Defence witness Absolom Zungu returns to the High Court in Pretoria on Monday for the murder trial of former Bafana Bafana Captain Senzo Meyiwa.
Zungu allegedly gave investigators a breakthrough by linking two of the accused to the killing.
He is the father of key state witness Constable Sizwe Zungu, who placed all the accused at a Vosloorus hostel on the day of the murder.
