Tulsa Pre-File Investigation Lawyer

Reviewed by Rob Henson ·

If you believe you are under investigation for a crime in Tulsa, the time to protect yourself is before charges are filed. Police may already be interviewing witnesses, reviewing records, examining phones or other digital evidence, gathering surveillance footage, or trying to get a statement from you while prosecutors decide whether the evidence supports criminal charges.

That early stage can be one of the most important periods in a criminal case. Working with a criminal defense lawyer before charges are filed gives you an opportunity to avoid damaging mistakes, preserve favorable evidence, understand what investigators are doing, and prepare for what may come next.

What Is a Pre-File Criminal Investigation?

A pre-file investigation is the period when law enforcement is investigating suspected criminal conduct before formal charges have been filed against you. You may know that you are under investigation because a detective called you, officers came to your home or workplace, witnesses have been contacted, or someone told you that police are asking questions about you.

In other situations, the signs are less obvious. You may have been present when something happened, your name may have appeared in someone's statement, your phone number may show up in an investigation, or police may be trying to determine whether the available evidence connects you to an alleged crime.

During this period, investigators may conduct interviews, collect documents, obtain search warrants, review electronic communications, examine surveillance video, request records, conduct forensic testing, and compare different witnesses' accounts. The investigation may still have significant gaps, and the version of events being presented to law enforcement may be incomplete or wrong.

If Police Want to Question You

If police or investigators want to ask you substantive questions about suspected criminal conduct, you should decline to answer questions and ask to speak with an attorney. Trying to explain the situation on your own can create evidence that did not previously exist.

People frequently assume that talking will help because they are innocent, because the police seem to have misunderstood what happened, or because a detective says that an interview is an opportunity to give “your side.” A statement that seems harmless when you make it can later be compared with other statements, records, video, phone data, or physical evidence in ways you did not anticipate.

Investigators may also use some deceptive tactics during questioning. You should not assume that everything an investigator tells you about the evidence, what another witness said, or what will happen if you cooperate is necessarily a complete description of the situation.

If a detective calls, leaves a business card, asks you to come to the station to “clear things up,” or contacts a family member looking for you, do not try to talk your way out of the investigation. Speak with a criminal defense lawyer before deciding whether any response should be made.

Why Getting a Lawyer Involved Early Matters

Many people wait until an arrest warrant has been issued or charges have appeared on a court docket before contacting a lawyer. By then, useful evidence may have disappeared, witnesses' memories may have changed, surveillance video may have been overwritten, and the person under investigation may already have made statements that become part of the State's case.

Early representation creates an opportunity to evaluate the situation while the investigation is still developing. Depending on the facts, Rob may be able to identify evidence that needs to be preserved, locate witnesses, review records supplied by the client, communicate with investigators or prosecutors, and decide whether presenting defense information before a charging decision would help or hurt the client.

Timing matters, but early intervention does not mean immediately contacting the police or prosecutor in every case. Sometimes the better course is to gather information first, preserve evidence, and avoid revealing a defense theory before understanding what the investigation is about.

What a Lawyer Can Do Before Charges Are Filed

Pre-file representation is different from defending a case that is already pending in court. The work is often more investigative and strategic because the State has not yet committed itself to a formal charge and the ordinary court process has not begun.

Depending on the circumstances, Rob may:

  • Advise you about police contact and requests for an interview.
  • Communicate with investigators or prosecutors when doing so serves your interests.
  • Identify and interview potential defense witnesses.
  • Preserve surveillance footage, photographs, messages, records, and other evidence that may disappear with time.
  • Review timelines and compare witness accounts for inconsistencies.
  • Examine documents, electronic communications, financial records, medical records, or other evidence relevant to the allegation.
  • Help determine whether there is information the prosecutor should receive before making a filing decision.
  • Prepare for the possibility of an arrest warrant, bond proceeding, or formal criminal case.
  • Advise you about subpoenas, search warrants, requests for records, or efforts to obtain property or electronic devices.

Those steps are not appropriate in exactly the same form in every investigation. Pre-file representation begins with determining what is known, what is not known, what evidence can realistically be obtained, and what action is most likely to protect the client's position.

What Pre-File Representation Does Not Do

Before charges are filed, there is no pending criminal prosecution in which the defense can demand the State's ordinary criminal discovery. A lawyer may have to investigate independently, work from information supplied by the client, preserve evidence from third parties, and decide whether there is a sound reason to approach law enforcement or the prosecutor.

Hiring a lawyer before charges are filed also does not automatically mean police are legally prohibited from trying to contact you. If investigators contact you directly about suspected criminal conduct, you should decline to answer their questions and tell them you want to speak with your lawyer.

A lawyer also cannot guarantee that an investigation will end without charges. The filing decision belongs to the prosecuting authorities, and some investigations will result in charges regardless of what the defense presents.

Preserving Evidence Before It Disappears

Evidence that exists during an investigation does not necessarily remain available indefinitely. Business surveillance systems may overwrite video, text messages or other communications may be lost, witnesses may become difficult to locate, and memories become less reliable with time.

