Under Investigation on Nine Network: The Case of the Murder of Irma Pelazic
The documentary series investigates the defense's explanation and the technical evidence in the case of the brutal home invasion against the Pelazic couple
What is the series about?
Under Investigation (Nine Network, 2025) sheds light on one of the most shocking home invasion cases in recent Australian history in the episode 'The Two Intruders: The Defence Case Emerges.' The documentary series follows reporter Elizabeth Byrne as she examines the technical evidence and legal challenges in the trial against the two men, Fbritzy and Vicone, who are accused of the deadly assault on the couple Gregor and Irma Pelazic. The focus is particularly on how the defense attempts to overturn the prosecution's presentation of the sequence of events by attacking the forensic findings.
The real case
The case of Irma Pelazic began when two perpetrators gained access to the couple's home through a window with a flyscreen. Inside the house, the couple was subjected to a violent attack. Irma Pelazic sustained fatal injuries to her face, head, and abdomen, which led to her death. Her husband, Gregor Pelazic, miraculously survived the assault but was left with severe injuries after losing consciousness during the struggle with the intruders.
The investigation centered around the traces left by the perpetrators in the home. Police found crucial DNA evidence on everyday items that the suspects had touched. A milk carton in the kitchen bore DNA from the suspect Fbritzy, while a watering can contained traces from Vicone. Additionally, technicians secured a footprint from a Reebok shoe in the kitchen as well as fingerprints on the cut flyscreen, placing the two men directly at the crime scene.
Timeline of the case
The investigation and subsequent trial have been marked by complex analyses of blood spatter and autopsy reports. The episode documents how forensic experts have reconstructed the last minutes of Irma Pelazic's life to counter the defense's theory of the sequence of events. Throughout the process, the defense has attempted to cast doubt on whether the two men acted in concert or if there was an escalation for which they could not both be held accountable.
