# Madiun murder and mutilation case > Developing situation record from CLSTR: https://clstr.news/situations/madiun-murder-and-mutilation-case > Updated: 2026-11-03T06:25:06.000Z. Sources: 20. Developments: 5. Dwi Bagus Martono was arrested in Jombang for the murder of his unofficial wife, Dini Hardiyanti, and her 4-year-old son, Arshaka Ghafa El Faezya. The victims had been missing since September 20, 2026. Investigations revealed that Martono strangled Hardiyanti in a Madiun hotel room and killed the child in a vehicle to prevent him from witnessing the act. To conceal the crimes, the suspect used a meat grinder and fire to destroy the bodies at his residence. Following his arrest, Martono issued a public apology during his transfer to the East Java Regional Police, claiming his actions were a “momentary lapse in judgment.” He admitted to dismembering the bodies with a meat chopper and attempting to dispose of the ashes in a river. During a pre-reconstruction process, Martono claimed his methods for destroying evidence were inspired by an Indian film. Martono faces charges including premeditated murder and violations of the Child Protection Act. His legal wife, Martha Amalia Iflahah, was present during reconstruction but was unaware that the killings and disposal of remains had occurred in the backyard bonsai garden. Police noted that the crime scenes were separated from the main residence by a high wall, and Martono’s habit of burning waste in the backyard did not arouse suspicion. Psychological evaluations conducted by the East Java Regional Police indicate that Martono suffers from Narcissistic Personality Disorder (NPD) characterized by an excessive sense of superiority. New forensic and digital evidence has further detailed the crime. DNA testing from the Indonesian National Police Laboratory confirmed that bone fragments found at Martono’s residence belong to the victims. Additionally, investigators discovered that Martono used a sleeping bag to transport the bodies from the hotel to his home, where he allegedly used diesel fuel and a constructed furnace to burn them. ## Claims - Dwi Bagus Martono apologized to the victims' family and the public for his actions.
