Dedicated to Finding Answers When Someone Cannot Be Found

Few experiences are more frightening, frustrating, or emotionally devastating than not knowing where a loved one is or whether that person is safe.

A son or daughter suddenly disappears. A parent loses contact with an adult child. A relative vanishes without explanation. A longtime friend cannot be located. An elderly family member becomes unreachable. An individual disappears under circumstances that raise serious questions.

Whatever the circumstances, unanswered questions can leave families feeling helpless.

At Katz Investigations, we believe every missing person deserves to be taken seriously and every legitimate lead deserves careful consideration.

Established in 1988, Katz Investigations provides professional, confidential missing persons and location investigations throughout California and across the United States.

Our Missing Persons Special Unit focuses on developing leads, reconstructing timelines, identifying connections, conducting field investigations, and locating individuals whose whereabouts are unknown.

Under the direction of Paul Katz, a California Licensed Private Investigator and Certified Missing Persons Investigator (CMPI), we combine decades of investigative experience with research technology, investigative databases, public records, interviews, and traditional fieldwork.

We understand that a missing persons investigation is not simply another assignment. For a family searching for someone they love, the answers can mean everything.

Our Specialized Missing Persons Special Unit Investigative Services

1

Missing Adults and Family Members

We investigate cases involving adults who have disappeared, unexpectedly stopped communicating, or cannot be located through conventional means.

  • Locating missing adult sons, daughters, parents, siblings, and other relatives.
  • Investigating unexplained disappearances.
  • Reconstructing the individual's last known movements.
  • Identifying possible current residences and locations.
  • Researching associates, relatives, and former acquaintances.
  • Examining relevant address, employment, and public-record histories.
  • Conducting interviews with potential witnesses.
  • Developing and following new investigative leads.
  • Conducting lawful surveillance and field inquiries when appropriate.
  • Coordinating relevant information with law enforcement when authorized or warranted.

Every investigation is tailored to the circumstances, the available evidence, and the legitimate purpose of the search.

2

Missing Children and Vulnerable Individuals

Cases involving missing children, endangered individuals, or vulnerable adults require particular care and urgency. Katz Investigations may assist families and their attorneys with supplemental investigative research and lead development, where legally appropriate.

  • Reviewing known circumstances and researching relevant connections.
  • Interviewing witnesses and examining available records.
  • Organizing information that may assist law enforcement.

We do not replace law enforcement, and we do not undertake unauthorized child recovery operations. Cases involving missing minors, immediate danger, or suspected criminal conduct must be reported to the appropriate authorities.

3

Long-Lost Family Members and Family Reunification

Not every missing person has disappeared under suspicious circumstances. Sometimes families lose contact because of relocation, divorce, adoption, family disagreements, name changes, or simply the passage of time.

  • Locating estranged parents or adult children.
  • Finding siblings separated for many years.
  • Searching for birth relatives and biological family connections.
  • Locating family members after decades without contact.
  • Researching former names, marriages, and address histories.
  • Finding relatives who moved to another state.
  • Locating individuals whose last known information is many years old.

When a person is located, we respect that person's legal rights and privacy. Where appropriate, we can facilitate a request for voluntary contact without disclosing a private residential address.

4

Suspicious Disappearances and Unexplained Circumstances

Some disappearances involve conflicting statements, unexplained behavior, questionable relationships, or circumstances that suggest further investigation may be necessary.

  • Developing a detailed chronology of events.
  • Identifying the last independently confirmed sighting.
  • Reviewing inconsistencies in statements.
  • Interviewing witnesses and other potential sources.
  • Researching relevant relationships and associations.
  • Examining lawfully available records and digital information.
  • Identifying potential surveillance footage and witnesses.
  • Documenting new information for appropriate authorities.

Our role is to gather facts objectively, not to presume that a crime occurred.

5

Cold Cases and Long-Term Missing Persons Special Unit

Some missing persons cases remain unresolved for months, years, or even decades. Katz Investigations can independently review older cases to identify investigative opportunities that may have been overlooked or were previously unavailable.

  • Original timelines and prior investigative findings.
  • Historical addresses and former associates.
  • Public records created after the disappearance.
  • Changes in names, residences, or business affiliations.
  • Previously unidentified witnesses.
  • Relevant court, property, and administrative records.
  • New information developed through contemporary investigative research.

We cannot guarantee that an older case will be solved, but we can evaluate whether additional investigative avenues remain available.

6

Missing Elderly Persons and Welfare Concerns

An elderly individual who suddenly becomes unreachable may present an especially serious concern. Families may be worried about declining health, isolation, exploitation, hospitalization, or a sudden change in living circumstances.

