Testifying before Blantyre High Court Judge Dorothy Kamanga, Chileka also implicated Dr. Hetherwick Ntaba who is being mentioned the second time after another suspect Alfred Yohane also named him.
Lawyer for the suspect Masauko Chamkakala of the legal aid Bureau could not be drawn to discuss much on the allegations made by his client in court.
