A detective may leave a voicemail asking you to “come in and clear a few things up.” You might hear from an ex-partner or coworkers that the police are asking questions. Even if you have not been arrested and no criminal case appears under your name, investigators may still be interviewing witnesses, collecting evidence, or preparing a case for prosecutorial review.
This is often when you can use the time during a pre-file investigation to your advantage.
If you are under investigation for a sex crime in San Diego County, your actions now may influence the evidence police gather and what a prosecutor reviews. At The Law Offices of Kerry L. Armstrong, APLC, we help clients use this pre-charge window deliberately, before a detective’s next request or a prosecutor’s filing decision narrows the situation.
Key Takeaways
Sex Crime Investigation In San Diego: Key Points Before Charges Are Filed
A sex crime investigation in San Diego County can move forward for weeks before anyone is arrested or charged. Here is what matters most during that pre-filing window.
- Filing is a prosecutor’s decision, not an automatic result of a police report, and prosecutors may file, decline, or send the case back for more investigation.
- Agreeing to a detective interview or contacting the accuser before getting legal advice can create new statements that investigators may later use as evidence.
- Preserving texts, emails, photos, call logs, and location records matters, because messages, accounts, and surveillance footage can disappear quickly.
- A few quiet weeks do not mean the investigation is over, and California’s time limits for sex offenses vary based on the alleged offense and other factors.
The Waiting Is The Hardest Part. You Don’t Have To Do It Alone.
Knowing police may be asking questions about you, with no charges and no answers, can feel unbearable. Our San Diego defense team can step in before a filing decision is made, and we are ready to listen before you decide what to say or do next.

A pre-file investigation is the stage when police investigate allegations before a prosecutor files a criminal complaint. Police may interview witnesses, review digital records, seek warrants, collect forensic evidence, and prepare a report recommending charges.
A California criminal case usually begins when a prosecutor files a complaint after reviewing law enforcement’s report. Until then, there may be no public case number or court date, even as investigators continue their work.
In San Diego County, prosecutors may file a complaint, decline to prosecute if evidence is insufficient, or request further investigation. Filing is a prosecutorial decision, not an automatic result of a police report. Before charges are issued, a prosecutor reviews the investigation to determine if the evidence supports moving forward.
That review is why the period before filing matters.
Before You Return a Detective’s Call, What Should You Do First?
Your priority is to avoid making new statements or communications that could become evidence while preserving records that may help establish what actually happened. Being investigated by police can trigger an urge to explain yourself, confront the accusation, or delete messages, which can make matters worse.
Before responding to anyone involved, take these practical steps:
- Do not agree to a detective interview before getting legal advice;
- Do not contact the accuser to demand an explanation, retraction, or closure;
- Preserve texts, emails, photos, call logs, location records, and social media rather than deleting or editing them;
- Privately organize dates, locations, witnesses, and communications for your attorney while the details remain fresh; and
- Save any voicemail, business card, case number, detective name, or warrant paperwork you receive.
The point is to protect context and avoid creating statements that investigators may later interpret differently than you intended.
What Can a Defense Lawyer Actually Do Before a Filing Decision?
Defense work can begin before charges are filed, though no lawyer can guarantee charges will be avoided.
Depending on the facts, we may determine which agency is investigating, take over appropriate communications with detectives, investigate whether the police account may be missing information, and assess whether there is anything useful to present before a filing decision. In other cases, contacting investigators or prosecutors may offer no strategic benefit.
Sometimes the better decision is not to engage with investigators while the defense gathers information independently. The important part is making that choice based on the facts rather than fear, pressure, or the urge to clear things up.
What Evidence Can Disappear While You Wait?
Sex crime investigations often depend on details that can disappear quickly. Messages may be deleted, surveillance footage overwritten, social media accounts removed, and memories can fade over time.
Depending on the allegation, useful evidence may include:
- Communications before and after the event,
- Location data,
- Call history,
- Photographs,
- Witnesses,
- Relationship context, and
- Forensic or medical records.
We compare accounts to the timeline and look for inconsistencies as the investigation progresses.
Early preservation is important because a screenshot rarely tells the full story. The surrounding conversation, date sequence, or related records may provide context that is difficult to recover later.
Does Silence from the Police Mean the Investigation Is Over?
No. A few quiet weeks do not necessarily mean the investigation has ended. Detectives may still be collecting evidence, waiting for records or forensic work, interviewing witnesses, or responding to a prosecutor’s request for additional investigation. In San Diego County, prosecutors can return a matter for more investigation rather than immediately filing or rejecting it.
There is also no single charging deadline for every sex offense. California’s limitation periods depend on the alleged offense, the accuser’s age, the date of the alleged conduct, and other statutory rules. Some specified felony sex offenses may be prosecuted without the ordinary limitations period, subject to the statute’s applicability provisions.
A period of inactivity does not mean the investigation has ended. Counsel can assess the situation and determine if there are discreet ways to check the status without drawing unnecessary attention.
If Charges Are Filed, Who Prosecutes the Case and Where Does It Go?
The filing process depends on the alleged offense and its location. The San Diego County District Attorney’s Office prosecutes felonies countywide and most misdemeanors outside San Diego city limits. The San Diego City Attorney’s Office prosecutes misdemeanors within the City of San Diego.
San Diego County criminal cases are handled in Downtown, Vista, El Cajon, and South Bay. Complaints are generally filed in the courthouse closest to where the alleged offense occurred, although certain cases are at times filed in the downtown courthouse no matter where the incident occurred in the county.
After a complaint is filed, an arraignment follows. The formal pretrial stage includes discovery, motions, negotiations, and, for felonies, usually a preliminary hearing.
The weeks before filing are when police and prosecutors may still be deciding whether to pursue a case and what charges to file.
How Does Trial Experience Shape the Way We Review a Case Before Filing?
Early case review is different when you know what eventually matters in a courtroom. We look for material contradictions, missing context, weaknesses in corroboration, digital evidence that changes the chronology, and facts that deserve investigation before the accusation hardens into the prosecution’s initial filing theory.
Kerry L. Armstrong is certified by the State Bar of California as a criminal law specialist, has tried over 110 jury cases, and focuses on sex crime defense. He was named the 2013 and the 2026 Trial Lawyer of the Year by the San Diego County Criminal Defense Bar Association. This courtroom experience guides the firm’s early case evaluation, helping us identify which factual gaps and evidentiary issues may become critical later.
We also help clients manage the uncertainty that comes with this stage. If investigators call again, request a meeting, or make another inquiry, you should not have to decide in real time how to respond while wondering what the police already know.
