Roux said Pistorius did make calls, including to the guards of the housing estate. In one case, he said, a guard could hear Pistorius crying.
"Was it part of his premeditated plan, not to switch off the phone and cry?" Roux asked sarcastically.
Botha said Pistorius did not have a license for a .38-caliber weapon and consequently his possession of ammunition for such a weapon was illegal.
The detective said that all Pistorius would say after the shooting was "he thought it was a burglar."
In an additional revelation Wednesday, police said they found two boxes of testosterone and needles in the Pistorius' bedroom.
But Roux said the substance was an "herbal remedy," and not a steroid or a banned substance.
Police "take every piece of evidence and try to extract the most possibly negative connotation and present it to the court," defense lawyer Roux said.
