WSB-TV reported Brenda Mulkey, 48, died early Monday after a tree crushed her in the kitchen of her Adairsville mobile home last Wednesday as the tornado moved through the area.
"The tree fell on her head and crushed three disks in her back and she said it crushed her back bone into her tail bone," said neighbor Amanda Payne, who was a close friend of Mulkey's.
According to doctors, she also suffered a concussion during the incident.
Mulkey's husband said she had several other health issues that were made worse by the tornado, which ultimately led to her death.
Anthony Raines, 51, died while in bed in his mobile home near the center of Adairsville where the tornado left the most damage on Wednesday.
Along this tornado's extensive 900-yard-wide path, 95 structures were damaged in Bartow County. Of those, 31 were destroyed, 17 sustained major damage, and 47 had minor damage.
In Gordon County, at least 268 homes, including 66 mobile homes, were impacted. Of the 202 site-built homes, 30 were completely destroyed, 110 had major damage, and 70 sustained minor damage.
Along with the two tornado deaths, more than 15 others were injured.
This was the first killer tornado in the United States since June 24, 2012, breaking a record-long streak of 220 days without a tornado fatality.
