At NBI, we know that trust matters. Hearing from real clients helps you understand the level of care, professionalism, and dedication we bring to every investigation—whether for individuals or attorneys.
I can attest to Mr. Ruff’s honesty, integrity and competence as an investigator. He is a person of strong moral character who approaches sensitive matters with care and discretion, earning the trust of attorneys, clients and experts alike. He skillfully reviews legal records, develops leads, interviews witnesses, analyzes forensic evidence and uncovers material facts that have meaningfully advanced the pursuit of justice.

As a retired Supervisory Special Agent with the FBI and former member of the Behavioral Analysis Unit, I have spent my career evaluating the integrity, skill, and instincts of investigators. I can say without hesitation that Bob possesses the core qualities essential to this work; tenacity, sound judgment, ethical clarity, and the ability to uncover facts where others might only see dead ends. In every case we’ve collaborated on, from complex criminal case reviews to behavioral assessments, Bob has demonstrated exceptional skill in locating hard-to-find information, interviewing witnesses with care and precision and drawing informed conclusions grounded in evidence.

If it weren’t for Bob Ruff, without question I would be spending the rest of my life in prison for a crime I didn’t commit. He put everything he had into investigating my case. Bob proved to the world I’m innocent. He gave me my life back.

Murder 1998 – Freed in 2018
My work entails re-investigating homicide cases, often in partnership with The Innocence Project, that are often decades old in order to reopen my clients’ cases in court. These investigations require the expertise and insight of an experienced and astute investigator. I have worked with many professional investigators over the years, and can say without any hesitation that Bob Ruff is no less than the best of them. His instincts are uncanny and his skills, integrity and diligence contribute to how successful he is in his investigations.
