Pistorius Witness Describes 'Terrified' Screaming

Oscar Pistorius talks on a mobile phone while waiting for proceedings to get under way in court in Pretoria, South Africa, March 24, 2014.

Week four of the Oscar Pistorius trial began Monday with a neighbor saying she heard screams from both a woman and a man on the morning the athlete shot and killed girlfriend Reeva Steenkamp.

The testimony from Anette Stipp was consistent with other witnesses who said they heard a woman's screams coming from the home of Pistorius around 3 a.m. on February 14, 2013.

Defense lawyers have argued neighbors were actually hearing Pistorius scream in a high-pitched voice.

Pistorius has acknowledged killing Steenkamp, but says he thought he was shooting at an intruder through a bathroom door. Prosecutors say the shooting was deliberate.

Questioned by prosecutor Gerrie Nel, Stipp testified that she heard gunshots followed by what she called "terrified, terrified screaming" from a woman. Stipp also said she heard a man screaming. She said all the screaming stopped after a second set of shots.

The witness said she told her husband Johan, who testified earlier in the trial, that she thought a "family murder" had taken place.

Pistorius has pleaded not guilty to charges of premeditated murder. The South African court hearing the case said Monday that after a two-week recess in April, the trial will continue until May 16.
