A photograph taken by a Google Maps car has cast new doubt on the death of two young Saudi sisters, before their bodies were found decomposing.

Asra Abdallah Alsehli, 24, and Amaal, 23, were found dead in separate rooms of the apartment, with police so far baffled as to how they died.

Police made the gruesome discovery on June 7 during a welfare check at their home in Canterbury, New South Wales.

Since then, several theories have been published about their deaths, with some claiming that a faulty heater filled the room with deadly carbon monoxide.

A photo taken by Google Maps in May - after the sisters were said to have died but before they were found - showed a kitchen window slightly open, says .

If the timestamp was correct, this would dispel the carbon monoxide poison theory as the odorless gas would have been pumped out the window.

Other theories police are investigating include the possibility that the couple planned their deaths after bottles of chemicals and other substances were found next to the siblings' bodies.

They included a bottle of bleach, non-perishable food and clothing.

The Guardian later reported that police in New South Wales were investigating whether either or both sisters feared persecution for their sexuality in their home country.
