Legal Investigation & Mitigation

Every client has a story the court has not heard yet.

For more than 30 years, Colleen Quinn Investigations has given criminal defense attorneys the investigation, mitigation and sentencing advocacy that move outcomes in state and federal court.

The CQI difference

Built to work inside the defense team.

Attorneys keep coming back for the same reasons: the work is thorough, it arrives on time, and it is ready to use in court without being rebuilt.

Engaged through counsel

We work as an agent of the defense attorney, so our work product stays within the defense team. We are available on private retention and on appointed state and federal cases.

Everything in one usable record

Interviews, records and history come back as a single organized report with every source cited, ready for a sentencing memorandum, a mitigation hearing or a penalty phase.

Proven on the hardest cases

Our team has worked capital cases in state and federal court, including federal prosecutions in which the government withdrew the death penalty.

Selected results

Outcomes our work has contributed to.

State of Florida

All charges dropped

A client facing the death penalty for a triple homicide was released after the defense investigation uncovered phone and location evidence, new witnesses and video. The State entered a nolle prosequi.

United States District Court

Death penalty withdrawn

Across several federal capital prosecutions, including racketeering and murder for hire cases, death was removed as an option after mitigation was presented to the Department of Justice.

State and federal

Reduced sentences

In non-capital cases, our mitigation reports and sentencing videos give the court the full picture of the person being sentenced, not only the offense.

New service

Sentencing advocacy for professionals and public figures.

Not every client’s story is one of hardship. For executives, licensed professionals and athletes, the strongest sentencing case is often a record of contribution: community work, careers, families who depend on them, restitution already underway and programs already started. We document that record and build it into a sentencing portfolio for counsel.
