JOHANNESBURG (AP) — With his past triumphs now tarnished because he shot to death his girlfriend, Oscar Pistorius on Monday will enter court to be confronted with the jarring possibility that he will be sent to prison for at least 25 years.

For the champion runner without legs, who trained himself to overcome all obstacles, nothing else matters now but beating the murder charge against him. Pistorius’ family said Saturday that their focus is only on the trial. If found guilty, Pistorius’ entire life story will be recast.
