PRETORIA, South Africa — For two days, the witness in the murder trial of Oscar Pistorius kept her composure. Then, just as her testimony was about to finish, she broke down in tears at what she said was the memory of the screams she heard on the night that the double-amputee athlete fatally shot his girlfriend in his South African home. Michelle Burger, a neighbor of Pistorius who took the stand on the second day of a trial watched around the world, remained calm through intense questioning by the chief defense lawyer.
