(Portland, OR) -- Three Multnomah County Corrections deputies are under investigation for allegations of misconduct. Mirzet Sacirovic, Jorge Troudt and Gustavo Valdonsinos were accused of allowing assaults, providing contraband, and access to computers and cell phones between 2018 and 2020. The District Attorney's Office declined to file criminal charges based on the evidence and credibility of defendants. Sheriff Morrisey O'Donnell has launched a professional standards investigation. It'll be led by an independent investigator. Several changes were made at the jail to help prevent similar future incidents. The deputies remain on leave during the investigation.
