720-445-9887A sex-crime accusation in Colorado can have serious consequences even before a case is resolved. An investigation or charge may affect employment, housing, education, family relationships, reputation, and future opportunities. If there is a conviction, the consequences can include jail or prison, probation, treatment, fines, and sex-offender registration when required by the offense of conviction.
If you are under investigation or have been charged in Denver, you may also be deciding whether to speak with police, how to preserve messages or other evidence, and what to do about contact from investigators. At the Law Office of Kevin Cahill, you work directly with Denver sex crimes lawyer Kevin Cahill. Kevin personally handles his clients’ cases and approaches these sensitive matters with discretion, careful preparation, and straightforward advice.
This page explains how Colorado sex-crime allegations are commonly charged, the major offense categories, how investigations may develop, potential registration and collateral consequences, and defense issues that can matter depending on the facts.
Colorado does not place all sex-related offenses in one statute. Instead, these allegations are addressed through several criminal statutes covering offenses against the person, child-exploitation offenses, prostitution-related conduct, indecent exposure, and registration-related offenses.
Some charges are misdemeanors or petty offenses, while others are serious felonies. Many qualifying convictions can also create registration obligations under Colorado’s Sex Offender Registration Act.
Common sex-crime allegations in Colorado include:
Each accusation has different elements, offense levels, potential penalties, and registration consequences. Understanding the exact statute and subsection charged is therefore an important part of evaluating the case.
When sex-offense allegations arise alongside other criminal charges, you can also learn more about our Colorado criminal defense practice.
In Colorado, conduct commonly described as rape is generally prosecuted under the sexual assault statute, C.R.S. § 18-3-402. The statute addresses knowingly inflicting sexual intrusion or sexual penetration in specified unlawful circumstances.
Colorado’s sexual assault statute can cover allegations involving circumstances such as:
Here’s a chart that summarizes these allegations:
Sexual-assault cases are therefore not limited to allegations involving overt physical force. The applicable legal theory can involve consent, incapacity, authority, physical helplessness, age, or other circumstances identified by statute.
For a more detailed discussion of these cases, see our sexual assault defense page.
Sexual assault is generally a class 4 felony under C.R.S. § 18-3-402, but different classifications can apply depending on the subsection and aggravating circumstances alleged. Certain conduct can be classified as a class 6, class 3, or class 2 felony.
Felony sexual-assault sentencing can also be subject to Colorado’s sex-offender sentencing statutes rather than only the ordinary felony sentencing range. For that reason, the charge classification alone may not describe the full potential sentencing exposure.
The defense depends on the facts and legal theory alleged. Issues can include:
Because the statute contains several different theories of liability, careful analysis begins with identifying exactly what prosecutors must prove and comparing those elements with the admissible evidence.
Colorado’s unlawful-sexual-contact statute, C.R.S. § 18-3-404, generally covers knowingly subjecting another person to sexual contact in specified unlawful circumstances. The statute is broader than what people may casually describe as “groping.”
The charge can involve:
These cases arise in many different factual settings. Some involve social encounters and alcohol; others involve medical settings, institutional environments, or allegations involving minors.
Unlawful sexual contact is generally a class 1 misdemeanor. It can become a class 4 felony when specified aggravating circumstances apply, including certain force, intimidation, threat, medical-treatment, or child-inducement allegations.
Potential issues can include:
These cases can turn heavily on context, communications, witness accounts, and the precise legal theory prosecutors have chosen.
Colorado does not use “statutory rape” as the formal title of one criminal offense. Instead, several statutes can apply to sexual conduct involving minors.
Sexual assault on a child under C.R.S. § 18-3-405 generally applies when an actor knowingly subjects another person to sexual contact when the other person is under 15 years old and the actor is at least four years older.
Colorado separately criminalizes sexual assault on a child by one in a position of trust. That offense can apply when the statutory age and position-of-trust requirements are satisfied.
Age-based cases require careful review of:
Because Colorado has multiple statutes addressing sexual conduct involving minors, these cases often require precise statutory analysis. The defense may need to examine whether the correct statute was charged, whether age-gap or position-of-trust requirements are satisfied, and whether the evidence proves each required element.
These cases may also involve delayed reports, family conflict, recorded child interviews, school or therapy records, digital communications, credibility disputes, and allegations of conduct occurring over a period of time. Each evidentiary issue should be evaluated in the context of the actual charge rather than approached with a one-size-fits-all defense.
Sexual assault on a child under C.R.S. § 18-3-405 is generally a class 4 felony. It can become a class 3 felony when specified aggravating circumstances apply, including certain force or threat allegations or when the offense is charged as part of a pattern of sexual abuse.
Special sentencing laws can also apply to qualifying convictions, so the ordinary felony classification may not fully describe the sentencing exposure.
Depending on the facts, defense issues can include:
Because the potential consequences can be substantial, careful early review of the allegations and evidence is particularly important.
Sexual exploitation of a child is governed by C.R.S. § 18-6-403. It is the Colorado offense commonly associated with allegations involving child sexual-abuse material. The statute addresses sexually exploitative material involving a person under 18 and does not require an allegation of physical contact between the accused and a child.