The defense may need to identify those sources quickly. A receipt, location record, photograph, video, medical record, work record, electronic communication, or witness may become important only after the accusation is compared carefully with where the client was, what the client was doing, and what the State claims happened.

You should not delete, alter, hide, destroy, or ask someone else to change potential evidence. Preserving relevant material is very different from interfering with evidence, and a lawyer can help determine what should be retained and how it should be handled.

When Contacting the Prosecutor Before Filing Makes Sense

There are investigations where giving the prosecutor reliable defense information before a filing decision is made can be useful. Evidence showing mistaken identity, an unreliable accusation, an innocent explanation for financial activity, a critical timeline problem, unavailable proof of an essential fact, or another substantial weakness may affect how the investigation is viewed.

There are also cases where approaching the State too early would accomplish little or could reveal information that is better kept confidential. The decision to contact investigators or prosecutors should be strategic, not automatic.

Pre-file representation is not simply about “telling the prosecutor your side.” It is about deciding whether there is reliable information that should be presented, what should remain confidential, and when taking action is more useful than remaining silent.

Felony and Misdemeanor Pre-File Investigations

Pre-file representation can matter in both felony and misdemeanor investigations. The immediate stakes are usually greater in a serious felony investigation, but a misdemeanor accusation can still affect employment, professional licensing, family relationships, reputation, and other important parts of a person's life.

Pre-file investigations may involve allegations of violent crimes, sex offenses, drug crimes, embezzlement or fraud, burglary or theft, conspiracy, assault and battery, and many other criminal offenses. The investigative strategy depends on the particular accusation and the evidence being collected, not simply on whether the potential charge is labeled a felony or misdemeanor.

Signs You May Need a Lawyer Before Charges Are Filed

You should consider the situation serious enough to obtain legal advice if:

  • Police or detectives have asked to interview you.
  • Officers have come to your home or workplace looking for you.
  • You learn that witnesses are being questioned about you.
  • You receive a subpoena or another formal demand for information or records.
  • Investigators ask for your phone, computer, documents, property, or access to an account.
  • Someone tells you that your name has come up in a criminal investigation.
  • You believe law enforcement is trying to determine whether you were involved in an alleged offense.
  • A family member, employer, coworker, former partner, alleged victim, or other person tells you that investigators have contacted them about you.

A subpoena, warrant, or other legal process should not be ignored. Contact a lawyer promptly so the document and the circumstances surrounding it can be reviewed before you decide how to respond.

Rob Henson's Experience With Pre-File Investigations

Rob Henson has represented clients during pre-file investigations involving allegations of first-degree murder, first-degree rape, lewd molestation of a child, embezzlement, federal tax evasion, insurance fraud, possession of controlled drugs with intent to distribute, distribution of a controlled drug, assault and battery, solicitation of prostitution, conspiracy, prescription drug fraud, knowingly concealing stolen property, second-degree burglary, and other felony allegations.

His pre-file work has included matters in which the investigation ended without formal charges being filed against the client. Past results do not predict what will happen in another investigation, but that experience illustrates why the period before filing deserves the same careful attention as a case that is already in court.

Frequently Asked Questions About Pre-File Investigations

Should I talk to the police if I have done nothing wrong?

You should decline to answer substantive questions and ask to speak with a lawyer. Innocence does not prevent a statement from being misunderstood, taken out of context, compared unfavorably with later evidence, or used to focus an investigation more directly on you.

Can I hire a criminal defense lawyer before I am arrested?

Yes. You do not need to wait for an arrest or formal criminal charge to retain a lawyer, and pre-file representation is specifically intended for the period while an investigation is still underway.

A lawyer can advise you about contact with investigators, preserve evidence, evaluate what is known about the allegation, and prepare for a possible filing or arrest. What the lawyer actually does will depend on the facts and on how much information about the investigation is available.

Can a lawyer keep charges from being filed?

No lawyer can promise that an investigation will end without charges. Some investigations do end without a case being filed, and in the right circumstances defense evidence or early legal work may affect the prosecutor's decision, but the result depends on the evidence and the particular investigation.

Does my lawyer get the police reports before charges are filed?

There is no pending prosecution before charges are filed in which the defense can use the ordinary statutory criminal discovery process to demand the State's file. That makes independent investigation, evidence preservation, client records, witness information, and careful decisions about communication with law enforcement especially important during the pre-file stage.

What if police have a search warrant?

Do not physically interfere with officers executing a warrant, and do not try to destroy, hide, or alter evidence. You should decline to answer substantive investigative questions and contact a lawyer as soon as possible so the warrant, the search, and what was seized can be reviewed.

What if I receive a subpoena?

Do not ignore it. A subpoena can create legal obligations and deadlines, so have a lawyer review it before producing records, appearing for testimony, or communicating with investigators about the underlying allegations.

Are police officers allowed to lie during an investigation?

Investigators may use some deceptive tactics during questioning, and the fact that an officer used deception does not automatically make a statement inadmissible. The legality of an interrogation and the admissibility of a statement depend on the surrounding circumstances.

The practical advice is simpler. Do not try to determine during an interview whether an investigator is telling you everything, bluffing, or accurately describing the evidence. You should decline to answer questions and ask to speak with a lawyer.
