Madiun murder investigation: DNA confirms victims' identities

Police in Madiun have confirmed through DNA testing that bone fragments found at the residence of suspect Dwi Bagus Martono belong to the victims, Dini Hardiyanti and her four-year-old child. The forensic results from the Indonesian National Police Laboratory matched the fragments with DNA samples provided by the victims' family in Bogor.

Investigators have also uncovered digital evidence on the suspect's mobile phone, including internet search histories and WhatsApp conversations, which allegedly indicate a premeditated plan to commit the murders. According to East Java Regional Police, the digital traces suggest the intent to kill was present well before the incident occurred.

The case follows the disappearance of Dini Hardiyanti and her child on September 20, 2026. Police are currently integrating the digital evidence, forensic findings, and witness testimonies to complete the investigation into the killings.
