Thirty years on the defense side of the courtroom.
Colleen Quinn Investigations is a Florida legal investigation and mitigation firm serving criminal defense attorneys in state and federal court, on capital and non-capital cases.

Colleen Quinn-Adams
A licensed investigator and mitigation specialist, Colleen has spent more than three decades helping defense attorneys present their clients in the context of their lives.
She has worked numerous high-profile state and federal cases, including capital prosecutions in which death was removed as an option, and her investigations have taken her across the United States and abroad, including Jamaica and Puerto Rico. In 2018 her investigation uncovered new evidence that led prosecutors to drop all charges against a man who had spent nearly three years in jail accused of a triple homicide.
Her experience extends well beyond capital cases, to homicide of every degree, manslaughter, serious felonies, federal white collar prosecutions including fraud, and matters involving negligence, serious injury and death.

Keeping people with mental illness out of the system.
Thousands of interviews have shown Colleen how often serious mental illness leads people into the criminal justice system. She helped develop the Forensic Behavioral Health Intervention Unit, a pilot program for the 13th Circuit Public Defender’s Office that diverts people with serious mental illness charged with minor offenses into community-based treatment and support.
A University of Tampa graduate and former scholarship recipient, she serves on the Dean’s Advisory Council of the Sykes College of Business, supports the university as a donor, and has spoken to its criminology students. For years she has also presented on the death penalty at a local high school.
