Missing Persons Investigations · Nationwide

When someone you love is missing, every hour matters.

Our licensed private investigators work alongside law enforcement, or independently when the case falls outside their priority, to locate missing family members, estranged relatives, runaways, and loved ones who have fallen out of contact.

Experienced, discreet, and persistent.

Missing persons cases are rarely simple. They can involve runaway teens, estranged adults who do not want to be found, elderly relatives with cognitive decline, long-lost family members, or someone who has deliberately cut contact. Our investigators bring decades of law enforcement and investigative experience to every case, with the discretion these sensitive matters require.

Estranged Family Members

Biological parents, adopted children, siblings who lost contact, or relatives separated by circumstance. We locate and verify current contact information so you can decide the next step on your own terms.

Missing Loved Ones

When someone stops returning calls, disappears after a crisis, or simply vanishes from their known routine, we conduct a thorough, professional investigation to confirm their well-being and location.

Runaways & At-Risk Youth

Time-sensitive investigations focused on locating runaway minors and at-risk young adults. We work closely with families and, when appropriate, coordinate with local authorities to bring them home safely.

Vulnerable Adults

Elderly relatives with dementia, individuals with mental health crises, or adults who may be under the influence of a coercive relationship. Our approach balances urgency with the care these cases demand.

Skip Tracing

Locating individuals who have moved without leaving a forwarding address, whether for inheritance notification, legal service, debt recovery, or reconnecting with family. Fast, accurate, and legally compliant.

Cold Cases

When a case has gone cold with law enforcement, a private investigator can review the record, develop new leads, and pursue angles that fall outside an overworked agency's capacity.

How a Missing Persons Investigation Works

Every case begins with a confidential conversation. From there, our approach is methodical, lawful, and always aligned with your goals.

1. Free Consultation

Tell us everything you know: last known location, relationships, habits, anything relevant. We outline what is possible, realistic timelines, and what information we need to start.

2. Records & OSINT

We exhaust public records, database searches, social media, and open-source intelligence to establish the subject's last verified presence and develop leads.

3. Field Investigation

When remote research reaches its limit, our investigators work the field, interviewing contacts, canvassing last known locations, and following leads in person.

4. Resolution & Report

You receive a clear written report of our findings. When the subject is an adult who does not wish to be contacted, we respect that boundary while confirming they are alive and safe.

Who We Help

Families, attorneys, adoption agencies, and individuals across the country trust Encyphir to bring clarity and resolution to the most difficult searches.

Families

Parents searching for an adult child who has cut contact. Siblings trying to reunite. Adoptees seeking biological family. Families quietly carrying questions for years; we help them get answers.

Attorneys & Estates

Heir searches, due-diligence locates, service of process, and witness location for active litigation. Our reports are court-ready and our chain of custody is legally defensible.

Law Enforcement Partners

We supplement, never replace, law enforcement. When an agency has exhausted its resources or the case falls below the threshold for active investigation, we pick up where they leave off.

Concerned Friends

Sometimes the person worried about the missing individual is not a legal next of kin. We work within what is lawful and appropriate to confirm a person's safety and well-being.

Cold Case Investigations

When a case has gone cold, when law enforcement has moved on and the trail has gone silent, a private investigator can pick up where the original investigation stopped. We review the case file, re-interview witnesses, apply modern forensic techniques to preserved evidence, and build a renewed, credible investigation package that gives families the best chance at answers they have had in years.

Case File & Evidence Review

A methodical, written assessment of the original investigation, covering what was done, what was missed, what physical evidence still exists, and which lines of inquiry remain workable today.

DNA & Genetic Genealogy

We coordinate with specialty forensic labs on modern DNA analysis and investigative genetic genealogy, the technique that has solved some of the most notorious cold cases of the past decade.

Witness Re-Interviews

People's circumstances change. Witnesses who were reluctant or uncooperative during the original investigation sometimes speak years later, and our investigators know how to approach them without creating legal exposure.

Unidentified Remains & John/Jane Doe Cases

We work missing persons cases alongside unidentified remains cases, including NamUs submissions, dental and medical record comparison, and family DNA reference coordination.

Wrongful Conviction Review

Post-conviction cold case work with defense counsel, innocence projects, and conviction integrity units. New DNA analysis, alternative suspect development, and disclosure review where the record supports it.

Support for Attorneys, Journalists & Families

Civil litigation support, documentary and journalism research support, and direct engagement with families, structured for whatever standard the work has to meet, from court-admissible to publication-ready.
