Fresno Police Chief Paco Balderrama resigned following an investigation into an affair with the wife of a subordinate officer. Despite findings that he did not abuse his power, the investigation revealed poor discretion, making it difficult for him to maintain trust within the department. Deputy Chief Mindy Casto will serve as interim chief while a national search for a new chief is conducted. Mayor Jerry Dyer expressed disappointment but acknowledged Balderrama's accomplishments, including reductions in violent crime and increased officer recruitment. The investigation and subsequent resignation have brought intense media scrutiny and raised questions about the investigation's transparency.
