It was revealed for the first time this week that Frank Chiziweni was in his quarters inside the athlete's home when Reeva was shot through a closed bathroom door and killed.
The housekeeper has claimed that he slept through the entire incident, with one of the first policemen on the scene testifying that Frank had told him he hadn't heard anything of the shooting that morning.
The policeman added: 'We were all asking ourselves how he could not have heard anything.'
Neighbours from Pistorius' estate have given accounts of what they heard on the night of model Reeva's death, with some saying they heard 'bloodcurdling screams,' whilst others testifying that they only heard cries for help from a man.
According to Pistorius' barrister Barry Roux, they will not be calling the housekeeper to the stand because he maintains that he heard nothing of the incident.
Yesterday, the court heard from neighbour Johan Stander, who told of how when he arrived at Pistorius' house on the night of the shooting, the athlete was coming downstairs with the fatally injured model in his arms.
He added that the Paralympian was 'really crying, he was in pain, he asked us to please assist him to put Reeva in the car and take her to hospital.'
'He begged her to stay with him, begged God to keep her alive.'
Johan backed up Oscar's story that he had shot his model girlfriend in error, referring to the athlete's dedication to saving Reeva's life in the moment's after the shooting.
'I saw the truth that morning. I saw it and I feel it' he said.
The trial continues Thursday 8 May.
