Siak Police Reveal Cause of Death of Doctor at Tengku Rafian Regional Hospital

The Criminal Investigation Unit of the Siak Police in Riau Province has revealed the cause of death of Dr Alex Cristo Loris, an Anaesthesiology Resident from the University of Riau’s Specialist Doctor Education Programme at the Tengku Rafian Regional General Hospital (RSUD) in Siak. Siak Police Chief AKBP Sepuh Ade Irsyam Siregar stated that based on a series of scientific investigations, including an autopsy, forensic laboratory examinations, digital forensics, and forensic psychology, investigators concluded that the cause of death was due to the victim’s own actions. “Investigators from the Siak Police Criminal Investigation Unit concluded that no facts were found pointing to a criminal act of murder. The cause of death of the late Dr Alex Cristo Loris was concluded to be a result of his own actions,” Sepuh Ade Irsyam said during a press conference in Siak on Tuesday. The doctor’s body was previously found in bushes next to the fence of the Tengku Rafian Regional Hospital in Siak on Tuesday, 14 July 2026, at around 11:30 WIB. According to Sepuh Ade Irsyam, since the report of the body’s discovery was received, investigators immediately processed the crime scene, secured evidence, examined CCTV footage, took witness statements, and involved various experts to objectively and professionally determine the cause of death. From the crime scene investigation, it was determined that the victim was found lying on his back in the bushes about five metres from the outer fence of the hospital. Near the victim, a bag was found containing various medical supplies, including a stethoscope, the anaesthetic drug Propofol, Lidocaine ampoules, syringes containing Fentanyl Citrate and Rocuronium Bromide, and several hypodermic needles. Furthermore, CCTV footage obtained from two sources showed the victim walking alone towards the location on the night before he was found dead, and no other person was seen accompanying him. “The autopsy results indicated there was an injection mark on the back of the victim’s left hand, suspected to be the entry point for the Rocuronium drug into the body. Toxicological examination found Rocuronium content in the victim’s urine, blood, and kidney samples,” he revealed. Consequently, the forensic expert concluded that the victim’s death was caused by the effects of Rocuronium, which resulted in total paralysis of the respiratory muscles, leading to suffocation (asphyxia). Meanwhile, a bruise on the victim’s head was not the cause of death, and other injuries on the body were post-mortem wounds caused by insect activity. “Examination by the Riau Regional Police Forensic Laboratory also confirmed that blood spots on the syringe were identical to the victim’s DNA, indicating that the syringe was used by the victim himself and contained Rocuronium,” he said.
