Chemmani Mass Graves: Excavation and Justice Update (August 15-31, 2025)

Unburying the Past: 

Editor's Note

Throughout the reporting period, editorial decisions for this document have been made in accordance with international best practices for sensitive, survivor-centered reporting on mass grave discoveries and ongoing investigations. Recognizing Chemmani’s status as both a site of lived trauma and active inquiry into gross human rights violations, this report consciously avoids sensationalism, prioritizing accuracy, legal and forensic specificity, and empathy toward victims’ families.

The assembling of this report involved special care to:

·       Include diverse perspectives: By integrating government, international, civil society, family, and survivor accounts;

·       Respect survivor and witness confidentiality: Avoiding identification or quoting of sources unless explicitly cleared;

·       Uphold journalistic and human rights reporting ethics: Following guidance from the UN Office of the High Commissioner for Human Rights (OHCHR), the Minnesota Protocol, relevant Sri Lankan law, and major media codes of practice34;

·       Provide context without editorializing or inflaming divisions: Sensitive paraphrasing was prioritized over emotive or potentially divisive language;

·       Avoid graphic images without warning and only upon editorial clearance;

·       Cross-check facts against court orders, legal protocols, and judgments to ensure accuracy;

·       Attribute all contributions and photographs from the field.

Media coverage of Chemmani remains uneven; for national healing and accountability, fact-based, balanced, and inclusive reporting is essential. Editorial rigor focused on the urgent need for national and international accountability, public truth-telling, and a respectful, rights-driven narrative for all communities affected by the conflict5.

Chemmani Mass Graves Reveal New Truths

Excavation and Justice Update (August 15-31, 2025)

Introduction

The Chemmani mass graves in Jaffna, Sri Lanka, have long cast a haunting shadow over the island’s post-war struggle with justice, memory, and accountability. The renewed excavation efforts between August 15 and August 31, 2025, mark a critical chapter not just in forensic and legal investigation, but also in Sri Lanka’s complex journey toward truth, reconciliation, and redress for victims of its decades-long conflict. This period witnessed a pronounced intensification of excavation activities, forensic analysis, judicial proceedings, government, and United Nations (UN) engagement, and a swelling groundswell of advocacy and public reaction both locally and internationally.

This comprehensive report examines the developments in Chemmani during this fortnight-including new skeletal discoveries, forensic and technological advances, courtroom and legal milestones, statements and interventions by the Sri Lankan government and the UN, and a textured account of public, familial, and media responses. The events are analyzed not in isolation, but as part of broader patterns of impunity, resistance, and hope that have shaped Sri Lanka’s handling of enforced disappearances and mass atrocity crimes.

The report draws from a vast array of web sources, eyewitness accounts, legal filings, media reports, academic analyses, and official statements, ensuring a multifaceted, evidence-based, and thoroughly referenced account of this pivotal period.

Discoveries (August 15-31, 2025)

Newly Discovered Skeletons and Excavation Progress

As of August 6, 2025, excavations at the Chemmani mass grave-situated in the Siththupaththi Hindu Cemetery, Jaffna-had uncovered a total of 147 skeletons, a number that includes at least 19 infants and children. The intense and painstaking recovery process, utilizing strictly manual excavation tools and protocols dictated by both international best practice and local judicial oversight, was temporarily paused on August 6 owing to the exhaustion of the multidisciplinary forensic team. The pause was initially scheduled to last through August 221.

The skeletal remains were exhumed from two main excavation pits: an eastern pit-where a coffin wrapped in polythene was found and flagged as a legal burial by the forensic team, and the larger western pit-where clusters of bodies, sometimes buried together with bones tangled in layers, were found. The western pit alone yielded more than 140 remains within a trench approximately 20 meters long and between two and three feet deep2.

On August 26, upon the resumption of excavation after an 18-day break, an additional 16 skeletons were unearthed, including those likely belonging to young children. By the evening of August 26, the total number of skeletons discovered had risen to 166, solidifying Chemmani’s status as the second largest mass grave ever uncovered in Sri Lanka-surpassed only by the Mannar ‘Sathosa’ mass grave3.

Artifacts such as a child’s school bag, a baby’s feeding bottle, bangles, coins, sandals, and fragments of clothing-some retrieved in clusters-added both evidentiary value and a layer of poignant tragedy to the discoveries. However, despite rigorous cataloguing and public display events, none were immediately matched to victims’ families24.

