One of the four men accused of murder and robbery was acquitted by the Johannesburg High Court yesterday.
Phana Makhanya who was accused number one in the case, was discharged because Judge Nigel Willis could not find evidence "of a direct nature" that linked him to the crime.

Menzi Hlongwa, 20, Siphamandla Sigidi Gasela, 22, and Phikani Sibongiseni Ngidi, 24, are still standing trial. The trial is a sequel to a robbery in the city centre in which 15-month-old baby Khensani Mitileni was shot while on her mother's back.
