Nabire — The Cartenz Peace Operation Task Force, in coordination with Nabire Police, conducted a reconstruction of the premeditated murder case involving two Brimob Yon C Nabire personnel, Brigadier M. Arif Maulana and Second Brigadier Nelson C. Runaki. The reconstruction took place on Tuesday (August 26, 2025) at the crime scene, located on the Trans Nabire–Enarotali Road, Siriwo District, Nabire Regency, Central Papua.
The reconstruction was led by Head of Cartenz Peace Operation Enforcement Task Force, Police Commissioner Wahyu, S.I.K., M.H., involving personnel from the combined Enforcement and Tactical Units as well as the Nabire Police. A total of 21 scenes were reenacted to depict the series of events leading to the deaths of the two Brimob officers.
One of the identified suspects, Suplianus Bagau, also known as Siprianus Weya or Supli (31), was present at the scene to demonstrate his role alongside several witnesses.
According to the reconstruction, the murder took place on Wednesday (August 13, 2025) at approximately 08:45 WIT. The perpetrators, led by Aibon Kogoya, were divided into three groups:
First Group:
- YM
- YW
- KM
Task: Carried out the shooting of Brigadier M. Arif Maulana at Crime Scene 1.
Second Group:

Task: Carried out the shooting of Second Brigadier Nelson C. Runaki at Crime Scene 2.
Third Group:

Following the shootings, the perpetrators seized the victims’ firearms — an AK-101 and an AK-47 — as well as their body vests. They also recorded a statement video at a makeshift camp, allegedly filmed by suspect Suplianus Bagau.
The reconstruction was carried out under tight security, involving 15 tactical vehicles, 24 long-barreled firearms, and complete combat gear including body vests and helmets.
Head of the Cartenz Peace Operation, Brigadier General of Police Dr. Faizal Ramadhani, S.Sos., S.I.K., M.H., emphasized that this reconstruction is a crucial step in the investigation to strengthen legal evidence.
“This reconstruction aims to verify each suspect’s role and reinforce the legal evidence in the murder case of the two Brimob officers. We ensure the legal process proceeds accordingly and transparently,” said Brig. Gen. Faizal.
He also expressed appreciation to the personnel who worked hard on the ground:
“We are committed to upholding the law and ensuring public safety. There is no place for armed groups who commit violence in Papua.”
Meanwhile, Deputy Head of the Cartenz Peace Operation, Police Commissioner Adarma Sinaga, S.I.K., M.Hum., confirmed that the reconstruction was completed without any security issues.
“The entire process went smoothly, safely, and under control. This reconstruction will serve as essential evidence to complete the case file before it is submitted to the public prosecutor,” explained Commissioner Adarma.
After the reenactment, suspect Suplianus Bagau was returned to the Nabire Police detention center. The Cartenz Peace Operation and Nabire Police investigators will finalize the case file for further legal proceedings.
“We urge the public to remain calm and support the law enforcement efforts. We will continue to pursue the other fugitives still at large,” Commissioner Adarma concluded.
