A 46-year-old man from Chisago City was sentenced today to 12-and-a-half years in prison in connection with the drunken snowmobile crash that killed an eight 8-year-old boy on Chisago Lake in early 2018. Eric Coleman was convicted in December of third-degree murder in the crash that killed 8-year-old Alan Geisenkoetter Jr. as the boy set up a fish house on the frozen lake with his family.
