Pistorius shot girlfriend through door: prosecutor
He shouted for the intruder to get out of his house then fired several shots into the door, before calling to Steenkamp to phone the police.
When she did not respond, he grabbed a cricket bat to beat down the door and found her slumped on the floor, he said.
"I was absolutely mortified by the events and the devastating loss of my beloved Reeva," he said in the affidavit.
As Roux read the statement, Pistorius sobbed unrestrainedly, prompting magistrate Desmond Nair to halt proceedings for several minutes. "You need to concentrate on what's going on," Nair told him.
The bail hearing was adjourned until 0700 GMT on Wednesday.
