Oscar Pistorius held his head in his hands and wept openly in court today as prosecutors said they would pursue a charge of premeditated murder against the Olympian.

Pistorius was formally charged at Pretoria Magistrate's Court with one count of murder for the slaying of his girlfriend, Reeva Steenkamp, a model and budding reality TV show participant. 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 has left South Africa reeling after the model's shooting death at Pistorius' house in an eastern suburb of the South African 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. It 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 five 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.

South Africa's tabloid Citizen newspaper had the headline "Blade gunner?" Friday morning, playing on double-amputee athlete Pistorius' well-known nickname of "Blade Runner" because of his carbon fiber running blades.

Chief Magistrate Desmond Nasir delayed Pistorius' bail hearing until next Tuesday and Wednesday and ruled that the 26-year-old Pistorius would be held at a police station in Pretoria until then. Police have said they oppose the granting of bail.

Pistorius weeps in packed courtroom

Pistorius had solemnly entered the court wearing a grey suit and blue tie and initially appeared composed. When he broke down in tears, his brother, Carl, reached out a hand and placed it on his shoulder. Pistorius' father, Henke, was in the court and later reached over to comfort him as well.

More than 100 people packed into Courtroom C at Pretoria Magistrate's Court, including dozens of photographers and videographers. Nasir ruled that no recordings of court proceedings would be allowed in the case.

Police said Friday an autopsy on the body of the victim was also taking place. Lt. Col. Katlego Mogale said the results of the autopsy would not be published.

The Paralympian and Olympic athlete was earlier seen leaving a police station, his jacket completely covering his head as he got into a police vehicle.

He was holding what appeared to be a white handkerchief in one hand as he was led by officers to a police van outside the Boschkop Police Station in eastern Pretoria, where he had been questioned on Thursday and had spent the night in custody.

A policeman was also seen carrying a handgun in a plastic forensic bag outside the Boschkop station. It was believed to be the weapon used to shoot and kill Steenkamp.

Police said the victim was shot four times at Pistorius' villa in a gated community. Officers found a 9 mm pistol inside the home.

Pistorius made history at the London Olympics last year when he became the first double-amputee track athlete to compete at any games. He didn't win a medal but did make the semifinals of the 400 metres and the final of the 4X400 relay, propelling the world's best-known Paralympian to the level of an international track star.
