When someone cannot be located, families, lawyers, businesses, and organizations may need more than a basic online search. 3 Summit Investigations provides discreet missing person investigations in Calgary and surrounding areas using structured research, lead development, lawful investigative methods, and clear communication.

A structured approach to finding answers
Every case is different. We begin by reviewing the available facts, last confirmed contact, known risks, previous search efforts, and the reason the person needs to be located. From there, we identify realistic investigative options and develop a plan suited to the circumstances.
The process is evidence-driven. New information is compared against known facts so outdated, incomplete, or misleading leads can be separated from information that may actually help move the search forward.
Who may need a missing person investigation?
Private missing person investigations may support legitimate situations involving:
- Family members or loved ones who have lost contact
- Witnesses or other individuals needed for a legal matter
- Beneficiaries, former employees, tenants, or business contacts
- Cold leads where earlier attempts to locate someone were unsuccessful
- Cases requiring additional research alongside legal counsel or another authorized professional
Investigation methods may include
- Reviewing timelines, last-known locations, and communication history
- Open-source and public-record research
- Reviewing address history, business connections, employment information, and known associates
- Interviewing appropriate contacts and developing new leads
- Cross-referencing information to assess whether a lead appears current and credible
- Lawful field inquiries or surveillance when appropriate
- Organizing findings for the client or legal counsel
Information that can help
Useful details may include a full legal name, recent photograph, approximate age or date of birth, last known address, telephone numbers, email addresses, vehicle information, employment, social profiles, known associates, safety concerns, and a timeline of the last confirmed contact.
You do not need to have every detail before contacting us. Even partial information may provide a starting point, and we can explain what additional details could make the search more efficient.
What clients may receive
Depending on the assignment, clients may receive a summary of research completed, relevant leads, possible current location information, supporting details, and clearly stated limitations. Findings are organized so the client can understand what was discovered and decide on an appropriate next step.
Urgent safety concerns
If there is an immediate risk to life or safety, contact police or emergency services first. A private investigation does not replace an emergency response or an active police investigation. In some situations, a private investigator may be able to assist with additional lawful research after urgent safety steps have been taken.
Confidential and honest communication
Missing person matters can be deeply personal. We treat clients and the people involved with dignity and respect. No investigator can guarantee that every missing person will be located. Clients receive honest communication about scope, cost, progress, available options, and limitations.

If the goal is to identify a current address or contact information for a known individual, our Calgary skip tracing and address-locate services may be the most appropriate starting point. When a confirmed lead requires lawful observation or documentation, our surveillance services may also be relevant.
Missing person investigation FAQs
Can you guarantee that someone will be found?
No. The quality of available information, time since last contact, and circumstances of the case all affect the outcome. We provide realistic expectations and clearly explain the limitations of the search.
Should I contact police first?
If there is a safety concern, suspected crime, vulnerable person, or emergency, police or emergency services should be contacted first. A private investigation is not a substitute for emergency response.
