The young man then ran into the house and pressed the panic button. Meanwhile, shots were fired and the woman was hit twice in the chest. She died shortly afterwards.
One was found in hospital with a gunshot wound to the neck. The other two were arrested in Alexandra. Two firearms were recovered.
She was discovered by a staff member at the hotel. There is no evidence of a struggle or forced entry.
We do not suspect any foul play at the moment but an inquest docket has been opened.
The content of the post-mortem report will not be made known until the inquest hearing, as this will be presented in court as evidence.
The whole house was virtually emptied and although the Johannesburg police's serious and violent crime unit is investigating, no one has been arrested so far.
