Fire deaths in Minnesota last year were the second lowest they’ve been since the state began compiling those statistics in 1970. That’s according to the preliminary numbers out today from the Department of Public Safety. 36 people died in fires in 2016–a 37-percent decrease over 2015. The leading causes of fatal fires last year was careless smoking, followed by combustibles too close and suicide or arson. State Fire Marshal Bruce West says it’s difficult to pinpoint a reason for last year’s decrease–but he’s reminding Minnesotans to take fire prevention in their homes more seriously.
