Pistorius Argued With Girlfriend Before Shots: Prosecutor

Oscar Pistorius, the South African double amputee track star, argued with girlfriend Reeva Steenkamp before shooting her dead at his home, prosecutors said.

Pistorius, 26, lowered his face as lead police investigator Hilton Botha today contested his affidavit that he thought Steenkamp was a burglar when he fired four shots at the toilet on Feb. 14. Pistorius and Steenkamp, 29, had argued between 2 a.m. and 3 a.m., prosecutor Gerrie Nel said in court, citing a witness. The call for an ambulance was made at 3:20 a.m., defense attorney Barry Roux said.
