Lieutenant Derrick Preston failed to address and document numerous complaints regarding Sergeant Kathryn Porter’s abusive behavior towards subordinates at the Manatee County jail. Despite being aware of the toxic environment created by Porter, Preston did not take appropriate disciplinary actions or document the complaints, effectively condoning the misconduct. An internal affairs investigation found that his negligence as a supervisor allowed Porter’s behavior to proliferate. As a result, Preston was demoted to first-class deputy, reassigned to courthouse security, and suspended without pay for one week. This case emphasized the critical importance of supervisory accountability in maintaining a professional work environment.
