The probe into the August crash that killed U.S. Rep. Jackie Walorski, R-Ind., and three others faulted the driver of the SUV she was riding in for trying to make an unsafe pass. Potts had slowed to create distance with the flat-bed, then accelerated to 82 mph to make the pass, sheriff's investigators said in a statement. "The Toyota was then observed accelerating to a high rate of speed, closing the distance to the unidentified truck," the sheriff's office said. There was no evidence that phones were being used prior to or during the crash, and there was no indication of mechanical failures, the sheriff's office said. Indiana Republicans picked Rudy Yakym, an executive with Elkhart distribution company Kem Krest, to replace Walorski on the ballot.
