The fourth day of Yung Filly’s trial saw the jury hear further expert medical evidence, emotional family testimony and continued cross-examination, as both the prosecution and defence continued presenting their cases in the Perth District Court. The court first heard from forensic dentist Dr Giuseppe Marcell, who gave evidence about injuries sustained by the complainant.

Dr Marcell told the jury that several injuries previously discussed in court were consistent with human bite marks, suction or soft tissue compression. He described arch-shaped bruises and abrasions on the complainant’s face and neck, saying some were consistent with bite marks from human teeth, while others could have been caused by tongue thrusting or suction. However, under cross-examination, he confirmed he was unable to identify who caused any of the bite marks.

Dr Marcell’s evidence differed in several respects from medical evidence heard on day three, where another doctor had attributed some injuries to blunt force trauma and strangulation. Following the dentist’s testimony, the judge questioned the prosecution about how parts of its case aligned with the expert evidence, asking which injuries supported allegations that the complainant had been slapped. The prosecution did not provide a direct answer during that exchange.

The court then heard from another doctor, who told the jury the complainant had an open wound on her right breast and required a tetanus injection. During cross-examination, the defence pointed out the wound was not visible in photographs taken on the same day as the medical examination. The doctor also said the complainant’s white blood cell count was elevated but agreed this could be caused by infection, drug use or dehydration.

The complainant’s cousin later returned to the witness box, where the defence highlighted several differences between her evidence and previous accounts given during the trial. She told the court the complainant had been drinking orange juice mixed with vodka at the festival, despite earlier evidence suggesting she had not consumed alcohol. She also said her mother had driven them to the festival, while the complainant had previously told the court they had walked.

The defence also referred to a recent witness statement in which the cousin said the festival “was a bad time” and that she “didn’t have fun at all.” When questioned, she accepted she had made those comments during a witness proofing session earlier this month.

The complainant’s aunt also gave evidence, becoming visibly emotional as she described seeing her niece the following day. She told the jury the complainant’s face was badly swollen, bruised and marked around the neck, leaving her in what she described as a “dreadful state.” She said she urged her niece to report the incident to police before driving her to a Sexual Assault Resource Centre for treatment.

However, during cross-examination, the aunt said she had not driven the complainant to the festival, differing from the cousin’s evidence given earlier in the day.

Later in the proceedings, the defence played around 16 videos recorded at the festival showing the complainant and her cousin dancing together and taking part in a mosh pit. The footage formed part of the defence’s cross-examination of witnesses and was shown to the jury alongside other evidence heard throughout the trial.

Yung Filly, whose real name is Andres Felipe Valencia Barrientos, has pleaded not guilty to all 10 charges, including rape, assault and choking. The allegations relate to an incident alleged to have taken place after a performance in Perth in September 2024. The trial continues before a jury in the Perth District Court.
