Pre-Filing Intervention Before Criminal Charges

If you have learned that police are investigating you for a crime in Orange County, you may believe there is nothing you can do until you are arrested or formally charged. That is not necessarily true.

The period before criminal charges are filed can be an important stage of a criminal case. Police may still be collecting evidence, interviewing witnesses, reviewing electronic communications, or preparing a report for prosecutors. Prosecutors may eventually review that information and decide whether criminal charges should be filed.

Pre-filing intervention allows a criminal defense attorney to begin protecting you before that decision is made. Depending on the circumstances, an attorney may communicate with investigators, prevent an unnecessary police interview, preserve favorable evidence, conduct an independent investigation, identify weaknesses in the allegations, and determine whether information should be presented to prosecutors before they make a filing decision.

The Law Office of Kristine Koo represents people under criminal investigation throughout Orange County. Criminal defense attorney Kristine Koo is a former Deputy District Attorney, former public defender, and experienced trial lawyer who has tried more than 50 jury trials. That experience can be particularly valuable when evaluating an investigation from the perspective of both the prosecution and defense.

Pre-filing intervention cannot guarantee that charges will not be filed. However, if you know you are under investigation, you do not necessarily have to wait for the prosecution to act before beginning your defense.

What Is Pre-Filing Intervention?

Pre-filing intervention is criminal defense representation that begins before prosecutors formally file a criminal complaint.

An investigation may begin with an accusation, police report, domestic dispute, workplace complaint, traffic stop, search warrant, online communication, financial transaction, or report of alleged misconduct. Investigators may collect statements, surveillance recordings, digital evidence, photographs, medical records, financial documents, or other information.

Eventually, law enforcement may submit the investigation to prosecutors for review.

Pre-filing intervention attempts to protect the person under investigation during this critical period. Depending on the facts, defense counsel may investigate the allegations independently and determine whether there is evidence or legal analysis that prosecutors should consider before making a charging decision.

The objective may be to persuade prosecutors not to file charges, to consider less serious charges, or to place the defense in a stronger position if prosecution ultimately occurs.

There May Be a Window to Act Before Charges Are Filed

Once a criminal complaint is filed, the case enters the court system. Before filing, however, the government may still be deciding whether it believes prosecution is justified and what charges are appropriate.

That can create a limited window for defense work.

For example, a police report may contain only one person’s version of an incident. A surveillance recording may contradict an accusation. Text messages may provide context that investigators did not initially receive. A witness may have information supporting self-defense. Business records may demonstrate authorization that undermines a theft allegation.

Some evidence can disappear quickly. Surveillance recordings may be overwritten. Messages can be deleted. Witnesses can become difficult to locate and memories can fade.

Early involvement allows a defense attorney to identify evidence that should be preserved rather than discovering months later that it no longer exists.

How Criminal Cases Reach Prosecutors in Orange County

Law enforcement officers investigate alleged crimes, but an officer’s belief that a crime occurred does not necessarily mean prosecutors will file the exact charges suggested by the investigating agency.

After reviewing a submitted case, prosecutors may evaluate whether the available evidence supports criminal charges and what offenses are appropriate under California law.

This is one reason the pre-filing stage can matter.

The prosecution’s initial information may largely consist of reports and evidence assembled by law enforcement. If important exculpatory or contextual evidence was never collected, prosecutors may not initially have the complete picture.

A defense attorney may be able to identify those missing facts before a charging decision is finalized.

What Can an Orange County Pre-Filing Attorney Do Before Charges Are Filed?

Pre-filing representation should be tailored to the particular investigation. It is not simply a matter of calling the police or prosecutor and asking them not to file charges.

An attorney may first determine which agency is investigating and what can reasonably be learned about the allegations. Counsel can communicate with detectives so the client does not have to handle potentially dangerous conversations alone.

The defense may then identify evidence that should be preserved. Depending on the case, that could include text messages, emails, photographs, surveillance recordings, social media communications, location information, receipts, financial records, medical information, or witness statements.

Independent investigation may reveal inconsistencies, credibility problems, alternative explanations, defenses, or evidence overlooked by law enforcement.

After evaluating the available information, counsel can decide whether communication with investigators or prosecutors is strategically appropriate. In some cases, presenting favorable evidence can be beneficial. In others, providing information could reveal facts the government did not previously know.

Effective pre-filing intervention therefore requires judgment about not only what to present, but whether and when to present it.

Can an Attorney Convince the Orange County District Attorney Not to File Charges?

No attorney can guarantee that prosecutors will reject a case. The charging decision belongs to the prosecuting agency.

However, there may be circumstances in which defense information affects how an allegation is evaluated.

Potentially important issues can include conflicting witness statements, credibility problems, surveillance video contradicting an accusation, text messages providing missing context, insufficient evidence of criminal intent, identification problems, self-defense, unreliable digital evidence, or failure of the evidence to establish an element required for the proposed offense.

Mitigating circumstances may also be relevant in an appropriate case.

The strongest pre-filing presentation is not necessarily the longest. It should focus on information that actually matters to the charging decision without unnecessarily providing the government with evidence that could strengthen its case.

Evidence That May Matter During Pre-Filing Intervention

Different investigations require different evidence.

In a domestic violence investigation, relevant evidence might include text messages, photographs, 911 recordings, body-camera footage, witness statements, or evidence concerning who initiated a confrontation.

In a sex crime investigation, communications before and after an alleged incident, surveillance video, location information, social media, dating applications, witness accounts, and forensic evidence may become important.

Theft and fraud investigations may depend on contracts, financial records, authorization, ownership, communications, or evidence concerning intent.

Internet investigations may involve devices, accounts, IP information, search warrants, electronic communications, and questions concerning who actually possessed or controlled digital material.

