Kathleen M. O'Toole (née Horton; born May 9, 1954)[1] is an American law enforcement officer who served as Chief of the Seattle Police Department (SPD) from June 23, 2014, to January 4, 2018.

While maintaining her sworn State Police rank, she served from 1994 to 1998 as Massachusetts Secretary of Public Safety in the cabinet of Governor William Weld.

[5][6][7] While serving as Commissioner of the Boston Police, O'Toole was a central figure in the controversy surrounding the fatal shooting of Victoria Snelgrove during celebrations following the Boston Red Sox victory over the New York Yankees at Yankee Stadium in Game 7 the 2004 American League Championship Series.

During attempts to control the crowd that had gathered near Fenway Park, Boston police fired a "less lethal" FN 303 round, which missed its intended target and struck Snelgrove in the eye, resulting in her death approximately 12 hours later.
