 A state trooper accused of manslaughter and the death of an Owatonna teen has chosen an experienced attorney to represent him in court. Eric Nelson filed documents to become Shane Roper's attorney in Olmstead County District Court last week. Nelson previously represented Minneapolis police officer Derek Chauvin, who was found guilty of murder and manslaughter and the death of George Floyd. Roper is facing nine charges following a May crash in Rochester that killed 18-year-old Olivia Flores and injured several others.
