The judge in the murder trial of Oscar Pistorius says she will give a verdict on Sept. 11.

Judge Thokozile Masipa made the announcement on Friday after the prosecution and the defense ended final arguments in the murder case against the double-amputee, who shot dead girlfriend Reeva Steenkamp on Valentine's Day last year.

Pistorius said he mistakenly shot Steenkamp, thinking there was intruder in his home. The prosecution alleges the Olympic runner intentionally killed her after an argument.
