(EMMETT TOWNSHIP) -- A 54-year old Armada man was killed in a single-vehicle crash early Tuesday morning in Emmett Township. St. Clair County Sheriff Tim Donnellon says the man was traveling south on Carney Road at around 12:30 a.m., when his pickup crossed the centerline, left the roadway, and struck a tree. The pickup continued down the ditch line, re-entered the road, and flipped upside down. The Armada man was ejected from the pickup and pronounced dead at the scene. Sheriff's deputies say alcohol is not believed to be a factor in the crash, which remains under investigation.
