The North Carolina county that is home to Asheville overcounted deaths caused by Helene by as many as 30, according to a statement Tuesday from its sheriff’s office and data from the state, significantly reducing the death toll from the historic storm.

Buncombe County officials, who previously reported 72 deaths, are now deferring to a state tally of 42 deaths for the county.

The county’s number dates back to an Oct. 3 news release in which county officials reported that “72 lives have been lost due to Hurricane Helene,” repeating a number cited by Sheriff Quentin Miller at an earlier media briefing. But state officials, relying on reviews by the Office of the Chief Medical Examiner in Raleigh, have consistently reported a number lower than that for the county. The number for Buncombe County included in the state’s tally has stood at 42 since at least Oct. 10.

On Tuesday, the Buncombe County Sheriff’s office acknowledged in a statement that the number of deaths in the county was lower than the number it provided.

“In the early aftermath of Hurricane Helene, all deaths were being classified as storm related and from Buncombe County. However, as the days progressed, BCSO was able to identify who had passed away due to the hurricane, who was in fact from Buncombe County, and who passed away from other causes,” Buncombe County Sheriff’s Office Public Information Officer Christina Esmay told CBS News in a statement Tuesday. “Compounded with the lack of consistent communication, due to widespread outages, the Buncombe County fatality number that was initially provided to Sheriff Miller has decreased.”

The sheriff’s office did not provide additional information.

The Office of Chief Medical Examiner in Raleigh typically reviews weather deaths and makes a ruling on cause before reporting numbers through state officials, a process it has used in past storms for years. But in the chaos following Helene, a number of counties reported fatality numbers independently of the state. The state’s tally has gradually increased through Tuesday, but the climb has slowed as bodies have been examined.

A spokesperson from the North Carolina Department of Health and Human Services told CBS News that Buncombe County is “relying on the state to report storm-related deaths.” Hannah Jones, the spokesperson, said the state’s count of storm-related fatalities stands at 96, with 42 of these deaths were in Buncombe County.

“We do not have information about how Buncombe County was determining fatality numbers for the death totals they were reporting for their county. We understand that Buncombe County decided to stop their independent reporting a couple weeks ago and are relying on the state to report storm-related deaths,” Jones said.  

Another county, Henderson, had previously reported two more deaths than the state, but said on Tuesday that it agrees with the state’s tally of 7 deaths.

Using the new North Carolina figures, CBS News has now confirmed through Tuesday at least 215 total deaths across multiple states due to Helene.
