Johannesburg -

The State is expected to continue its cross-examination of Oscar Pistorius's agent, Petrus van Zyl, at the North Gauteng High Court in Pretoria on Wednesday.

Prosecutor Gerrie Nel began his cross-examination on Tuesday, but requested that court adjourn early so that he could better prepare himself.

Van Zyl testified on Tuesday that Pistorius had planned to take his girlfriend, Reeva Steenkamp, to two of his athletics meetings in Manchester and Brazil, which was the first time the athlete had asked a girlfriend to accompany him to sports meetings.

The travel plans were discussed on February 7, 2013, while he was visiting the athlete to plan their year. This was seven days before Pistorius shot and killed Steenkamp.

Pistorius had also planned to take Steenkamp to an Andrea Bocelli concert in Tuscany, Italy, the court heard.

Nel completed his questioning of sound expert Ivan Lin's report on ambient noise on the morning of the shooting.

Lin did not rule out the possibility that one of Pistorius's neighbours, Michelle Burger, whose house is 177m from Pistorius's, could have perceived what she heard that night as a woman's screams.

Burger told the court in March she heard “blood-curdling screams” followed by four gunshots the morning Steenkamp was shot dead.

Lin said the perception of what one heard was not reliable.

He said it was common sense that more often than not a woman's voice could be distinguished from a man's, but that one could not be 100-percent certain. - Sapa