Depending on the subsection, Colorado law can prohibit knowingly:
Sexual exploitation of a child can carry different felony classifications depending on the conduct alleged. Production and distribution-related conduct is treated differently from certain possession or viewing allegations, and repeat offenses or moving-image material can also affect classification.
For more detailed information, see our sexual exploitation of a child defense page.
These cases often depend heavily on digital evidence, including:
Important issues can include whether the accused knowingly possessed or accessed the material, who had access to a device or account, whether files were automatically cached or synchronized, and whether law enforcement lawfully obtained and searched the digital evidence.
Indecent exposure is governed by C.R.S. § 18-7-302. It generally involves knowingly exposing genitals to another person’s view under circumstances likely to cause affront or alarm with the required sexual intent, or knowingly performing an act of masturbation exposed to another person under circumstances covered by the statute.
Allegations can arise from:
Indecent exposure is generally a class 1 misdemeanor. It becomes a class 6 felony after two qualifying prior convictions or when an adult actor more than four years older than a child under 15 knowingly commits the offense while the child is in view.
Not every allegation involving nudity automatically satisfies the indecent-exposure statute. Intent, visibility, and the surrounding circumstances can all matter.
Adult prostitution-related offenses are addressed separately from sexual assault and unlawful sexual contact. Colorado law covers conduct such as prostitution, solicitation, patronizing, pandering, and pimping, with offense levels depending on the particular charge.
These allegations frequently arise from:
Depending on the facts, potential defense issues can include whether an agreement was actually made, what communications mean in context, whether law enforcement conduct raises entrapment issues, and whether the charged offense accurately reflects the alleged conduct.
Colorado changed its statutory terminology effective July 1, 2026. Offenses previously described using “child prostitution” terminology are now framed as offenses involving commercial sexual activity with a child. The law also changed aspects of sentencing and offense terminology for soliciting, pandering, pimping, keeping a place for, inducing, and patronizing commercial sexual activity with a child. :contentReference[oaicite:7]{index=7}
These offenses are treated far more seriously than low-level adult prostitution offenses and can carry substantial felony and sentencing consequences.
A sex-crime conviction can create consequences beyond incarceration. Depending on the offense and circumstances, those consequences may include:
Professional licensing boards may also review certain convictions, particularly in regulated fields. For noncitizens, some convictions can create immigration consequences requiring separate immigration-law advice.
The collateral consequences are not identical in every case. The exact offense of conviction and the person’s circumstances matter.
One of the most significant potential collateral consequences of a qualifying sex-offense conviction is sex-offender registration. Colorado’s registration system is governed by Title 16, Article 22.
Colorado requires registration for people convicted of specified unlawful sexual offenses and certain other qualifying offenses. Equivalent out-of-state, federal, or military convictions can also create Colorado registration obligations in qualifying circumstances. :contentReference[oaicite:8]{index=8}
The exact offense of conviction is critical when determining whether registration is required.
Registration frequency depends on the offense and registrant status. Many registrants reregister annually, while others are subject to more frequent registration requirements. Additional reporting can also be required for changes of residence and other specified circumstances.
Registration and public internet posting are not the same thing. Colorado’s public website currently includes categories such as adult felony registrants, sexually violent predators, multiple offenders, and people who have failed to register or have a failure-to-register history. People whose only basis for registration is a misdemeanor sex-offense conviction or juvenile adjudication are not posted in the same general felony category. :contentReference[oaicite:9]{index=9}
Some registrants may petition a court to discontinue registration after the applicable period, while others are required to register for life and are not eligible for this relief. Current CBI guidance lists the following general petition timeframes for eligible registrants: :contentReference[oaicite:10]{index=10}
Eligible Offense Category | General Time Before Petition |
Eligible Class 1, 2, or 3 felony | 20 years from final release from court jurisdiction |
Eligible Class 4, 5, or 6 felony | 10 years from final release from court jurisdiction |
Class 1 misdemeanor unlawful sexual contact | 10 years from final release from court jurisdiction |
Other eligible misdemeanors | 5 years from final release from court jurisdiction |
Qualifying deferred sentence or adjudication | After successful completion and dismissal |
Sexually violent predators, multiple offenders, certain quarterly registrants, and other lifetime registrants may not be eligible to discontinue registration through these ordinary petition provisions.
Failing to comply with a registration obligation can itself result in a separate criminal charge. The offense level can depend in part on whether the underlying sex offense requiring registration was a felony or misdemeanor. :contentReference[oaicite:11]{index=11}
Failure-to-register cases can involve questions about notice, timing, residence information, documentation, and what the registrant was legally required to report.
See our failure-to-register defense page for more information.
Colorado’s criminal statutes of limitation are offense-specific. The general three-year rule that applies to many other felonies does not accurately describe all sex offenses.
For example, felony sexual assault under C.R.S. § 18-3-402 generally has a 20-year limitations period under current law, subject to additional statutory rules and exceptions. Sex offenses against children can have no limitations period. Other sex-related offenses can have different deadlines. :contentReference[oaicite:12]{index=12}
For that reason, an allegation should not be assumed to be time-barred simply because it concerns conduct from years ago. The exact offense, date, age of the alleged victim, and other statutory circumstances have to be reviewed.