The defense should determine what evidence matters based on the specific elements the government would ultimately have to prove.

Should I Talk to the Police Before Charges Are Filed?

A person who believes an accusation is false may naturally want to explain everything to the investigating detective.

That can be risky.

The investigator may already possess statements, recordings, electronic communications, photographs, forensic evidence, or other information that has not been disclosed to you. You may not know why a particular question is being asked.

Even truthful statements can create problems when they are incomplete, misunderstood, or inconsistent with evidence you have not seen.

A defense attorney can communicate with law enforcement and evaluate whether an interview serves your interests. Exercising constitutional rights and obtaining an attorney should not be confused with admitting guilt.

Can My Lawyer Contact the Prosecutor Before Charges Are Filed?

Potentially, but whether that should happen depends on the case.

There is an important difference between pre-filing intervention and simply “telling your side.”

An attorney should first consider what the government appears to know, what evidence supports the defense, what information may still be missing, and whether contacting prosecutors creates strategic advantages or unnecessary risks.

When appropriate, counsel may present evidence or legal arguments explaining why charges should not be filed or why the available evidence supports a different charging decision.

In another case, the better strategy may be to avoid revealing the defense prematurely.

Kristine Koo’s experience as a former prosecutor is particularly relevant at this stage because pre-filing advocacy requires understanding how prosecutors evaluate evidence as well as how defense information may affect that evaluation.

Pre-Filing Intervention After an Arrest

An arrest does not necessarily mean prosecutors have already filed a criminal complaint.

California Penal Code section 849 recognizes circumstances in which a person arrested without a warrant may be released when insufficient grounds exist to make a criminal complaint. Certain releases under PC 849(b) are treated as detentions rather than arrests.

For someone who remains in custody, Penal Code section 825 generally requires appearance before a magistrate without unnecessary delay and establishes timing requirements subject to rules concerning weekends, holidays, and court availability.

A person released after an arrest should not automatically assume the investigation is finished. The case may still be submitted for prosecutorial review.

That period may provide another opportunity for defense counsel to investigate and evaluate whether pre-filing advocacy is appropriate.

Pre-Filing Defense for Serious Criminal Allegations

Pre-filing intervention may be particularly important when an accusation involves serious consequences.

The Law Office of Kristine Koo represents clients facing investigations involving sex crimes, domestic violence, assault, violent offenses, theft, fraud, drug crimes, internet offenses, juvenile matters, and other misdemeanor and felony allegations.

Each requires a different strategy.

A sex crime investigation may turn on consent, credibility, communications, digital evidence, or identification. A domestic violence case may involve competing accounts of a rapidly developing confrontation. A fraud investigation may depend heavily on documents and intent. A violent crime investigation may involve self-defense or witness reliability.

Pre-filing defense should focus on the elements and evidence applicable to the particular alleged crime.

Pre-Filing Intervention for Professionals and People With Careers at Risk

For professionals, executives, business owners, licensed professionals, teachers, students, and others whose reputation or career could be affected by a criminal accusation, the consequences of charges can extend beyond the courtroom.

A criminal case may create concerns involving employment, professional licensing, business relationships, educational opportunities, immigration consequences, or reputation.

These collateral concerns make careful early representation particularly important. Defense strategy should consider not only possible criminal charges but also how decisions made during the investigation could affect the client’s broader future.

California Laws That May Become Important Before Charges Are Filed

Several California statutes can become relevant during the investigation and pre-filing stages.

Penal Code section 136.1 prohibits specified attempts to prevent or dissuade victims and witnesses from reporting crimes, assisting prosecution, or testifying. Penal Code section 137 addresses bribery and certain attempts to influence testimony or information.

Penal Code sections 132 and 134 address forms of falsifying or fraudulently altering or preparing evidence. Someone under investigation should therefore preserve relevant evidence and should never attempt to manufacture, alter, or destroy evidence to improve the appearance of the case.

Penal Code section 148.5 prohibits specified knowingly false reports of crimes to law enforcement.

California law also recognizes certain pre-filing diversion programs. Penal Code section 851.87 addresses sealing arrest records following successful completion of qualifying pre-filing diversion administered by a prosecuting attorney.

These statutes illustrate why actions taken during an investigation can have significant consequences. Legal advice should be obtained before attempting to contact witnesses, investigators, or prosecutors independently.

Why Hire Former Prosecutor Kristine Koo for Pre-Filing Intervention?

Pre-filing intervention requires more than knowing criminal statutes. It requires understanding how investigations develop and how prosecutors evaluate potential cases.

Kristine Koo has experience on multiple sides of California’s criminal justice system. She has served as a Deputy District Attorney, worked as a public defender, and represented people accused of crimes as a criminal defense attorney.

She has also tried more than 50 jury trials, including serious criminal cases where defendants faced the possibility of life imprisonment.

That trial experience matters before charges are filed because an investigation should ultimately be evaluated by asking what prosecutors could actually prove in court.

When appropriate, the defense can use the period before filing to investigate allegations, preserve evidence, communicate strategically with law enforcement, and determine whether prosecutors should receive information that changes how the case is viewed.

Contact an Orange County Pre-Filing Criminal Defense Attorney

If police are investigating you, have contacted you for an interview, executed a search warrant, arrested and released you, or indicated that your case may be sent to prosecutors, you do not necessarily have to wait for criminal charges before hiring an attorney.

The period before filing may be one of the few opportunities to address evidence while prosecutors are still deciding whether and what to charge.

Attorney Kristine Koo can evaluate the allegations, communicate with investigators when appropriate, identify evidence that should be preserved, assess potential criminal exposure, and determine whether pre-filing intervention may help.

No attorney can promise that prosecutors will decline to file charges. But waiting until a criminal complaint is filed can eliminate opportunities that existed while the case was still under review.