The discoveries serve to confirm much of the original testimony by Lance Corporal Somaratne Rajapakse, who in 1998 alleged the existence of mass burials conducted under military orders during the recapture of Jaffna in the mid-1990s5.

The depth, density, and character of the graves-including the commingling of child and adult remains, and the signs of hasty and violent burial-underscore the magnitude and gravity of the crimes under investigation.

Forensic Analysis

Forensic Methodology and Technological Advances

The excavation process adhered strictly to court-ordered protocols and international standards, notably the Minnesota Protocol on the Investigation of Extra-Legal, Arbitrary, and Summary Executions, and the Bournemouth Protocol on Mass Grave Protection4. Each day at the site involved meticulous work: discovering remains, separating and identifying individual skeletons, and exhuming remains under constant documentation and security measures-six CCTV cameras, floodlights, and 24/7 police surveillance at the site.

Forensic teams, including the Judicial Medical Officer (JMO), Forensic Medical Officer, scene-of-crime officers, and academic experts, employed a combination of manual excavation, stratigraphic analysis, and in situ artifact cataloguing to minimize the risk of evidence contamination.2

Ground-Penetrating Radar (GPR) and Soil Analysis:

Ground-Penetrating Radar scans were conducted by the Faculty of Technology, University of Sri Jayewardenepura, starting August 4. By August 5, approximately 20% of the cemetery’s area had been scanned, with key findings reported to the court and further scanning scheduled for the following weeks and into September1. The scans identified additional suspicious burial zones, guiding subsequent excavation.

Soil and trauma analysis, presented as part of a trio of critical forensic outputs to the Jaffna Magistrate’s Court on August 14, revealed:

·       Hurried and traumatized burial: Bodies found in unnatural postures, sometimes “bent,” and clustered in ways consistent with mass and possibly summary executions.

·       Spatial differentiation: Clear distinction between legal cremation plots (eastern sector) and areas of illicit burial (western sector).

·       Fragments of physical violence: Broken bones, trauma indicators, and signs of violence were recorded-highlighted both in site diaries and forensic reports42.

Artifacts and Family Identification:

On August 5, clothing, jewelry, toys, school bags, sandals, coins, bangles, and a baby’s milk bottle were presented for judicially mandated family viewing. More than 200 relatives attended, but no positive identifications could be made. The difficulty stemmed from the deterioration of textiles and items, and the lack of systematic pre-disappearance documentation for most missing persons45.

DNA and Remains Storage:

All excavated remains are being safeguarded at the University of Jaffna’s forensic unit, awaiting DNA assays and possible international advisory review. Legal and expert observers have highlighted the absence of a robust national DNA database as a major obstacle to positive identification-a concern that has attracted calls for international forensic partnerships and technical assistance67.

Legal Developments

Jaffna Magistrate’s Court Proceedings

All excavation and examination activities operated under the full authority of the Jaffna Magistrate’s Court, ensuring court-mandated transparency and oversight. On August 14, the court convened a key hearing to review interim forensic findings, soil, and GPR analysis, and to hear from lawyers representing affected families and organizations such as the Office on Missing Persons (OMP) and the Human Rights Commission of Sri Lanka (HRCSL)2.

Key legal milestones included:

·       Court-ordered artifacts display: As previously noted, relatives of the disappeared were invited under controlled conditions to inspect personal items for potential identification.

·       Consolidation of Investigations: Victim advocacy teams and Tamil civil society pressed strongly for the consolidation of the 1999 and 2025 Chemmani exhumations into a single legal and forensic inquiry, citing the risk of fragmented or diluted justice in parallel proceedings. Letters from MPs and legal organizations reiterated requests for international legal peer review and accountability, particularly for command-level perpetrators6.

·       Custody and Safekeeping: The court ordered that all remains, and forensic evidence be stored safely at Jaffna University, under constant judicial supervision, pending full-scale DNA analysis and any international review deemed necessary.

No new positive identifications were recorded in this period-a consequence of both forensic complexity and the limitations of Sri Lanka’s identification infrastructure. Nonetheless, the court repeatedly emphasized the priority of scientific and legal rigor over expediency.

