Three witnesses were called by Oscar Pistorius's defence team yesterday to testify in his murder trial in the High Court in Pretoria.
Head of anaes-the-siology at Wits University, Christina Lundgren, was brought in to give the court her opinion on gastric emptying.
This related to the time Steenkamp had her last meal.
Social worker, Yvette van Schalkwyk testified that the athlete was emotionally distraught and heartbroken after the shooting.
Cross-examined by prosecutor Gerrie Nel, Van Schalkwyk conceded she had never dealt with other accused people in a "family murder case".
Finally, the defence called Wollie Wolmarans, a ballistics expert with decades of experience.
He said an accurate determination of the sequence of the shots or Steenkamp's body position when she was shot was not possible.
Wolmarans continues his testimony on Friday.
