A criminal defense private investigator supports attorneys by uncovering facts that strengthen a client’s case. They gather evidence, interview witnesses, review police reports, and analyze crime scenes to identify inconsistencies or overlooked details. Working closely with defense teams, they help build strategies that challenge the prosecution’s claims. Discretion, attention to detail, and strong research skills are essential. Their work can reveal new leads, support alibis, or expose procedural errors, ultimately contributing to a fair and thorough defense process for individuals facing criminal charges.
