This is an increase of 16 percent when compared with the 45 officers who were accidentally killed in 2015. By region, 24 officers died from accidents in the South, 12 in the Midwest, nine in the West, five in the Northeast, and two in Puerto Rico.
Twenty-six of the officers died as a result of automobile accidents, 12 were struck by vehicles, and seven were fatally injured in motorcycle accidents. Three officers died in accidental shootings, two victim officers drowned, one died in an aircraft accident, and one victim officer was fatally injured when thrown from a horse.
