Investigative Services
Nine disciplines. One case team.
Most investigations don't stall for lack of effort. They stall because one perspective ran out of road. Every IRIS engagement can draw on all nine.

Each discipline is led by a specialist who spent a career practicing it. Follow any of them for detail on scope, method, and the people involved.

Most cases don't need a bigger PI firm. They need a different kind of team.
A typical private investigation firm
- One investigator, or a small generalist staff
- Built for surveillance, records checks, and domestic cases
- Forensic work sent out — or not done at all
- Limited exposure to homicide and missing persons casework
The IRIS case team
- Ten specialists available to a single case
- Led by a 34-year major crimes detective
- DNA, behavioral, geographic, digital, and tracking expertise in-house
- Careers spent leading homicide, cold case, and missing persons investigations

Two more things we're regularly asked for
On-site incident response
Rapid deployment to an active scene or search, bringing evidence-search discipline and command experience to an incident while it is still unfolding.
Background investigations
Thorough, documented background work for employers, counsel, and private clients who need more than an instant database report.
