Chemmani’s Interim Report Raises Competing Explanations. Evidence — Not Narrative — Must Decide

An interim archaeological report has reopened argument over how hundreds of people came to be buried at Chemmani. The responsible response is neither to declare the case solved nor to dismiss inconvenient evidence. It is to test competing hypotheses through transparent, multidisciplinary forensic work.

Reporting on an interim archaeological summary submitted in October says the excavation team raised possibilities including epidemic or natural-disaster burial while acknowledging that the available evidence did not establish how the dead came to be at the site. Other reporting has challenged that interpretation, pointing to features including the condition, depth and proximity of remains and evidence previously considered by Sri Lanka’s Human Rights Commission.

These competing interpretations must not be converted into premature conclusions. An archaeological hypothesis is not a criminal-court finding. Nor does criticism of that hypothesis prove that every person recovered was unlawfully killed. The central fact is that hundreds of human remains have been recovered and their identities, causes and circumstances of death require rigorous investigation.

The Human Rights Commission reached a different concern

After a 2025 visit, the Human Rights Commission said features including shallow burials, lack of clothing and the close proximity of some remains created a reasonable likelihood that burials were unlawful and associated with extrajudicial killings. That assessment is significant, but it too must be tested against the full forensic record rather than treated as a substitute for individual identification and cause-of-death analysis.

Human Rights Watch reported in September 2026 that 582 remains had been recovered and warned that excavation by itself does not deliver justice. The number has subsequently been reported as higher. The exact running total matters less than the institutional obligation now created by the scale of the site.

What a credible next phase requires

The court-supervised process should publish, where legally possible, a clear forensic protocol covering mapping, exhumation records, chain of custody, pathology, anthropology, DNA sampling and comparison with relatives. Competing explanations should be expressed as testable hypotheses with the evidence for and against each one identified.

Independent peer review would strengthen rather than weaken the domestic process. International forensic specialists can assist without deciding criminal responsibility. Families should receive regular information through a structured liaison mechanism and should be able to nominate or consult independent experts where the court permits.

Do not let a scientific disagreement become a political shortcut

Sri Lanka’s history makes Chemmani politically charged. That is precisely why scientific language must be disciplined. Terms such as “mass grave”, “formal burial”, “epidemic” or “extrajudicial killing” carry enormous implications. They should follow evidence, not political preference.

Lanka Witness assessment: The interim report should trigger more forensic testing, not an early closing narrative. The state’s duty is to identify the dead where possible, establish cause and manner of death, preserve evidence, test every credible hypothesis and allow a court — not politics — to determine what the evidence proves.
