Madiun murder suspect Dwi Bagus Martono accused of killing wife and child

Dwi Bagus Martono, a freelance offshore oil engineer, has been named a suspect in the murder and mutilation of his second wife, Dini Hardiyanti, and their four-year-old child in Madiun, East Java.

According to his legal wife, Martha Amalia Iflahah, Martono confessed to having a secret marriage for the past two years during a conversation on October 10, 2026. At that time, he claimed the second wife and child were missing. Investigators have since determined that the child, AGF, was executed in the living room of the suspect's parents' house before the body was moved and burned on October 22, 2026.

Martono was arrested in Jombang after a 15-day disappearance. The investigation revealed that the suspect had previously reported the second wife as a missing person to the Madiun City Police on October 5, 2026, while instructing his lawyer not to inform his first wife of the situation.
