PRETORIA, South Africa (AP) —Oscar Pistorius held his head in his hands and wept openly in court Friday as prosecutors said they would pursue a charge of premeditated murder against the Paralympic superstar. Pistorius was formally charged at Pretoria Magistrates Court with one count of murder for the slaying of his girlfriend, Reeva Steenkamp, a model and budding reality TV show contestant. The 30-year-old was shot multiple times and died at Pistorius ' upmarket home early Thursday morning. Prosecutor Gerrie Nel said Friday in court it was premeditated murder, indicating the prosecution would file that more serious charge, upgraded from murder. The double-amputee athlete's arrest and murder charge had already left South Africa stunned after Steenkamp's death on Valentine's Day at Pistorius ' house in a gated community in an eastern suburb of South Africa's capital, Pretoria. Following the hearing, Pistorius family and his London management company issued a statement calling into question the criminal charge the 26-year-old athlete faces. "The alleged murder is disputed in the strongest terms," the statement read. The statement did not elaborate. The statement also said Pistorius wanted to "send his deepest sympathies to the family of Reeva." "He would also like to express his thanks through us today for all the messages of support he has received — but as stated our thoughts and prayers today should be for Reeva and her family — regardless of the circumstances of this terrible, terrible tragedy," the statement read. Those who knew Pistorius, including a former girlfriend, also weighed in on social media. Trish Taylor, mother of Pistorius ' ex-girlfriend Samantha Taylor, wrote on Facebook: "I'm so glad Sammy is safe and out of the clutches of that man." But another ex-girlfriend, Jenna Edkins, defended Pistorius in messages Friday on Twitter. "All I am saying is let him speak, let his side be heard without jumping to conclusions," Edkins wrote. She offered "love and support" to the Pistorius family and wrote: "I have dated Oscar on and off for 5 YEARS, NOT ONCE has he EVER lifted a finger to me or made me fear for my life." Prosecutors said Friday that they would argue the history-making Olympic athlete — the first amputee to run at the games — had planned Steenkamp's killing. It sent South Africans reeling further as their national hero, and a global role model in overcoming adversity, was set to face accusations that he intentionally gunned down his girlfriend.
