It's been a tragic winter on the ice across Minnesota, according to the Department of Natural Resources. So far five people have died after falling thru the ice, with a sixth person missing and presumed drowned.

DNR boat and water safety specialist Kara Owens says this winter is on track to be the deadliest on the ice in Minnesota in six years.

DNR officials say the minimum thickness for walking on ice is four inches, for a snowmobile or ATV it's at least five inches, and it's 8-12 inches for a car and more than 12 inches for a medium-sized truck.
