Oscar Pistorius Sentencing Hearing: Olympic Athlete Deemed Unfit To Testify

South African athlete Oscar Pistorius was deemed unfit by a clinical psychologist to testify at his sentencing hearing that began Monday.

The double-amputee Olympian was convicted of murdering his girlfriend Reeva Steenkamp. He shot her four times through a locked toilet door in February 2013. He has maintained that he had mistaken Steenkamp for an intruder.
