An 18-year-old was critically injured after falling about 20 stories inside the decommissioned Checkerboard Grain Elevator in Minneapolis. Police said the teen was trespassing with a group when he fell onto an elevated platform. Firefighters used a ladder truck to reach him before he was taken to Hennepin Healthcare with life-threatening injuries. Authorities called his survival a miracle and are warning young people about the dangers of entering abandoned properties. Neighbors say they had repeatedly reported concerns about trespassing at the site. #Minneapolis #PublicSafety #UrbanExploring #MinnesotaNews #FOX9
