PRETORIA, South Africa (AP) — Oscar Pistorius is testifying for a third day at his murder trial, returning to the witness stand after breaking down in sobs and wailing a day earlier while describing the moments he said he realized he had fatally shot his girlfriend by mistake.

Pistorius was still being led in questioning Wednesday by chief defense lawyer Barry Roux, but could also be cross-examined by prosecutor Gerrie Nel, who maintains the double-amputee runner killed Reeva Steenkamp after an argument. Pistorius is charged with premeditated murder.

Pistorius broke down Tuesday as he recalled bashing open the toilet door through which he shot Steenkamp last year. Pistorius said he noticed "she wasn't breathing" and then sobbed and howled in court, causing the trial to be adjourned.
