Summary According to the findings of this report, the day following the discovery of the campsite, a senior police officer ordered the compound destroyed, thus diminishing potential physical evidence that might have aided a police investigation. Moreover, the authorities did not publicly reveal any information about the site until May 25, 2015, more than four months after the initial discovery of the campsite and mass graves. A forensic team also confirmed on March 6, 2015 that the suspected gravesite was indeed a mass grave, but Malaysian authorities did not order the exhumation of the bodies until May 2015. Forensic specialists testified for this report that their post-mortem examinations of the remains exhumed from the site were inconclusive with regard to the cause of death due to excessive decomposition of the bodies. The four-month delay in investigating the gravesite delayed the exhumation of remains from the site, which, in turn, hampered forensic specialists from identifying the causes of their death. This may constitute obstruction of justice. Chapter IV of this report focuses on eyewitness testimony suggesting official complicity or direct involvement of government officials in the mass human trafficking that took place from 2012 to 2015 from Myanmar and Bangladesh to Thailand and Malaysia. Eyewitness testimonies build on information established in human-trafficking trials in Thailand and indicate the complicity or, in some cases, direct involvement of government authorities in this complex criminal syndicate. Survivors’ testimonies in this report reveal that Thai authorities extrajudicially transferred Rohingya from state custody to traffickers and, in some cases, to humantrafficking camps on the Malaysia-Thailand border or in Malaysian territory. According to survivors, Thai authorities sold Rohingya in their custody to traffickers and were directly involved in the trade of Rohingya. Further investigation is required to determine the extent Malaysian authorities were responsible or involved in the trafficking of Rohingya and Bangladeshis from 2012 to 2015. However, available evidence indicates the authorities in Malaysia and Thailand have not investigated or held perpetrators to account for the full extent of the crimes related to the trafficking of Rohingya and Bangladeshis.
