One of two Dickson County Sheriff’s Office deputies injured in a Sept. 6 wreck that killed a Dickson man has already returned to duty while a second is expected back on the job within three weeks. Dickson Mayor Bob Rial said at Monday night’s county commission meeting the fact that deputies Sarah J. McCartney and Ronald W. Tilley were not more seriously injured is a testament to the safety of the new patrol cars bought last year. “The fact from when I was there that night and from what I gathered the next day from the state troopers, I don’t know that they thought they would survive in the other car,” Rial said. 47-year-old Tilley was driving car 525 that Friday night as the deputies were responding to a call with their lights and sirens activated. Around 7:30 on Highway 46 90-year-old Clyde Faling Jr. of Mt. Sinai Road apparently turned in front of the patrol car at the intersection with Barbecue Road. Faling died later that night from his injuries. Rial said the passenger cabin of the new patrol car remained virtually intact while most of the front end was demolished. He said the only intrusion into the passenger compartment was the heater fan blew out and struck McCartney in the legs. The deputy’s seat belt also triggered the tear gas canister on her belt, filling the inside of the car. Chief Deputy Jerone Holt said Monday that Tilley was already back at work and McCartney is expected back within 20 days. Rial said that might not have been the case had they been in one of the department’s older patrol cars. “It’s quite amazing. The state troopers said nobody should have walked away from this wreck,” Rial said. The sheriff’s office bought 16 new patrol cars last year and now has a rotation to replace eight cars every year.
