The chest freezer was closed with duct tape when it was at her neighbor's yard sale.
"A church was supposed to come, pick up the items inside the freezer," she said.
"I was supposed to get the freezer back. The church never came. I decided to open it."
When she realized what was inside, she called 911.
"I have a serious problem. My neighbor sold me a deep freezer. I just opened it and there’s a body in there I think," she told the 911 dispatcher. "I am freaking out."
WNCN reported that police arrived at the Goldsboro residence Friday and confirmed that a body was inside and intact.
The body was that of the seller's mother, who left town and said she was moving to West Virginia after she sold the freezer, according to the buyer.
"She sold me her frozen mother for $30. How do you do something like that?"
"(She was) Just the sweetest lady. I mean quiet, kept to herself, stayed at home. Just unbelievable how she could just stick her mom in a freezer," the woman said.
The North Carolina Medical Examiner’s Office said the woman's death was natural and there were no signs of foul play.
Police are investigating the incident. It is regarded as a felony for failing to notify or concealing the death of a person.
