PRETORIA, South Africa (AP) — Oscar Pistorius had a heightened concern for his personal safety and was making plans to take girlfriend Reeva Steenkamp on international trips shortly before he fatally shot her, his agent testified at the double-amputee runner’s murder trial Tuesday.

The defense called Peet van Zyl to the stand in an attempt to bolster Pistorius’ account that he mistook Steenkamp for an intruder, providing testimony about a loving relationship and a fear of crime that may have pushed the Paralympian to fire through a closed toilet door.
