Investigation meets legal strategy
Most investigators gather information. We build evidence. There’s a meaningful difference—and it shows in the outcome.
Armstrong Investigations, PLLC was founded on a straightforward premise: an investigation is only as valuable as its admissibility. Jasen A. Armstrong, J.D. bridges the gap between raw field intelligence and high-level legal strategy, ensuring that what we document is gathered correctly, preserved properly, and presented in a way that survives adversarial scrutiny.
Through our affiliation with Michael Depew of TCS Consulting, we extend our capabilities into technical domains that most investigative firms simply can’t touch—accident reconstruction, EDR data extraction, and advanced digital forensics.

Fugitive Recovery Services: Locate, Apprehend, Return
When a defendant skips bail, Armstrong Investigations locates and brings them back. We serve both licensed bail bondsmen operating under active warrants and private individuals who need a fugitive located and lawfully returned through proper authority. Using skip tracing, surveillance, and digital intelligence, we develop a confirmed location — then execute a fugitive recovery and lawful apprehension.
What Separates Us From Every Other Firm In The Room
Most investigative firms collect information. We build evidence—and there’s a meaningful difference when the stakes involve a courtroom, a custody hearing, or a multi-million dollar claim.

"The Investigator I Trust With My Clients"
“In the realm of managing sensitive family law cases, it is crucial to have someone who comprehends the stakes involved. Jasen not only conducts surveillance but also fully understands the objectives and rationale behind our efforts. He is discreet, efficient, and has never placed me in a situation where I had to present unfavorable evidence to a judge. This peace of mind is invaluable.”"Evidence That Actually Holds Up"
"I've worked with a lot of investigators over the years, and the difference with Armstrong is the chain of custody. When Jasen hands over a file, I don't have to spend hours vetting whether the evidence will survive a motion to suppress. It's courtroom-ready from the moment it hits my desk. That's rare, and it's why I keep coming back.""The Only Investigator I Brief Like a Co-Counsel"
"Most investigators need the full picture explained twice. With Jasen, I give the case theory once and he builds around it. He understands what I need before trial, what I can't afford to have excluded, and what documentation a judge will actually credit. That level of legal fluency from an investigator is genuinely hard to find — and once you work with someone who has it, you stop accepting anything less."
"Surveillance I Can Actually Put In Front of a Jury"
"I retained Armstrong Investigations on a contested workers' compensation case where everything hinged on what the claimant could and couldn't do. The video Jasen delivered was clear, timestamped, continuous, and completely unimpeachable. No gaps, no angles that opposing counsel could argue away. The case resolved at mediation the week after I sent the footage to the other side. That's the standard I expect now."
"Finally Answered Questions We'd Carried for Years"
"My family had lived with uncertainty about my brother's death for almost four years. The official finding never sat right with us, but we didn't know where to turn. Armstrong Investigations treated the case with the same rigor they'd apply to any active investigation — no shortcuts, no assumptions. What they uncovered didn't just give us answers. It gave us the documentation to pursue what comes next. I can't put a value on that."
"Brought Precision to a Case That Needed It Most"
"We had a multi-vehicle commercial accident case where the liability question came down to EDR data. Jasen brought in TCS Consulting and the technical depth they delivered — timeline reconstruction, speed data, brake engagement — was the kind of expert analysis that wins cases before they reach a jury. The opposing carrier settled within 60 days of receiving the report. That's not a coincidence."
What Our Clients Say
When the stakes are high, the investigator you choose makes all the difference. These are the people who trusted Armstrong Investigations when it mattered most.
