(CNN) -- Oscar Pistorius faced another day of relentless cross-examination Friday as the prosecution challenged his account of the killing of his girlfriend, Reeva Steenkamp. Prosecutor Gerrie Nel has accused the athlete of hiding the truth about the death of Steenkamp, whom he shot last year through a closed toilet door in his home in Pretoria, South Africa. His questions again sought to undermine Pistorius' reliability and credibility and to portray the Olympic athlete as someone who was inventing his version of events and "tailoring" evidence to suit his story. As Nel turned once again to the early hours of Valentine's Day 2013, he repeatedly challenged Pistorius over his actions in the moments leading up to Steenkamp's death.
