What to Do If You Are Under Criminal Investigation in Orange County

Learning that you are the target of a criminal investigation can create immediate uncertainty. Are the police planning to arrest you? Should you speak with the detective? What evidence do investigators have? Has the case already been sent to prosecutors? Can an attorney do anything before charges are filed?

If you believe law enforcement is investigating you in Orange County, you do not have to wait until an arrest or criminal complaint to seek legal representation. In some cases, the period before charges are filed provides important opportunities to protect your rights, preserve favorable evidence, communicate with investigators, and evaluate whether information should be presented before a prosecutor makes a filing decision.

The Law Office of Kristine Koo represents individuals during this critical pre-filing stage. Criminal defense attorney Kristine Koo is a former prosecutor and former public defender who has handled serious criminal cases and tried more than 50 jury trials. Her experience allows her to evaluate an investigation from both sides and consider not only what police believe happened, but what prosecutors could ultimately prove in court.

When the government is already building its case, waiting is not always the best defense strategy.

Are You the Target of a Criminal Investigation in Orange County?

Police do not always tell someone directly that they are the target of an investigation.

You may first become suspicious when a detective calls and asks to “hear your side” of an incident. Police might contact your spouse, employer, friends, coworkers, business partners, or former romantic partner. Investigators might request access to your phone, ask you to come to a police station, obtain surveillance footage, seek financial records, or execute a search warrant.

You may also learn that an alleged victim has made a police report or that detectives are interviewing witnesses about you.

These developments should not automatically be interpreted as proof that criminal charges will be filed. An investigation is the process of gathering evidence. That evidence may support an allegation, contradict it, or leave significant questions unresolved.

The important point is that the investigation may already be developing before you ever see a courtroom.

What Should You Do If Police Are Investigating You?

One of the first things to do is avoid making the situation unnecessarily worse.

Preserve potentially relevant evidence. Text messages, emails, photographs, videos, receipts, social media communications, employment records, financial records, location information, and other materials could become important to the defense. Evidence that seems unfavorable when viewed alone may tell a different story when placed in context.

Do not delete or alter evidence because you are worried about what investigators might find.

You should also avoid confronting the person who made the accusation or attempting to persuade witnesses to change their accounts. California Penal Code section 136.1 prohibits certain conduct intended to prevent or dissuade victims and witnesses from reporting crimes, assisting prosecutions, or participating in legal proceedings. Conduct during an investigation can potentially create allegations separate from the crime originally being investigated.

California Penal Code sections 132 and 134 also address certain forms of false or fraudulently altered evidence.

Before deciding how to respond to investigators, consider obtaining advice from a criminal defense attorney who can assess the situation without the pressure of a police interview.

Do Not Try to Talk Your Way Out of a Criminal Investigation

People who believe they are innocent often think talking to police can only help.

That assumption can be dangerous.

A detective requesting an interview may already have spoken with witnesses, reviewed messages, watched surveillance footage, or examined other evidence. You may be asked questions without knowing what investigators already know or believe.

Even truthful statements can create problems. A person may forget a detail, estimate a date incorrectly, misunderstand a question, or make a statement that appears inconsistent with another piece of evidence.

You generally do not have to participate in a voluntary police interview merely because a detective wants to speak with you.

You also should not assume a conversation is harmless because police have not read Miranda warnings. Miranda generally concerns custodial interrogation. A voluntary statement can potentially be used even when no Miranda warning was required.

Whether there is a strategic reason to communicate with investigators should be considered with counsel rather than decided during an unexpected telephone call or police visit.

What Can an Orange County Criminal Defense Attorney Do Before Charges Are Filed?

Pre-filing representation can involve much more than telling a client not to speak with police.

The first step may be determining which agency is investigating and what investigators want. An attorney can communicate with a detective so the client does not have to handle potentially consequential conversations alone.

Counsel may then evaluate whether an interview should be declined, whether communication should occur only through the attorney, and whether there is information investigators or prosecutors should receive.

A pre-filing defense can also include identifying and preserving evidence, locating witnesses, reviewing communications, examining surveillance footage, investigating the accusation, and developing information that may contradict or provide context for the allegations.

If an arrest appears possible, counsel can also evaluate how to address the situation and whether arrangements can be made concerning a surrender rather than leaving the client completely uncertain about what may happen next.

Every investigation is different. Effective pre-filing representation requires deciding not simply what can be done, but what should be done without unnecessarily revealing the defense.

Preserving Evidence Before It Disappears

Early evidence preservation can be one of the most important advantages of obtaining representation during an investigation.

Surveillance systems may overwrite recordings. Businesses may dispose of records. Electronic devices may be replaced. Social media accounts can change. Witness memories can become less reliable with time.

Consider an accusation arising from an encounter outside a restaurant, hotel, nightclub, residence, workplace, or retail business. Nearby cameras might contain evidence affecting the credibility of a witness or establishing when people arrived and left. Waiting months to investigate may mean that footage no longer exists.

The same principle applies to digital communications. A complete text conversation may provide context that is missing from selected screenshots presented to police.

A defense attorney can identify potentially important evidence and determine whether steps should be taken to preserve it before it becomes unavailable.

