VERIFYE® CREDIBILITY ASSESSMENT

The Tool That Speaks Before Your Client Does

At sentencing, the judge hears your argument and reads the probation officer's PSI. A VerifEye® report adds a tested answer to a specific question, such as whether your client's account of the offense is truthful.

Why Attorneys Order This

Judges consider acceptance of responsibility at sentencing, but what they usually have to go on is your argument and the probation officer's PSI.

VerifEye® is an ocular-motor credibility test developed by Converus. It measures involuntary eye behavior while your client answers specific questions by video. The result is a signed report from a Converus-certified examiner you can offer alongside the PSI.

What it is not: results are generally not admitted as trial evidence in Texas, and the test does not measure remorse, character, or future risk. We tell you that up front so the report is never oversold in court.

Pre-sentencing: Know how your client's account tests before you rely on it in court
Sentencing mitigation: Offer a tested result with your mitigation materials; the judge decides its weight
Out-of-county clients: 100% remote — no travel, no scheduling headaches
Converus-certified examiner administers and signs every report
Results delivered to iai.veripsi@outlook.com within 48 hours of session

🔎
Witness Location & Interview
We locate and interview witnesses law enforcement may have missed, ignored, or discouraged — building the alternative narrative your client deserves.

Every agency has written SOPs. We compare what officers did against what their own policies required — and document every deviation with command-level authority.

CREDIBILITY ASSESSMENT

EyeDetect® — A Digitally Scored Alternative to Polygraph

Developed by Converus. Non-invasive, no physical contact, digitally scored.

The EyeDetect® Advantage
EyeDetect measures involuntary eye behavior — pupil dilation, blink rate, and reading patterns. Unlike polygraph, it requires no physical attachment and produces a digitally scored result. Dr. Walwyn administers EyeDetect in person on a computer-based station; remote testing is available through VerifEye.
