Colonel Heston Silbert, the director of the Department of Public Safety, will serve as interim director for the time being, he said.
It is unclear why they both resigned. Ducey s office didn t send out a press release regarding the turnover and Karamargin wouldn t comment further on the matter, stating, We do not talk about personnel matters.
Rosenberger and Cocca did not respond to requests for comment. Jeffrey Trillo, the agency s assistant director, also did not respond to requests for comment.
Cocca served as director of the agency since 2015 after a long stint as an assistant chief in the Scottsdale Police Department, according to his LinkedIn profile.