Can a Defense Attorney Contact Police or Prosecutors Before Charges Are Filed?

Depending on the circumstances, yes.

Law enforcement may complete an investigation and submit reports to a prosecuting agency. Prosecutors then evaluate whether criminal charges should be filed.

There are cases in which defense counsel may decide to provide evidence or information before that decision is made. This might include communications contradicting an accusation, documents establishing an alternative explanation, evidence affecting witness credibility, records addressing disputed events, or legal analysis explaining why an essential element of an offense cannot be established.

Pre-filing advocacy does not guarantee that prosecutors will reject or reduce a case.

It is also not appropriate in every investigation. Providing information too early can reveal defense strategy or give investigators an opportunity to address weaknesses they otherwise might not recognize.

The decision to approach investigators or prosecutors should therefore be strategic rather than automatic.

How Does a Prosecutor Decide Whether to File Criminal Charges?

Police officers and prosecutors perform different functions in the criminal justice process.

Law enforcement investigates allegations and gathers evidence. Investigators may prepare reports and submit a case to the appropriate prosecuting agency. A prosecutor then evaluates the evidence and determines whether criminal charges should be filed.

A police investigation therefore does not itself mean that a criminal charge has been filed.

During this stage, prosecutors may consider witness statements, physical evidence, electronic evidence, credibility issues, available defenses, and whether the admissible evidence supports the elements of a particular offense.

This distinction is one reason pre-filing representation can matter.

When appropriate, defense counsel may be able to identify evidence or legal issues before the government’s initial version of the case becomes a filed prosecution. There is never a guarantee that intervention will prevent charges, but the period before filing should not automatically be treated as a period in which the defense can do nothing.

Search Warrants, Phones, Computers and Digital Evidence

For some people, the first unmistakable indication of a serious investigation is the execution of a search warrant.

California Penal Code section 1524 identifies circumstances under which a search warrant may be issued. Depending on the allegations, investigators may seek evidence from a residence, vehicle, business, computer, phone, electronic account, or other location.

Do not physically interfere with officers executing a warrant. The legality of the search can be evaluated afterward.

California Penal Code section 1538.5 provides procedures for seeking suppression of evidence obtained through an unreasonable search or seizure in a criminal case. Whether a particular search can successfully be challenged depends on the warrant, supporting information, execution of the search, and applicable constitutional law.

Digital evidence has also become central to many investigations. Texts, emails, photographs, videos, internet activity, social media, financial transactions, cloud data, and location information can become evidence.

Investigators may interpret isolated communications as proof of intent or knowledge. The defense should consider the complete context, including surrounding conversations, dates, participants, account access, and other evidence.

A warrant means judicial authorization was obtained for a search. It does not establish that the target is guilty.

Can Police Arrest You While the Investigation Is Still Pending?

Yes. Police do not necessarily have to complete every possible investigative step before an arrest if the legal requirements for an arrest are satisfied.

Other investigations continue without an immediate arrest and are later submitted to prosecutors for review.

This uncertainty can be one of the most difficult parts of being under investigation. A person may continue working and caring for family while wondering whether police will appear unexpectedly.

An attorney cannot promise that an arrest will not occur. Counsel may, however, communicate with investigators, assess available information, and sometimes address arrangements if an arrest or voluntary surrender becomes necessary.

Preparing for that possibility is different from simply waiting for it.

Criminal Investigations Handled by the Law Office of Kristine Koo

Pre-filing representation can be important in investigations involving both misdemeanors and serious felonies.

The Law Office of Kristine Koo handles criminal matters involving sex crimes, domestic violence, assault and battery, theft, fraud, drug offenses, internet crimes, juvenile cases, and other criminal allegations.

The defense strategy depends heavily on the type of investigation.

A domestic violence investigation may involve competing accounts, injuries, photographs, prior communications, and witness credibility. A sex crime investigation may involve delayed allegations, digital evidence, forensic issues, recorded communications, and sharply disputed accounts of what occurred.

Financial and theft investigations may depend on whether prosecutors can establish fraudulent or criminal intent rather than merely suspicious transactions. Internet investigations may raise questions about who possessed or controlled a particular account or device.

Investigations involving multiple people can present additional issues. California Penal Code section 182 addresses criminal conspiracy and can become relevant when investigators claim multiple people agreed to commit a crime.

The defense should be built around the actual evidence rather than assumptions based solely on the accusation.

Why Former Prosecutor Kristine Koo for an Orange County Pre-Filing Investigation?

The pre-filing stage requires looking ahead.

Kristine Koo has served as a Deputy District Attorney, worked as a public defender, and represented criminal defendants in private practice. She has tried more than 50 jury trials, including serious criminal cases.

Her prosecutorial experience provides insight into how criminal allegations can be evaluated from the government’s side. Her defense and trial experience provides another perspective: what evidence can actually withstand scrutiny when witnesses are questioned, legal challenges are raised, and prosecutors are required to prove their allegations.

That combination is particularly relevant before charges are filed.

A pre-filing attorney should not simply react to what investigators are doing. The defense should evaluate where the investigation may be going, which evidence needs to be preserved, what information should remain confidential, whether communication with the government may help, and how today’s decisions could affect a future criminal case.
