Evidence for
The Kanjuruhan Tear-Gas Deployment and the Split Accountability Case

Companion notes

Kanjuruhan Stadium disaster and the police tear-gas investigation

The public record shows a fatal crowd crush at Kanjuruhan Stadium on 1 October 2022, followed by criminal, disciplinary, and forensic scrutiny of police conduct and organizer decisions. Across court coverage, human-rights findings, and autopsy reporting, the documentary trail establishes tear-gas deployment, a 135-death toll, and a contested accountability process that produced mixed outcomes for police and match officials.

The Paper Trail & Official Records

The documentary record begins with contemporary reporting and later court coverage that align on the central facts: the Arema–Persebaya Surabaya match at Kanjuruhan Stadium ended on 1 October 2022, then a crowd crush unfolded in Malang Regency, East Java. Public accounts published by the Associated Press-style sports reporting in The Jakarta Post and later court reporting in The Independent describe a disaster that killed 135 people, while reference summaries and police-facing coverage record the same death toll and location. Those materials are not equivalent to a full evidence dossier, but they do establish the factual baseline used by investigators and prosecutors. [S1], [S3], [S5]

The paper trail also includes official procedural steps. Police announced six suspects on 6 October 2022, and the case later moved into the Surabaya District Court, where police officers and organizers were charged with negligence. Reporting in Kompas and The Jakarta Post ties the criminal case to the broader accountability process, while The Independent tracks the court outcomes. Taken together, these records show a staged response: immediate suspicion, formal charging, and then adversarial testing before a criminal bench rather than a single administrative finding.

Forensic Chronology & Turning Points

The chronology is most important because it links actions to consequences. All major non-Wikipedia reports agree that police fired tear gas during the stadium aftermath, and that deployment is repeatedly placed before the crowd surge and crush. The National Human Rights Commission’s investigative conclusion, as summarized in The Jakarta Post and The Independent, was that police fired tear gas into the crowd and that excessive, indiscriminate use of it was the main trigger behind the stampede. That conclusion matters as a documented institutional finding, even though it is not the same as a criminal conviction. [S3], [S5], [S4]

Two later turning points sharpen the forensic picture. First, on 10 October 2022 police acknowledged expired tear gas had been used, adding a material detail to the weaponization and inventory questions surrounding crowd control. Second, a BBC News Indonesia report on exhumations and independent autopsies shows that families sought laboratory-based confirmation of injuries and causes of death, illustrating how forensic work became part of the public truth-seeking process. Those autopsies did not simply repeat the event narrative; they represented an attempt to test it medically and independently. [S2], [S5]

Evidentiary Boundaries & Negative Findings

The strongest evidentiary boundary is that the record supports tear-gas use and a fatal crush, but not a single-cause explanation that excludes other failures. The sources show police conduct, crowd conditions, stadium management, and organizer responsibilities moving together through the case, yet they do not reduce the disaster to one actor alone. The human-rights conclusion about tear gas as the main trigger is important, but it remains one institutional account within a broader process that also tested negligence by organizers and police command decisions. [S3], [S5], [S1]

Court outcomes further limit what can be claimed as settled. The Independent reported that the Surabaya District Court acquitted police officers Wahyu Setyo Pranoto and Bambang Sidik Achmadi, while convicting Hasdarmawan of criminal negligence causing death and bodily harm. That split result shows that accountability was neither uniform nor final at the trial level, and it underscores why later appellate developments matter. The autopsy reporting likewise draws a line between family expectations and proof: the BBC account does not confirm the hoped-for detection of tear-gas residue in the exhumed bodies, so that allegation remains unproven in the cited medical coverage.
