Dec. 5, 2017: Seattle Police Chief Kathleen O'Toole, who helped reform the department after federal officials found officers were too quick to use force against minorities, plans to retire at the end of 2017, Seattle Mayor Jenny Durkan said yesterday, Monday, Dec. 4, 2017. O'Toole took over as the Seattle Police Chief in 2014 as the city was struggling to carry out an agreement with the U.S. Department of Justice that was designed to decrease how often officers use force. New Seattle Mayor Durkan said Deputy Chief Carmen Best has been named to succeed O’Toole as the Acting Police Chief, effective on Jan. 1, 2018. Former Mayor Ed Murray hired O'Toole, a former Boston Police Commissioner. O’Toole was the first woman to run Seattle's Police Department. O'Toole, 63, joined the Boston Police Department as a Patrol Officer in 1979 and worked her way through the ranks. She was the Boston Police Commissioner from 2004 to 2006 before she completed a six-year term as the Chief of an oversight body responsible for reforms in the Irish national police force.
