Mr Bradnick told TimesSelect she was one of several people involved in a vehicle accident which left two others dead on Sunday, 24 June.
A morgue source told TimesLive a colleague realised the woman was still alive when he checked on bodies in the mortuary fridges.
The dead giveaway came when staffers at the Carleton morgue in South Africa pulled the woman's body out of the refrigerator and found she was very much alive, according to Times Live.
Ambulance service Distress Alert confirmed that the unnamed woman had been certified dead by paramedics at the scene of the pile-up outside of Carletonville, southwest of Johannesburg, in the early hours of June 24.
"All the right checks were done - breathing, pulse - so the patient was declared deceased".
But when a morgue worker returned to check on the body in the fridge, he found the woman was breathing.
He said: "As a family we won't talk about this unless the police, paramedics and the mortuary officials who were involved are present".
'You never expect to open a fridge and find someone int there alive.
A member of the woman's family said that they were in shock and that they haven't been given any information.
It wouldn't be the first time someone has been declared dead but were actually alive all long. "The injuries, especially to her head, were so bad you could not work out her age or size", said Bradnick.
"That's all we want [answers] and we don't have any clarity now", one family member told the BBC.
Mr Bradnick said there's "no proof" his staff were negligent. Now, the Gauteng Health Department is trying to figure out how the misdeclaration of death happened.
