Nunez was mother to two young children, aged 5 and 4, according to Spain's ABC Sevilla. She was a housewife and met her husband, Jose Gaspar, when they were children, the news station reported. They had been married for four years.
"This can't be so," Gaspar told ABC Sevilla. "Today it has been Rocio, but tomorrow it could be someone else."
Regional health minister Marina Alvarez called the incident a "rapid, unusual and tragic" accident, according to the BBC. She said the elevator had passed safety tests earlier in August.
Authorities continue to investigate.
