A woman hurt in a freak explosion at an Australia café has died.

Serves You Right Café manager Nicole Dempsey, a 37-year-old mother of two, died after suffering burns on 80 percent of her body.

Security footage captured the horrific blast earlier this week. Authorities say that the driver of a truck lost control of his vehicle and plowed into gas tanks at the back of the café, triggering the explosion.

Authorities believe the driver may have suffered a heart attack before the crash. He is now in a medically induced coma.

Officials say 20 people were hurt – eight critically – in the explosion.