High-Profile Legal and Political Incidents

Late August saw a dramatic escalation of legal and political tensions across Sri Lanka, paralleling the Chemmani developments:

·       Arrest of Former President Ranil Wickremesinghe: The late August arrest of former President Wickremesinghe for alleged misuse of state funds, while not directly connected to Chemmani, was seized upon by critics as indicative of selective justice and political targeting under the current AKD-led National People’s Power (NPP) government.

·       Continuation of Prosecutions: A former navy commander implicated in past abuses was also arrested, with the President and Parliament defending the necessity of such actions to strengthen the rule of law and demonstrate commitment to justice-thereby seeking to bolster public trust in ongoing investigations, including Chemmani10.

These legal developments, while not entirely linear or universally lauded, underscored a landscape in flux: for some, evidence of overdue accountability; for others, a warning about politicized or uneven application of justice.

Government and UN Statements

Sri Lankan Government Responses

Multiple statements were issued by government officials during this reporting period:

·       Justice Ministry (August 11): Cabinet spokesperson Nalinda Jayatissa reaffirmed the government’s commitment to transparency in the Chemmani process and indicated readiness for additional resource allocations should the forensic team request them. He emphasized that HRCSL and OMP oversight, along with judicial supervision, served as guarantees of process integrity. However, he stopped short of approving international forensic engagement or case consolidation with earlier proceedings6.

·       Parliamentary Pledges: Leader of the House Bimal Rathnayake, referencing UN High Commissioner Volker Türk’s recent visit, echoed government determination to “not shield perpetrators” but likewise avoided a categorical pledge for external legal or forensic review.

Most notably, on August 24, Foreign Minister Vijitha Herath announced in Parliament that the controversial Prevention of Terrorism Act (PTA) would be abolished by September. He insisted that this decision stemmed from domestic reform commitments and not external (UN or diplomatic) pressure, and that recent arrests under the PTA were overwhelmingly of Sinhalese suspects linked to organized crime-not minorities-despite criticism from activists and observers10.

Government spokespersons, including President Anura Kumara Dissanayake, asserted that Sri Lanka’s judiciary now enjoyed sufficient independence and capacity to address politically motivated abuses-encompassing not just Chemmani, but a broader swath of conflict-era crimes and ongoing systemic issues.

UNHRC, OHCHR, and International Calls

The UN and international legal bodies closely monitored Chemmani throughout August:

·       International Commission of Jurists (ICJ): On August 13, the ICJ issued a seven-point statement demanding rigorous adherence to the Minnesota Protocol, involvement of international forensic experts, unmistakable evidence protection measures, and the creation of a Special Office for serious crimes to investigate and prosecute state officials. ICJ experts stated that “only international oversight would ensure credibility given Sri Lanka’s history of impunity”11.

·       UN Human Rights High Commissioner Volker Türk: While Türk’s official country visit to the Chemmani site had occurred in June, his June and August statements remained highly relevant. He consistently called for investigations that not only exhumed bodies, but extended to “those higher up the chain of command,” and for transparent, victim-centered processes fully consistent with international obligations12.

·       UNHRC 60th Session (September-October 2025): The Chemmani case was flagged as an emblematic focal point for accountability in Sri Lanka during upcoming deliberations on the extension of the Office of the High Commissioner for Human Rights (OHCHR) mandate and the Sri Lanka Accountability Project (Resolution 46/1)7.

·       UK and Canada: International diplomatic pressure intensified, with parliamentarians-such as from the UK’s All-Party Parliamentary Group for Tamils-explicitly urging that Chemmani’s evidence be collected, consolidated, and preserved under international scrutiny.

Public and Media Reactions

Domestic Reactions

Family and Civil Society Engagement

·       Over 200 relatives attended artifact identification events on August 5, but left without closure as no personal items were conclusively matched to missing loved ones. The event was marked by grief, exhaustion, and an unyielding insistence on scientific identification and dignified return of remains13.

·       Tamil families, activists, and political organizations-especially the Ilankai Thamil Arasuk Katchi (ITAK)-demanded:

o   Full consolidation of all Chemmani cases under one legal-judicial transaction,

o   Immediate publication of forensic and DNA findings,

o   International forensic participation and oversight,

o   Prosecution of commanding officers, not just lower-level perpetrators,

o   The repatriation of remains from the 1999 exhumation in Glasgow for reinvestigation and proper burial6.

