PRETORIA, SOUTH AFRICA—Minutes after Oscar Pistorius shot his girlfriend Reeva Steenkamp, he told a security guard that “everything is fine,” a South African court heard Friday.

Pieter Baba, who works at the Silverwoods Country Estate in Pretoria, testified that residents in the gated community heard shots coming from the athlete’s home early on Valentine’s Day last year.

Baba called the Paralympic sprinter to investigate. “Mr. Pistorius said to me, ‘security, everything is fine,’” he said.

But Baba could hear Pistorius crying.

“Not everything was in order as Mr. Pistorius was telling me,” he testified.

As the Pistorius trial resumed Friday, the court heard Baba’s eyewitness account of the crime scene, as well as emotional testimony from Pistorius’s ex-girlfriend that painted the runner as gun-crazed.

The state alleges that Pistorius, a global star whose meteoric fall from grace is making international headlines, shot his 29-year-old girlfriend in a fit of rage following an argument.

Pistorius maintains he shot Steenkamp through a locked toilet door, believing her to be an intruder.

The runner has pleaded “not guilty” to intentionally killing Steenkamp and three other charges related to the illegal possession of firearms and ammunition.

Defence lawyer Barry Roux argued that Pistorius had said “I’m fine,” not “everything is fine,” yet Baba was adamant he heard the runner correctly.

“We’ll deal with that Monday,” said Roux when court adjourned for the day.

Roux’s week started on a high note as he successfully planted seeds of doubt, suggesting a married couple’s testimony had “striking similarities,” indicating collusion and contamination.

However, state prosecutor Gerrie Nel kept calling progressively more credible witnesses to the stand, climaxing at the end of the week with Baba and Pistorius’s ex-girlfriend, Samantha Taylor.

Still, the state has yet to spell out its exact version of events, complete with times, the night Pistorius shot Steenkamp.

The state and defence go head to head over the chronology of the evening, disputing when Pistorius screamed, used a cricket bat to break down a bathroom door, and fired the fatal headshot, one of four fired at Steenkamp.

Taylor testified that Pistorius often carried a gun and once shot at a traffic light to “spite” the police.

She broke down twice during her testimony as she recounted her troubled relationship with the sprinter. Pistorius, wearing a dark suit with a crisp white shirt and tie, watched as she was consoled by her sister, clenching his jaw repeatedly as Taylor cried in the witness stand.

Taylor said her relationship with Pistorius ended in November 2012, when the Paralympian, one of most recognizable names of the London Olympic Games, appeared at the South African Sport Awards with Steenkamp, a law graduate and model.

Pistorius and Steenkamp denied being an item at the time. “It’s just a coincidence that we’re sitting at the same table and arrived in the same car,” Steenkamp told City Press, a local newspaper, when asked about her relationship with Pistorius.

Taylor, who met Pistorius in 2010 when she was 17, recounted a time when Pistorius and a group of friends were returning from a holiday. Their car was pulled over by police for speeding and the officer found a gun. Pistorius, angered by the confrontation, later shot through the car’s sunroof at a traffic light.

“He was angry at the police after being stopped, thereafter when they wanted to fire a shot they found it funny,” she said, referring to Pistorius and Darren Fresco, a friend who was with him at the time.

Earlier in the week, the court heard testimony from professional boxer Kevin Lerena, who said Pistorius accidentally discharged a gun at a popular Johannesburg eatery. Lerena said on Wednesday that Pistorius asked Fresco, one of the four people at the table, to take the blame.

Nel asked Taylor to describe the sound of Pistorius’s voice when he was anxious. For the past week, the defence has said it was not Steenkamp screaming in the dead of the night, but Pistorius, whose voice pitches high “like a woman” under severe stress.

“Have you heard him scream?” asked Nel.

“Yes, a few times my lady,” Taylor told the judge. “He sounded like a man.”

The trial resumes Monday.
