Oscar Pistorius is "on the verge of suicide" as he is forced to sell off his belongings to fight a charge of premeditated murder, a friend of the Paralympic star has said.
"Blade Runner" Pistorius, 26, is accused of murdering his girlfriend Reeva Steenkamp after she was shot dead at his home last month.
The Olympian claims he shot her through a bathroom door thinking she was an intruder.
Pistorius' fall from grace has transfixed people around the world
Close friend Mike Azzie, who Pistorius refers to as Uncle Mike, said the sportsman was a "broken man" after he was tasked with selling his racehorses to raise money to pay for spiralling legal fees.
Speaking in a BBC3 documentary, Oscar Pistorius: What Really Happened?, Azzie said Pistorius regularly talks about Steenkamp as he awaits his next court appearance on June 4.
He said: "He just always seems to mention Reeva and to ask us to pray for her and her family.
"But most of all, you've got to understand that we are there for him and we will always be his friend.
"He has no confidence in his tone of voice and he is just a man that is almost like someone that is walking around in circles and doesn't know where he is going.
"I would say that, just speaking to him, that he is a broken man and that I would go as far to say that he would be on the verge of suicide. It really worries me."
According to the documentary makers, Mentorn Media, police in Johannesburg said they have requested all records of phone calls and messages exchanged between Pistorius and Steenkamp on the day she was killed.
Officers added they were also sifting through a "massive" number of texts on Steenkamp's phone, producers said.
There are no plans for police to enter into a plea bargain with Pistorius' legal team for a lesser charge, the show's makers claimed.
The documentary, which airs tomorrow, shows Steenkamp's close friend Gina Myers take the cameras into her bedroom as she recalls the last time they were together.
She said: "I was actually, I was doing my hair and she was getting ready for a meeting and I was getting ready to go to work.
"And when she left she told me I was going to be awesome and that she loved me and then I ran out and then I gave her a hug and she left."
Ms Myers told the documentary that she hoped people would remember the 29-year-old's integrity and beauty.
"She was just the most incredibly bubbly person," she added.
"You could feel it as soon as she walked into a room, you could feel her presence. She had this way about her. I promise you if you'd met her you would just say hello to her and she had this smile.
"You know your immediate thoughts when you see someone that beautiful is it's impossible to have someone so magnificent on the inside as she is on the outside. But she really was.
"I want her to be remembered for the voice that she had and the things that she believed in and what she stood for. She had such an integrity about her and moral grounding. She comes from such a beautiful family."Oscar Pistorius: What Really Happened? airs on BBC3 tomorrow at 9pm.
