A police officer and his wife have been found dead in the hot tub of a Brazilian motel.

The lifeless bodies of Jeferson Sagaz, 37, and Ana Silva, 42, were discovered at the Dallas Motel in the city of São José on Tuesday night.

Neither body showed any sign of violence or struggle, according to the authorities probing their deaths.

Santa Catarina Civil Police chief Felipe Simão told Brazilian news outlet G1 that they have not ruled out the possibility that the couple was murdered and are also looking into whether they died by accident or committed suicide.

Simão added that it's 'important that speculation about the cause of death and the couple's private life be avoided.'