  • Researching last known residences.
  • Identifying potentially relevant relatives or caregivers.
  • Conducting appropriate in-person location inquiries.
  • Checking available public information.
  • Developing information regarding possible relocation.
  • Assisting authorized family members and attorneys with appropriate inquiries.
  • Recommending law enforcement or adult protective services involvement when necessary.

We approach these cases with discretion, sensitivity, and respect for the individual's autonomy.

7

Difficult-to-Locate Individuals and Skip Tracing

Attorneys, businesses, estate representatives, and private clients frequently need to locate individuals who have moved, disappeared from public view, or left little current contact information.

  • Locating missing heirs and estate beneficiaries.
  • Finding witnesses needed for litigation.
  • Locating individuals for legitimate legal proceedings.
  • Identifying current or recent addresses.
  • Researching former addresses and known associates.
  • Identifying relevant business and professional affiliations.
  • Conducting nationwide skip-tracing investigations.
  • Verifying investigative leads through independent research and fieldwork.

For particularly difficult cases, multiple investigative methods may be combined to improve the reliability of the findings.

Our Investigative Methods: How We Search for Missing Persons Special Unit

A professional missing persons investigation requires more than entering someone's name into an internet search engine. At Katz Investigations, we take a systematic, evidence-based approach.

Comprehensive Database and Public Records Research

Our investigators use legally available investigative resources to develop information about a person's possible whereabouts. These records may provide important clues, but database information can be incomplete, outdated, or inaccurate. Significant findings are evaluated and corroborated whenever reasonably possible.

Social Media and Open-Source Intelligence

A person's publicly available digital history may reveal connections, activities, and possible locations. We use lawful open-source research methods and do not obtain unauthorized access to private accounts, communications, or devices.

Interviews and Witness Development

Traditional investigative interviewing remains one of the most valuable investigative techniques. A missing person may have spoken with a friend, former coworker, neighbor, relative, or other acquaintance before disappearing. Our investigators may conduct interviews to identify new leads, confirm relevant events, resolve conflicting information, and develop a clearer understanding of the person's circumstances.

Field Investigations and Location Verification

When database research is insufficient, physical investigation may become necessary. Our investigators may visit last known addresses, examine relevant neighborhoods, contact appropriate sources, and conduct lawful observational surveillance.

Timeline Reconstruction and Lead Analysis

In cases involving unexplained disappearances, we work to establish what is known, what remains uncertain, and which leads may deserve priority. A detailed chronology can help identify inconsistencies, missing information, and significant changes in a person's activities before contact was lost. Our investigators distinguish verified facts from unconfirmed statements and investigative possibilities.

Frequently Asked Questions

Can a private investigator find someone the police have not located?

A private investigator may develop independent leads, conduct additional research, or focus resources on avenues that have not been fully explored. Results depend on the circumstances and available evidence. We do not guarantee that a missing person will be found.

Do I have to wait 24 or 48 hours before reporting someone missing?

No. If you believe someone is missing and may be endangered, contact law enforcement promptly. There is no universal 24- or 48-hour waiting requirement before making a missing person report.

Can you investigate a disappearance that occurred years ago?

Yes. We can assess long-term missing persons cases and determine whether additional investigative opportunities exist.

Can you locate someone anywhere in the United States?

Katz Investigations accepts appropriate nationwide location assignments, using lawful research resources and field assistance as necessary.

Can you locate someone who changed their name?

Potentially. Relevant historical records, lawful identity research, and associated information may help establish connections between former and current identities.

Can you guarantee that I will receive someone's address?

No. Locating an individual does not necessarily authorize disclosure of that person's private location. We evaluate each assignment for lawful purpose, safety, privacy, and appropriate handling of the findings.

What does a missing persons investigation cost?

Fees depend on the complexity of the case, the information available, the amount of research required, and whether field investigations or travel are necessary. We discuss the proposed scope and anticipated charges before beginning an assignment.

Will my investigation remain confidential?

We treat inquiries and investigative information discreetly, subject to applicable law, safety requirements, and necessary disclosures.

Don't Let an Important Lead Go Unexplored

You may have already searched online, contacted relatives, called former addresses, or exhausted the obvious options. Professional investigative assistance may help identify additional avenues worth pursuing.

At Katz Investigations, our mission is to pursue legitimate leads, uncover reliable information, and help our clients find answers through thorough, lawful, and professional investigation.

Whether you are searching for a missing loved one, a long-lost relative, a missing heir, or an individual whose whereabouts remain unknown, contact our Missing Persons Special Unit to discuss your case.
