Oscar Pistorius was "heartbroken" after shooting Reeva Steenkamp to death, which he claims was an accident, his trial has heard.
The comments came from a social worker who came forward after it was reported Pistorius had taken acting lessons to make his grief during the trial appear genuine.
Pistorius denies murder and claims he shot Steenkamp after mistaking her for an intruder in the early hours of Valentine's Day, 2013.
After the death, Pistorius visited social worker and probation officer Yvette van Schalkwyk, who said he was extremely upset.
On Wednesday, she told the court: "What I saw from the first time I saw him was a man who was heartbroken... he cried, he was in mourning, he suffered emotionally.
"He was very sorry for the loss, especially for the parents, what they were going through."
Her evidence was grilled by 'The Pit Bull' prosecutor Gerrie Nel, who pushed her on whether Pistorius had ever said sorry for killing Steenkamp.
When she replied yes, he said: "It was never the evidence that he said he was sorry."
She added: "He was sorry for his loss, he was sorry for her parents."
Nel said this was not the same as being sorry for killing her, adding: "'I miss Reeva, I'm sorry for her loss'. It's all about him. It's not 'sorry for what I've done.'"
Van Schalkwyk described being with Pistorius before bail hearings in February 2013, shortly after Steenkamp's death.
She said: "I sat with him in the cells. He vomited twice, one time after he came out of court. He said 'I miss Reeva'."
