      The Cheyenne County Attorney’s Office says speed appears to have been a factor in a one-vehicle accident early Wednesday morning in Sidney that killed a local man.Â
        37-year-old Shane Marron was alone, driving an SUV at a high rate of speed on a road near Cabela’s former headquarters when it went off the pavement.
He overcorrected and the SUV flipped end-over-end.Â
Investigators say Marron was not wearing a seat belt and was ejected. He was pronounced dead at the scene.
