Media reports during the second trial suggested the location of the body was an essential component to the Crown case that Ms Byrne was not pushed nor jumped, but was forcefully thrown to her death. The court heard that Caroline's mother Andrea Byrne had committed suicide in March 1991 after she became depressed following a breast enlargement operation that went wrong. Terracini also read to the court a letter Tony Byrne had previously provided to police in which he claimed that Caroline had made an attempt on her own life via overdose in 1992. In court Tony Byrne denied that Caroline had on that occasion intended to kill herself and instead was making "a cry for help". At another stage of the cross examination, he claimed to suppose that had Caroline wanted to kill herself she would have copied her mother's method rather than jumping from a cliff. Byrne's doctor, author and television personality Cindy Pan, gave evidence that she had seen Byrne for two years before her death and had specifically discussed Byrne's depression with her in the weeks leading up to her death. Pan told the court Byrne said she had felt depressed for about a month and the condition had worsened in the week leading up to their appointment on 5 June 1995. Pan said the model told her she could not put a finger on what she was unhappy about. "I was trying to explore with her what she might be depressed about, but she was not really able to identify any one specific thing," Pan told the court. She said Byrne told her she "had the same thing three years ago" and had been put on medication, which had helped. Pan said Byrne denied having thoughts of self-harm and she referred her to a psychiatrist, obtaining an appointment for 4 pm on 7 June. One defence witness, Prof John Hilton, a forensic pathologist, was called during the Prosecution case, due to his later unavailability. Otherwise Terracini commenced the defence case on 27 October 2008 calling another physics expert Prof Marcus Pandy, a biomechancial engineer who conducted experiments on running and jumping speeds of two females. Only a handful of defence witnesses were called – two forensic pathologists, one psychiatrist, Prof Pandy, a stunt diver, and Wood's sister Jacqueline Schmidt – and the defence case concluded within a week. With the trial drawing to a close, the jury made a number of requests of Justice Barr that included a visit the Gap for a third time; for a transcript of Doherty's evidence; and for video footage of Pandy's running experiments. For the first time in New South Wales court history, a ballot was used to select the three jurors who would stand down so that twelve of the sitting fifteen would deliberate to a verdict.
