Pistorius has a history of troubles with women. Last year, Pistorius allegedly threatened to break the legs of a man whom he suspected of being involved with his then-girlfriend while Pistorius was in London for the Olympics. “[Pistorius] carries a gun everywhere and I have seen him be controlling to women,” said Mark Batchelor, a friend of the man Pistorius threatened. After they broke up, Pistorius’s ex-girlfriend, Samantha Taylor, told South Africa’s Rapport newspaper that she was “prepared to reveal what (Pistorius) made me go through;” on advice from her lawyers, she later withdrew her statement. In 2009, Pistorius was arrested and charged with common assault after slamming a door on a woman with whom he had fought at a party. (The charges were later dropped, and Pistorius sued the woman and the police.)
It’s not clear, however, whether Pistorius and Steenkamp had problems. Some have speculated that Steenkamp had received text messages from ex-boyfriend Francois Hougaard, a South African rugby player, and that this precipitated an argument between her and Pistorius. These rumors are entirely unconfirmed, and Hougaard has issued a statement denying any involvement in the shooting. Independent correspondent Daniel Howden tweeted that, in Tuesday’s hearing, a friend of Steenkamp’s said that “Steenkamp told her Oscar treated her like gold. Said she would marry him if he asked.” The two had been dating since November 2012.
Pistorius is jumpy. In an article for The Times of London, Fay Schlesinger and Rick Broadbent wrote:
"The sprinter has spoken of his excess energy, his determination and his recklessness - the keys to his success, but also the reason he has lived on a knife edge.
He goes to bed as early as 8pm but struggles to sleep. After he got rid of his television and set his phone to turn off automatically he would read books voraciously. He told The New York Times that when a house security alarm went off recently, he grabbed the gun he kept by his bed and crept downstairs. It turned out to be nothing."
In November, he tweeted about mistaking his washing machine for a burglar. (“Nothing like getting home to hear the washing machine on and thinking its an intruder to go into full combat recon mode into the pantry!” he wrote) A few weeks before he shot Steenkamp, he almost shot a friend in a restaurant when a gun he was holding accidentally discharged.
Many South Africans are terrified of burglary. South Africa is a country with a violent history and a police force that is widely considered corrupt. As such, many South Africans take self-protection into their own hands. A GlobalPost article reported that South Africa’s “intruder detection services industry is estimated to be a 60 billion rand ($6.8 billion) market.” Many South Africans supplement this external security by arming themselves. In his affidavit, Pistorius claimed that “I have received death threats before. I have also been a victim of violence and of burglaries before. For that reason I kept my firearm, a 9 mm Parabellum, underneath my bed when I went to bed at night.” He went on to note that the bathroom did not have any bars on its windows, and that contractors had left ladders outside the house.
Pistorius’s house was located in Silver Woods Country Estate, a gated ”security village” that, according to its website, is “enclosed with a solid, electrified security wall with strict access control utilizing the latest security measures throughout the estate.” The house was in the east of Pretoria, one of South Africa’s three capital cities. It is worth approximately 5 million rand, or $560,000. It does not appear that Steenkamp lived with Pistorius.
