 Olmstead County Attorney Mark Ostrom says his office has charged Trooper Shane Roper with second-degree manslaughter, criminal vehicular homicide, and other counts stemming from the May 18 crash that killed 18-year-old Olivia Flores. Roper was allegedly traveling 83 miles an hour in a 40-mile-an-hour zone. He also did not have his emergency lights or siren activated before hitting a car that was making a left turn.
