When a loved one goes missing, or a critical witness vanishes before a trial, the world seems to stop. The minutes feel like hours, and the uncertainty can be overwhelming. In these high-stakes moments, many people turn to a private investigator to bridge the gap between official reports and the boots-on-the-ground work required to find answers.
At Armstrong Investigations, PLLC, we understand that time is of the essence. We serve clients across the Dallas-Fort Worth Metroplex, North Texas, and surrounding counties, and we know that missing person cases often require local familiarity as much as investigative skill. Finding the right missing persons investigator isn’t just about hiring someone with a badge; it’s about finding a professional who understands the legal landscape, the digital trail, and the human element of every case.
If you are currently searching for help in DFW or the surrounding North Texas area, here are 10 essential things you should know about hiring a missing persons investigator.
1. We Complement Official Efforts
One of the most common misconceptions is that you have to choose between the police and a private investigator. In reality, we work best when we complement official efforts. While law enforcement agencies are often stretched thin by heavy caseloads and administrative red tape, a private investigator can provide dedicated, 24/7 focus on your specific case. We don't replace the police; we act as a force multiplier, following up on leads that might not meet the threshold for immediate official action but are vital to finding your person.
2. The Power of a Legal Background
Not every missing persons investigator brings a legal education to the table. At Armstrong Investigations, PLLC, our founder, Jasen A. Armstrong, holds a J.D. (Juris Doctor) and graduated law school in 2015. Since his graduation, he has worked specifically with attorneys and is very well-versed in the law. That legal background helps guide our approach to the rules of evidence, the nuances of privacy law, and how to gather information that is actually useful if the case eventually moves into a courtroom. This foundation helps ensure that our findings are credible and that our methods are always above board.

3. Skip Tracing is an Art and a Science
You may have heard the term skip tracing in movies or debt collection contexts, but in missing persons work, it is a sophisticated process of "tracking a skip." This involves more than just a quick Google search. We utilize high-level commercial databases, proprietary software, and deep-web searches to find current addresses, utility records, and updated contact information. Skip tracing is often the first step in narrowing down a person's location when they have intentionally or unintentionally disappeared.
4. Digital Tracking: The Modern Trail
In today’s world, everyone leaves a digital footprint. An expert missing persons investigator uses Open-Source Intelligence (OSINT) to analyze social media activity, forum posts, and digital check-ins. We look for patterns in online behavior that might indicate where a person is or who they are with. Digital tracking allows us to see connections that aren't visible on the surface, helping us piece together a person’s movements in the days or hours leading up to their disappearance.

5. Surveillance Services Provide Real-Time Verification
Once we have a lead on a location through skip tracing or digital tracking, surveillance services become critical. It isn't enough to know where someone might be; we need to verify where they are. Professional surveillance requires patience, discretion, and high-quality equipment. Whether it's verifying a sighting or monitoring a location where a missing person is suspected to be staying, our surveillance team provides the visual proof needed to move a case forward across the Dallas-Fort Worth Metroplex and surrounding North Texas communities.
6. Proactive Pursuit in High-Stakes Cases
At Armstrong Investigations, PLLC, we specialize in what we call "Proactive Pursuit." This is especially relevant in high-stakes cases involving at-risk individuals, runaway teens, or witnesses in significant legal matters. We don't wait for information to come to us; we go out and find it. This proactive approach involves knocking on doors, interviewing neighbors, and canvassing areas where the person was last seen, whether that is in Dallas, Fort Worth, Collin County, Denton County, or another nearby county in North Texas. In a missing person case, being proactive often makes the difference between a cold lead and a successful recovery.
7. Welfare Checks are a Priority
Sometimes, you just need to know that someone is safe. We are frequently hired to perform welfare checks on individuals who have stopped responding to family members or who may be in a vulnerable situation. For families in the Dallas-Fort Worth Metroplex, that can mean quick deployment in areas like Dallas, Tarrant, Collin, Denton, Rockwall, Ellis, Johnson, Kaufman, Parker, Wise, Hunt, Navarro, Henderson, Hood, Somervell, Erath, or Palo Pinto counties when time matters most. Unlike official welfare checks that may be brief, we provide a detailed report of the individual's surroundings and well-being, giving families the peace of mind they need or the evidence required to take further legal action.

8. Ethics and Confidentiality are Non-Negotiable
When you hire a private investigator, you are sharing some of the most sensitive details of your life. You need to know that your information: and the information of the person being sought: is handled with the utmost discretion. Armstrong Investigations, PLLC operates with a strict code of ethics. We ensure that our investigative methods protect the privacy of our clients while strictly adhering to Texas law.
9. Understanding the Cost and Scope
Investigation work is labor-intensive and requires specialized tools. Before hiring an investigator, it’s important to have a clear understanding of the fee structure. Whether it’s an hourly rate for surveillance or a flat fee for specific skip tracing services, transparency is key. We pride ourselves on being clear about what can realistically be achieved within a set timeframe and budget, ensuring there are no surprises during an already stressful time.
10. The Importance of Professional Affiliations
A reputable missing persons investigator should be properly licensed and connected to the professional community. Armstrong Investigations, PLLC is a Texas-licensed firm, and our affiliations: including TCS Consulting and Howard Law, PLLC: provide us with a broad network of resources. These connections allow us to leverage expertise across different sectors, from technical security to legal strategy, providing a comprehensive approach to every missing person case.
