Speculation About How Oscar Pistorius Allegedly Killed His Girlfriend

INSIDE EDITION is learning new details as to how South African Olympic hero Oscar Pistorius may have killed his girlfriend.

It's the haunting last recorded words of the Blade Runner's girlfriend, shot to death on Valentine’s Day. The farewell message was filmed for a reality show just before Reeva Steenkamp was killed and broadcast Sunday as a tribute to the 30-year-old rising star.

"I'm going to miss you all so much. I love you very, very much,” said Steenkamp.

It comes as stunning new details emerge of how she was killed.

A dramatic depiction of what might have happened on that fateful morning came from a respected South African newspaper, quoting police sources. The Blade Runner's luxury home is called “Oscar’s House of Horrors." The first image in the depiction shows the couple in their bedroom. Pistorius allegedly fired at Steenkamp, hitting her in the hip. She fled to the bathroom and locked the door. That's when  Pistorius allegedly fired three more shots through the door, hitting his girlfriend in the head and arm. The final image depicts the Blade Runner carrying her lifeless body down the stairs where paramedics tried in vain to resuscitate her.

Cops also found a bloody cricket bat in the bedroom. Published reports claim Pistorius used it to bash his girlfriends skull in.

Everyone now is asking, what could have sparked the violence?

Roid rage may have played a role. Steroids were reportedly found in the home, along with evidence of heavy drinking.

The one-time Olympic hero remains in jail today awaiting a bail hearing. All upcoming races have been cancelled. His family denies all charges against him.

Meanwhile, Steenkamp’s devastated mom is speaking out.

She said, "All we want are answers, answers as to why this had to happen, why our beautiful daughter had to die like this?"

She is left with these moving last words from her beloved daughter, "You either make an impact in a positive way or a negative way. I'm going to miss you all so much. I love you very, very much."
