A Storm Lake woman was killed and two others injured following a three-vehicle crash Thursday morning in Cherokee County. According to the Iowa State Patrol, the accident occurred at approximately 10:18 a.m. on County Road C63 south of Cherokee. Authorities say a 2018 GMC Terrain, driven by 76-year-old Denise Betts of Alta, was traveling westbound on C63 and rear-ended a county-owned road grader, operated by 46-year-old Kelly Ebel of Cherokee. A Victory motorcycle, driven by 74-year-old Everett Paeper of Aurelia, then collided with the Betts vehicle. A passenger in the Terrain, identified as 97-year-old Naomi Benna of Storm Lake, sustained life-threatening injuries and was transported to Cherokee Regional Medical Center by Cherokee County Emergency Medical Services. She was later pronounced dead at the hospital. Betts and Paeper were both also transported for treatment with serious injuries. The Cherokee County Sheriff’s Office and Aurelia Fire and Police Departments also assisted at the scene.
