The Tennessee state medical examiner has ruled that carbon monoxide poisoning was the cause of death for Rosey Nix Adams and Jimmy Campbell. Adams, 45, the daughter of the late June Carter Cash and stepdaughter of the late Johnny Cash, and Campbell, 40, were found dead in a converted school bus on Oct. 24 near Clarksville, Tenn. Campbell was a well-known bluegrass fiddler, who had played with the late father of bluegrass, Bill Monroe. He had also been a regular with The Sidemen, the group that plays weekly shows at Nashville's Station Inn. He and Adams had been collaborating on recordings.
Propane heaters in the bus were the cause of the carbon monoxide poisoning, Dr. Bruce Levy ruled. Autopsies showed that Adams' blood contained a carbon monoxide level of 79 percent. Campbell's blood level was 74 percent. Although drug paraphernalia was found in the bus, Dr. Levy said that drug use did not appear to be a factor in the deaths. Levy's final report, including toxicology findings, is not expected to be complete for several weeks.
Funeral services are scheduled for Adams and Campbell on Wednesday (Oct. 29). Adams' service is set for 11 a.m. at the Hendersonville Funeral Home with burial at Hendersonville Memory Gardens. Campbell's service is set for 2 p.m. at Nashville's West Harpeth Funeral Home.
Adams was the daughter of Carter Cash and her second husband, Nashville police officer Edwin "Rip" Nix. Her siblings in the Carter-Cash family are Rosanne, Kathy, Cindy, Tara, John Carter and Carlene. Adams often sang with her mother and was a background vocalist on her 1999 album Press On.
