(Green Lake County) A Berlin man was killed following a single-vehicle crash early Thursday morning in Green Lake County. The accident occurred at 12:15am on the 100 block of West Ceresco Street in the city of Berlin. When officers arrived on scene, they found the driver and lone occupant trapped inside his pickup. The 32-year-old apparently struck the side of a building and then a retaining wall before coming to rest. The officer was able to remove the victim but was unsuccessful in rendering first aid and CPR and he was pronounced dead at the scene by the county coroner. Chief Dennis Plantz says alcohol and high speed are potential causes. It was the second fatal crash in Green Lake County since 2016 with the most recent occurring just ten days earlier.
