Police eventually dropped their negligent driving charge against Pistorius.
CNN has repeatedly asked the Pistorius family and his lawyers for comment but has been told there would be none. He is next due in court on June 4.
The police have refused to discuss any part of their investigation.
CNN also attempted to reach other friends, colleagues and associates of Pistorius, but all have withheld comment on their relationships with him.
There's little doubt that Pistorius' character and his previous run-in with authorities will be key issues brought up by prosecutors during his trial.
In the meantime, Pistorius has been released on bail and awaits his fate at his uncle's multimillion-dollar mansion in Pretoria, South Africa. He's no longer required to visit police twice a week under the terms of his bail. Instead authorities will now visit him at his uncle's -- and only occasionally.
However his critics viewed him, even the friends who criticized Pistorius' actions defended him.
"He was a good guy," Lerena said, "could have fun with his mates ... but never was he reckless and ever in my company aggressive toward anyone."