There is no single defense strategy for every sex-offense allegation. The legal and factual issues depend on the statute, the prosecution’s theory, and the available evidence.
Sexual-assault cases may involve witness testimony, statements by the accused, physical or forensic evidence, medical findings, communications between the parties, and questions involving consent, incapacity, helplessness, age, or authority.
Digital-evidence cases can raise different issues, including who had access to a device, whether files were knowingly possessed or accessed, how forensic evidence was obtained, and whether automated caching or synchronization explains particular data.
Registration-related cases may focus on notice, timing, residence information, and compliance. Prostitution-related cases may involve the meaning of communications, whether an agreement occurred, and law-enforcement conduct.
A thorough defense analysis generally begins with reviewing the charging documents, investigation timeline, disclosed evidence, witness statements, digital or forensic material, and any constitutional issues affecting how evidence was obtained.
At the Law Office of Kevin Cahill, Kevin personally evaluates which issues are supported by the facts rather than approaching every allegation with the same defense theory.
Many people contact a sex crimes attorney before charges have been filed. You may have been contacted by a detective, asked to participate in an interview, learned through another person that law enforcement is asking questions, or discovered that police want access to a phone or other records.
Investigators may:
An investigation does not necessarily mean prosecutors will file charges. During this stage, police may still be collecting information and prosecutors may not yet have made a charging decision.
What you say or provide during that period can nevertheless become part of the evidence later. A request to “tell your side” may sound informal, but statements can be recorded, summarized in police reports, compared with other evidence, and used if charges are filed.
If law enforcement contacts you about a sex-offense allegation in Denver, speaking with a Colorado sex offense attorney before deciding whether or how to respond can help you understand the situation and avoid making decisions without knowing the potential consequences.
If prosecutors file a criminal case, the next steps depend on the charge. Proceedings may involve a first court appearance, bond or release conditions, discovery, pretrial motions, negotiations, and potentially trial.
Sex-offense cases can also involve specialized sentencing, treatment, and registration issues that may affect how different resolutions should be evaluated.
“Rape” is not generally the formal offense title used in Colorado. Conduct commonly described as rape is usually prosecuted under Colorado’s sexual assault statute, C.R.S. § 18-3-402.
Unlawful sexual contact generally involves knowingly subjecting another person to sexual contact in one of the unlawful circumstances specified in C.R.S. § 18-3-404. Depending on the facts, the case may involve consent, incapacity, physical helplessness, coercion, or other statutory circumstances.
Take the investigation seriously and consider speaking with an attorney before answering investigative questions. Preserve potentially relevant messages, records, and other evidence, and avoid deleting or altering information that could relate to the investigation.
You generally do not have to volunteer substantive statements simply because police ask to interview you. Before deciding whether to speak with investigators, you can consult a lawyer about your rights and the possible consequences of an interview.
Depending on the evidence, the defense may examine inconsistencies, motive, relationship history, identification, digital records, timing, or other evidence that contradicts or undermines the allegation. The usefulness of those issues depends on the particular facts.
No. A delay may be relevant to credibility, memory, evidence preservation, or other defense issues, but it does not automatically prevent prosecution. Colorado also has extended or unlimited limitation periods for certain sex offenses.
The Colorado offense commonly associated with what people call child pornography is generally sexual exploitation of a child under C.R.S. § 18-6-403. The statute covers several forms of conduct, including certain production, distribution, possession, viewing, and access allegations.
Knowledge can be an important element. In a digital case, issues may include whether the accused knowingly accessed, viewed, possessed, or controlled the material and whether shared devices, cached files, automatic synchronization, or other technical circumstances affect that question.
Registration consequences depend on the specific offense and disposition. They should be evaluated based on the actual charge and outcome rather than assumed from the general offense label.
No. A duty to register and public internet posting are related but distinct. Colorado publicly posts certain categories of adult registrants, while others may have registration obligations without appearing in the same public website categories. :contentReference[oaicite:13]{index=13}
Some eligible registrants may petition for relief after the applicable waiting period, while sexually violent predators and certain other registrants may have lifetime obligations without the ordinary option to discontinue registration.
That depends on the charge, evidence, applicable law, and ultimate offense of conviction. Because registration is offense-specific, the exact terms of any proposed resolution can have significant consequences and should be reviewed carefully.
There is no single timeline. Cases involving digital forensics, medical evidence, expert testimony, child witnesses, extensive discovery, or pretrial litigation may take longer than less complicated matters.
Follow all court-ordered release conditions, avoid discussing the facts with witnesses or other people who do not need to know about the case, preserve relevant evidence, and consider speaking with a defense lawyer promptly.
Sex-offense cases can involve specialized statutes, registration rules, digital or forensic evidence, and significant collateral consequences. You should understand who will actually handle your case, how the attorney communicates, and whether the lawyer is prepared to address the particular legal and evidentiary issues involved.
If you are under investigation or facing a sex-crime charge, you may be dealing with concerns about criminal penalties, registration, your career, your family, and your privacy at the same time. You should be able to discuss those concerns directly with the attorney responsible for your defense.
