Reeva Steenkamp's sister slams Pistorius documentary: 'We don't need photos of her blood stains'

Reeva Steenkamp's sister has condemned a new Amazon Prime documentary about Oscar Pistorius for displaying graphic images from the scene of the model's death.

On Valentine's Day 2013, Steenkamp was shot dead by Pistorius, her boyfriend of four months, in his home in Pretoria, South Africa.

The former Olympic and Paralympic sprinter, who is now serving a 13-year jail sentence, claimed he mistook her for an intruder hiding in his bathroom, prompting him to fire four shots through the locked door.

Five years on from her death, Steenkamp's sister is horrified that images of her dead body, the blood-splattered crime scene and the weapon that ended her life are featured in the four-part documentary, Pistorius.

"I don't believe it is necessary to show blood stains on the walls. All this was told as evidence at Oscar's trial," she says, adding that she is concerned about the impact of the series on her parents.

"I spend a lot of time shielding my parents from what is on the internet about Reeva. We don't need pictures of her blood stains to be seen at all after such a long time.

"I am worried this will have a terrible effect on them."

"If his family are involved and trying to get him a reduced sentence, I hope it fails," she tells the Daily Mail.

"He needs to stay in prison for a long time for the way he killed my sister."

During Pistorius' trial, the prosecution argued he and Steenkamp, a law graduate and model, had been embroiled in a heated argument that spurred him to lose control and shoot her.

The conviction was overturned and upgraded to murder the following year.

A South African appeal court more than doubled his original six-year jail sentence, labelled "shockingly lenient" by state prosecutors, last November.

The court declared Pistorius, 31, displayed "a lack of remorse", and did not "appreciate the gravity of his actions."
