Proactive Pursuit — Because Every Hour Counts
Our Missing Persons & Locate Services
Missing Persons Investigations
We conduct active, methodical searches for individuals who have gone missing under any circumstances — voluntary departure, runaway situations, at-risk adults, or cases where the circumstances of the disappearance are themselves unclear. Our approach combines digital intelligence, skip-tracing tools, surveillance, and ground-level fieldwork in an integrated strategy designed to produce current, actionable location information as quickly as possible.
Skip Tracing & Professional Locates
Professional skip tracing uses a combination of high-level commercial database access, utility and address records, social network analysis, and cross-referencing of partial information to develop a working location hypothesis. We find people who have left a known location — whether voluntarily or not — and verify their current whereabouts through surveillance before the locate is considered confirmed.
Witness & Party Locates for Legal Proceedings
A witness who cannot be found is a witness whose testimony cannot be used. Attorneys across the DFW Metroplex rely on us to locate witnesses, parties to litigation, and individuals required for service of process — with the urgency that legal deadlines demand. We provide both the locate and the service, in a single coordinated engagement.
Digital Tracking & OSINT Intelligence
Social media activity, device location data, digital check-ins, online purchasing patterns, and communication metadata all leave trails that experienced investigators know how to read. Open-source intelligence techniques allow us to reconstruct movements and connections in the period before and after a disappearance — surfacing leads that physical canvassing alone would take days to develop.
Welfare Checks
When a family member has stopped making contact, a vulnerable adult's circumstances are unclear, or someone's behavior has raised concern without a clear crisis, a professional welfare check provides documented, objective confirmation of a person's condition. Unlike a neighbor's knock or a phone call, our welfare checks produce a verified record of the person's status, location, and circumstances at the time of contact.
Drone Search Support
For hard-to-access terrain, large outdoor areas, or searches requiring rapid coverage of ground that foot teams cannot cover efficiently, we deploy drone assets equipped with high-definition and thermal imaging. Thermal imaging is particularly effective in searches conducted after dark or in conditions where visual identification of a subject through standard optics is not practical.
No Jurisdictional Boundaries. No Waiting.
Official missing persons resources operate within jurisdictional limits, prioritization protocols, and workload constraints that private investigation is not bound by. An active missing persons case may receive immediate attention from law enforcement and then cycle into a slower administrative track as other calls come in and urgency fades.
A private investigator operates on your timeline, working the leads that are active now, with the flexibility to follow the case wherever it goes — across county lines, across state lines, or across whatever digital landscape the subject has left a trail through.
Armstrong Investigations does not wait for official processes to stall before getting involved. We can work alongside law enforcement from the start, pursue leads independently, and deliver current intelligence that advances the search in ways that passive monitoring never can.
For families who have already been through the official process and still don’t have answers — we take those cases too.
