PRETORIA, South Africa (AP) - A psychiatrist for the defense says he believes Olympic runner Oscar Pistorius has an "anxiety disorder."
Dr. Merryll Vorster testified today at the double-amputee's murder trial in South Africa.
Vorster testified that the amputation of Pistorius' lower legs as a baby and other events in his life contributed to his "increasing stress."
The defense argues that Pistorius' feelings of "vulnerability" contributed to his shooting girlfriend Reeva Steenkamp by mistake, fearing she was an intruder.
