The murder trial of Oscar Pistorius kicked off Monday morning in South Africa with a neighbor who described the screams she heard coming from the Olympian's home, which she said were followed by four gunshots.
Pistorius, a double-amputee track star who has been nicknamed "Blade Runner," pleaded not guilty to premeditated murder in the death of his girlfriend, Reeva Steenkamp. He has never denied killing her on Valentine's Day last year, but says he mistook her for an intruder.

Here are the highlights from the first day of trial as played out in short Instagram videos:
The charges against Pistorius are read in court. He pleads "not guilty."
Did you notice how Pistorius didn't address the judge as "your honor"?
Kenny Oldwage, who is on Pistorius' defense team, says in his opening statement it was an “accident” and that Pistorius mistakenly believed an intruder (or intruders) had entered his home and “posed an imminent threat to Reeva and me.”
The prosecution's opening statement was super short.
Michelle Burger lives near Oscar Pistorius. She chose to not be filmed while testifying and spoke through an interpreter: "She screamed terribly and she yelled for help," Burger said. "Then I also heard a man screaming for help, three times he yelled for help."
Burger describes the gunshots she heard early that morning: “Bang… bang bang bang.”
In a break from speaking her native tongue of Afrikaans in the courtroom, Burger asks to speak in English to be clear about the evening she witnessed: "The fear in that woman’s voice is difficult to explain to the court," she said.
Burger goes on to say: "It was a very emotional situation to have to hear. The absolute petrified screams and shouts."
Those screams are a key to the case, according to Politan, since they could help disprove Pistorius' self-defense claim.
