What to Do in the First 24 Hours When Someone Goes Missing
If you're reading this because someone you love is missing, take a breath. What you do in the first hours matters, but you don't have to do everything at once, and you don't have to do it alone. This guide will walk you through what to do, in the order it needs to happen, written by people who understand what you're going through.
The First Hour: Confirm and Report
The first thing to know: there is no waiting period to file a missing persons report. This is a myth. The 24-hour rule does not exist in U.S. law. If you believe someone is missing, you can report it immediately, and you should.
Try to reach them first
Before calling police, take a few minutes to:
- Call their phone, then text. Try multiple times.
- Contact close friends, family members, coworkers, or anyone they may have seen recently.
- Check their usual places: home, work, regular spots, their car if it's accessible.
- Check social media for recent activity or check-ins.
- Look for a note, voicemail, email, or text that might explain where they are.
If none of these turn up answers within 30 to 60 minutes, move forward with reporting. Don't second-guess yourself. Police would rather take a report that turns out to be nothing than miss the critical window for someone in real danger.
File a police report
Call your local police department's non-emergency line, or if you believe the person is in immediate danger, call 911. You can also go to the police station in person.
When you file the report, you'll be asked to provide:
- Full legal name, date of birth, and physical description
- A recent, clear photograph (a face shot from the last few weeks is best)
- What they were last wearing, if you know
- Where and when they were last seen
- The make, model, color, and license plate of their vehicle, if applicable
- Their phone number, email, and social media handles
- Any medical conditions, medications, or mental health concerns
- Whether they have a history of going missing or any reason to disappear voluntarily
- Names and contact info for friends, coworkers, or anyone they may be with
Get the case number and the name of the officer taking the report. Write these down. You will reference them many times.
Build the Information You'll Need
Once a report is filed, the work shifts. Police will begin their investigation, but families often play a critical role in keeping a case moving. Here is what to gather and document while it's fresh.
Create a missing person fact sheet
This is a single document you'll share repeatedly. Include:
- Full name and any nicknames
- Age, height, weight, eye color, hair color
- Distinguishing features (tattoos, scars, piercings, birthmarks)
- A clear, recent photo
- Date and location last seen
- What they were wearing
- Vehicle information
- Contact information for the lead investigator
- A tip line or phone number where leads can be called in
Keep this document on your phone so you can send it to anyone, anytime.
Submit to NamUs
NamUs is the National Missing and Unidentified Persons System, run by the U.S. Department of Justice. It is free, and any family member can submit a case at namus.nij.ojp.gov. Cases in NamUs are searchable by law enforcement, medical examiners, and the public. It can also help match missing persons with unidentified remains.
You do not need to wait for police to do this. You can submit a case yourself.
Contact relevant national organizations
Depending on the situation, reach out to:
- National Center for Missing & Exploited Children (1-800-843-5678) if the missing person is under 21
- Black and Missing Foundation if you believe the case isn't getting appropriate attention due to race
- NamUs for any missing person, regardless of age
Spread the Word
Sharing information widely, quickly, and accurately can be one of the most powerful tools you have. But how you share matters.
Post on social media, but do it right
Include
- A clear, recent photo
- Full name and age
- Last seen date, time, location
- Last known clothing
- Medical conditions, if relevant and comfortable sharing
- A case number or tip line, never a personal phone number
Avoid
- Personal addresses
- Speculation about what happened
- Details about ongoing romantic, legal, or family conflicts
- Photos of the missing person in vulnerable states
Pin the post to your profile so it doesn't get buried. Update it as new information comes in.
Ask others to share
You don't need a viral post. You need the right people to see it. Ask family, friends, coworkers, and community groups to share within their networks. Local Facebook groups for your city, neighborhood apps like Nextdoor, and community pages often reach people who might have actually seen something.
Reach out to local media
Local news stations, newspapers, and radio stations often cover missing persons cases, especially in the first 48 hours. Send them the fact sheet, the photo, and your contact information. If your loved one is from a marginalized community, also reach out to community-specific publications and journalists.
What to Expect From Law Enforcement
Police investigations of missing persons can feel slow, opaque, or frustrating. Knowing what's normal helps.
What should happen
- An officer takes a detailed report
- The missing person is entered into the National Crime Information Center (NCIC) database
- Investigators may interview people who saw the missing person recently
- Cell phone records, financial activity, and surveillance footage may be requested
- A detective is typically assigned within 24 to 72 hours
What you can ask for
You have the right to:
- Regular updates from the assigned detective
- The detective's direct contact information
- A copy of the police report
- Clarification on what's being done
If you feel the case isn't getting attention, you can escalate. Ask to speak with a supervisor. Contact your local elected officials. Reach out to advocacy organizations that specialize in your situation.
Taking Care of Yourself
This part is just as important as the rest.
In the first 24 hours, you may not feel hunger, you may not sleep, and you may feel like every minute you spend resting is a minute you should be searching. That's a normal response. It's also unsustainable.
A few things to try:
- Designate a point person. Choose one trusted family member or friend to coordinate communications, take phone calls, and field offers of help. This protects your bandwidth.
- Eat and drink something, even if it's small. You will need your body and mind to be functional for what's ahead.
- Accept help. People will want to do something. Let them bring food, watch your other children, run errands, or share posts. You don't have to manage them. Tell them what you need.
- Avoid spiraling alone online. Information moves fast and not all of it is accurate. Stick to verified sources and trusted people.
If you need someone to talk to, call 988 (the Suicide & Crisis Lifeline). It's not only for suicidal thoughts. It's for anyone in emotional crisis, including the families of the missing.
You Are Not Alone
What you're doing right now is one of the hardest things a person can do. There is no perfect way to handle this, and there is no checklist that guarantees an outcome. What there is, is a community of people who have walked this road and who are here to help you walk it too.
If you need help at any point, reach out to us. Whether it's a question about next steps, a request to share your loved one's case, or just needing to talk to someone who understands, we're here.
