SPARTANBURG COUNTY, S.C. (WSPA) -- Two sisters died Tuesday after getting into a car crash due to a non-functional traffic light. According to the Spartanburg County Coroner's Office, the crash occurred after 2 p.m. at the intersection of SC 9 (Boiling Springs Road) and California Avenue. Officials mentioned the traffic light at the intersection was down due to widespread power outages due to Tropical Storm Helene. The South Carolina Highway Patrol said that a Cadillac SUV was traveling north on SC 9 and approached the intersection, while a Toyota Camry was traveling west on California Avenue towards the same intersection. Both cars collided at the intersection according to troopers. All three occupants in the SUV were injured and taken to Spartanburg Regional Hospital. Their conditions are unknown at this time. One occupant in the Toyota died at the scene. The coroner's office identified the victim as 77-year-old Sarah Ann Farr, of Jonesville. 86-year-old Faye Farr Webber, of Jonesville, was also in the Toyota during the crash. She was taken to Spartanburg Regional, where she later succumbed to their injuries. The Spartanburg County Coroner's Office confirmed with 7NEWS that both victims were sisters. Their deaths are the eighth storm-related death to occur in the county after Helene. Officials mentioned that during this time, intersections can be deadly and should be treated as four-way stops until all lights and power can be restored. The crash remains under investigation by the SCHP.
