BATON ROUGE, La. — Baton Rouge’s police chief is retiring after nearly four years in the position.

Mayor-President Sharon Weston Broome said in a statement Monday that the city will conduct a national search for Police Chief Carl Dabadie’s permanent replacement.

Dabadie’s last day of service is Oct. 2. Broome has appointed Lt. Jonny Dunnam to serve as interim chief.

During her mayoral campaign last year, Broome had said she would replace Dabadie as chief.

Dabadie led the department through a tumultuous summer last year. A gunman ambushed and killed three law enforcement officers in Louisiana’s capital city less than two weeks after a white Baton Rouge police officer fatally shot a black man during a struggle outside a convenience store last July.
