Oscar Pistorius is facing jail after being found guilty of manslaughter for shooting dead his girlfriend Reeva Steenkamp.

Judge Thokozile Masipa said the double amputee had been "negligent" on the night he killed the model at his Pretoria home.

The Paralympian and Olympian, dubbed Blade Runner due to his prosthetic limbs, had always admitted he shot Ms Steenkamp.

But he said he mistook her for an intruder and fired four bullets from his 9mm pistol through the toilet cubicle.

Judge Masipa criticised Pistorius' decision to reach for his gun and open fire rather than raise the alarm or fire a warning shot.

She also accused him of being a poor witness, muddled over his defence and a liar.

Pistorius showed little emotion as the guilty verdict of culpable homicide, which is South Africa's equivalent of Irish manslaughter, was handed down.

The charge carries a maximum jail term of 15 years and he is expected to be sentenced in a couple of weeks.

The judge told him: "A reasonable person therefore, in the position of the accused with similar disabilities would have foreseen that the possibility that whoever was behind the door might be killed by the shots."

"And would have taken steps to avoid the consequences and the accused in this matter failed to take those consequences."

Ms Steenkamp's father Barry leaned forward in his seat when the manslaughter verdict was read out. Her mother, June, showed no reaction.

Yesterday, the double amputee broke down in the Pretoria courtroom as he was cleared of two murder charges over the shooting.

The judge said he did not intend to kill anyone and could not have seen that the intruder he thought was hiding in his toilet was actually Ms Steenkamp.

Today, she told the courtroom: "Having regard to the totality of this evidence in this matter, the unanimous decision of this court is the following: on count one, murder...the accused found not guilty and is discharged."

"Instead he is found guilty of culpable homicide."

The judge began the day's events by dealing with the three firearms charges which were unrelated to last year's Valentine's Day shooting.

Pistorius was found guilty of discharging a firearm at a restaurant on January 11th, 2013.

But he was acquitted of firing a gun through a car sunroof while with his then-girlfriend Samantha Taylor and friend Darren Fresco on November 30th, 2012.

He was also cleared of illegally possessing .38 ammunition. Pistorius denied all three charges.