·       Memorialization and advocacy: Vigils and commemorations were organized around the International Day of the Victims of Enforced Disappearance (August 30), with calls for a formal memorial park and the documentation of the names of the disappeared6.

Media and Social Media

Media coverage-especially in Tamil- and English-language outlets-was intensive, focusing on:

·       Renewed testimony by Somaratna Rajapakse: Now reiterating willingness to testify internationally under witness protection, claiming to act under orders from superiors, particularly Captain Lalith Hewage. His statements continue to polarize public opinion, serving as both catalyst for demands for accountability and as fuel for skepticism and political pushback.6

·       Social Media Divides:

o   Tamil-language platforms: Centered on historical validation, grievances, and the call for international justice.

o   Sinhala-language discourse: Commonly focused on LTTE culpability and skepticism towards whistleblower motives, sometimes framing the excavations as foreign-instigated campaigns to undermine the military6.

·       Journalist intimidation: Kanapathipillai Kumanan, a local journalist documenting Chemmani developments, was summoned by the Terrorism Investigation Division (TID) on August 17, highlighting both the continued use of repressive PTA powers and the fraught environment for media and civil society actors in the North and East10.

International Coverage and Analysis

Global media, diplomatic, and diaspora interest in Chemmani intensified:

·       European and Canadian outlets foregrounded Chemmani as a test case for Sri Lanka’s transitional justice commitments and the credibility of its new administration.

·       International legal and academic experts-citing examples from Argentina, Bosnia, and Guatemala-emphasized the necessity of multidisciplinary, internationally observable truth-seeking and memorialization strategies7.

·       ICJ and OHCHR statements were widely cited by advocacy groups pressing for UN accountability measures and technical expertise deployment.

Implications for Transitional Justice and Accountability

The excavation and associated investigations were broadly seen as a unique-potentially last-opportunity for Sri Lanka to break a cycle of impunity surrounding enforced disappearances and atrocity crimes. The Chemmani case:

·       Reinforced long-standing mistrust in domestic forensic and judicial institutions, prompting survivors and affected communities to insist upon international engagement.

·       Reopened wounds and revived debates over the root causes and legacies of ethnic conflict, complicating national narratives of reconciliation.

·       Paralleled both modest advancements (abolition of the PTA, prosecution of senior officials) and pitfalls (intimidation of journalists, lack of transparency, stalling on comprehensive legal reforms) in Sri Lankan democratic culture.

Conclusion: Towards Justice and Truth or Another Cycle of Denial?

The events at Chemmani between August 15-31, 2025, represent both a culmination of decades-long advocacy for truth and an inflection point for Sri Lanka’s accountability trajectory. The progress-seen in the scale and transparency of excavation, technological and forensic advances, and unprecedented national and international observation-is substantial.

Yet, profound, and unresolved challenges persist:

·       No positive identifications have yet been made, and many families remain in agonizing uncertainty.

·       , notably the absence of a national DNA database and limited local laboratories, threaten identification and dignified return of remains.

·       , despite stronger judicial oversight, face demands for consolidation, speed, and internationalization to overcome both past fragmentation and political interference.

·        have been mixed-balancing pledges of transparency and process integrity with reluctance to accept international scrutiny as well as criticism for ongoing intimidation of journalists and activists under laws like the PTA (even as repeal is announced).

·       -through the ICJ, OHCHR, UNHRC, and international parliamentary groups-remains essential not only for the Chemmani case, but for wider patterns of reconciliation, reparations, and guarantees of non-repetition.

The excavation’s trajectory now hinges on whether Sri Lanka can deliver meaningful justice-by following the evidence, prosecuting command-level responsibility, memorializing victims with dignity, and restoring trust through credible, inclusive processes that center survivors. Chemmani is more than an archaeological or forensic exercise; it is a mirror to Sri Lanka’s willingness to reckon with its past in pursuit of a genuinely shared future.

If the momentum of these excavations can be translated into sustained judicial, policy, and social action-combining the strengths of national and international expertise-the ground broken in Chemmani may yet become fertile soil for truth, healing, and justice. Otherwise, it risks reinforcing a pattern of denial and impunity, with costs not only for those buried, but for a nation’s ongoing struggle with its own history.
