Penal Code section 289 addresses specified acts of unlawful sexual penetration. The applicable penalties vary substantially based upon the subsection charged and circumstances of the alleged offense.
Penal Code section 288.5 addresses continuous sexual abuse of a child under 14 when the statutory requirements are satisfied. Because these accusations may cover an extended period rather than a single specific date, timelines and the consistency of witness accounts can become especially important.
Certain violations of PC 287, PC 288, PC 288.5, and PC 289 may also fall within Penal Code section 667.61 when the required circumstances are proven.
Internet and Minor-Related Sex Crime Investigations
Some Santa Ana sex crime investigations arise primarily from electronic communications rather than an alleged physical encounter.
Penal Code section 288.3 addresses contacting or communicating with a minor with the intent to commit certain specified offenses involving the minor. Penal Code section 288.4 addresses arranging a meeting with a minor, or someone believed to be a minor, for specified lewd purposes when the statutory requirements are established.
Penal Code section 311.11 concerns possession or control of qualifying material depicting minors engaged in sexual conduct. Other investigations may involve Penal Code section 647.6, annoying or molesting a child, or Penal Code section 314, indecent exposure.
Digital evidence should not automatically be accepted at face value. Account ownership, device access, complete conversation histories, timestamps, downloads, cloud storage, metadata, deleted material, and the context of communications may all require investigation.
What Happens After a Sex Crime Arrest in Santa Ana?
After an arrest, the immediate process depends on the charge and circumstances. Issues involving custody, release, bail where applicable, protective orders, and the first court appearance may need to be addressed quickly.
At an arraignment, the defendant is formally advised of the charges and enters a plea. The case can then proceed through discovery, pretrial conferences, motions, negotiations, and, if no resolution is reached, trial.
Defense counsel can review police reports and prosecution evidence, investigate independently, identify favorable witnesses or evidence, evaluate constitutional issues, and determine whether motions should be filed.
A sex crime charge is an accusation. Prosecutors retain the burden of proving every element of the charged crime beyond a reasonable doubt.
Can Santa Ana Sex Crime Charges Be Reduced or Dismissed?
A person accused of a sex crime should not assume that the original charge determines the final outcome.
Whether charges can be rejected, dismissed, or reduced depends on the evidence and circumstances of the individual case. Important issues may include witness credibility, inconsistent statements, insufficient corroborating evidence, missing evidence, problems proving intent, consent when legally applicable, unlawful searches, improperly obtained statements, or failure to establish an element of the offense.
In some investigations, defense counsel may be able to communicate with prosecutors before formal charges are filed and present information that investigators did not fully consider. There is never a guarantee that prosecutors will decline to file charges, but early intervention may be valuable when significant favorable evidence exists.
Once a case has been filed, weaknesses in the evidence may become relevant to negotiations, motions, dismissal arguments, or trial.
Defending Against a Sex Crime Accusation in Santa Ana
There is no universal defense to a sex crime charge. The defense must fit the facts.
Some cases involve a dispute about whether sexual activity was consensual. Others involve an allegation that the accused maintains never occurred. Still others depend on identification, age, intent, digital communications, or whether the prosecution can prove the specific conduct required by the statute.
Potential defense issues can include false accusations, insufficient evidence, mistaken identity, credibility problems, inconsistent accounts, legally valid consent where applicable, lack of required intent, unreliable digital evidence, constitutional violations, and improper police interrogation.
Evidence beyond the accusation can become critical. Text messages, photographs, videos, GPS information, rideshare records, surveillance footage, hotel records, phone data, social media, dating applications, financial transactions, and independent witnesses may help establish what happened before or after the alleged incident.
Preserving that evidence early can be particularly important because recordings may be overwritten, messages may disappear, and witnesses’ memories can change.
Sex Offender Registration and Other Consequences of a Conviction
Jail or prison is not the only concern in a California sex crime case.
Penal Code section 290 establishes California’s sex offender registration system. California uses a tiered structure, and the applicable registration consequences depend on the qualifying conviction and other circumstances. Some convictions can result in lifetime registration.
A sex crime conviction may also affect employment, professional licensing, housing, relationships, immigration status for noncitizens, and a person’s reputation. Protective orders and restrictions concerning contact with particular individuals may also apply.
Certain serious sex crimes can qualify as strikes under California’s Three Strikes law. A strike conviction can have consequences far beyond the sentence imposed in the current case because it may increase punishment for a future felony conviction.
For professionals, executives, business owners, students, licensed professionals, and others with substantial reputational concerns, the collateral consequences of an accusation can begin even before the criminal case is resolved.
