Assistant Escambia County Administrator Matt Coughlin turned in his 90-day notice of resignation yesterday, the fifth Escambia County senior official to resign in the wake of allegations of problems within the Department of Public Safety. In his resignation letter Coughlin said that in the County “…there is neither the ability or willingness to rise to the occasion and lead together,” and that “…those with the capability to help reverse this downward progression have resorted to tribalism…our mission has become a failure and our citizens have become the casualty.”
