A 60-year-old woman was brutally murdered in her home in Kecamatan Rumbai, Pekanbaru, Riau, in a crime orchestrated by her own son-in-law. The victim, identified as Dumaris Deniwati Boru Sitio, was discovered by her husband covered in blood on Wednesday, April 29, 2026.
Cross-Provincial Manhunt and Arrests
A joint team comprising the Resmob and Jatanras units of Polda Riau and the Satreskrim of Polresta Pekanbaru apprehended four suspects following a challenging pursuit. The perpetrators had fled the region to avoid capture, extending their flight beyond the legal jurisdiction of Polda Riau.
Police tracked the suspects to two different provinces. Two individuals were secured in Aceh Tengah, while two others were arrested in Kota Binjai, North Sumatra, at their respective hiding places. Kapolresta Pekanbaru Kombes Muharman Arta confirmed a breakthrough in the case on Saturday, May 2, 2026.
Execution and Evidence
CCTV footage captured the sequence of events, showing the suspects arriving under the guise of visiting. While the son-in-law, identified by the initials AF, masterminded the attack, another accomplice acted as the executor, striking the victim repeatedly with a wooden block until she died.
Following the murder, the perpetrators moved the victim’s body to the bathroom area. During the crime, the group stole valuable assets, including gold jewelry and cash in foreign currencies. Police stated that the majority of this evidence has since been recovered.
Motives of Resentment and Greed
During a press conference on Sunday, May 3, 2026, Kombes Muharman revealed that the primary motive for AF was resentment. The suspect claimed that while living with the victim as a son-in-law, he was frequently scolded and cursed at.
In addition to personal grievances, police identified an economic motive, noting that the perpetrators intended to seize the victim’s wealth. Kabid Humas Polda Riau Kombes Zahwani Pandra noted that while the group initially planned a robbery, they changed their minds during the process, which ultimately led to the murder.
The suspects are currently in police custody and may face severe legal penalties as the investigation continues. Future proceedings are likely to focus on the specific roles of each accomplice in the planning and execution of the crime.
