A Green Bay man will spend six and half years in prison for a crash that killed two of his family members on Christmas Day last year. That was the sentence to 39-year-old Philip Slezewski during his court appearance this (September 30th) afternoon. 38-year-old Heather Arcaro-Slezewski, who was Philip’s wife, and his mother 71-year-old Clarice Slezewski were killed in a two-vehicle crash after Philip, who was driving, rear-ended another SUV and caused both to spin out on I-43 last Christmas.
