The case was also among those investigated by the Udalagama Commission in 2007/08, although its report has never been published. The Lessons Learnt and Reconciliation Commission recommended that the Government should complete the investigation and prosecute those responsible.

In its comments on the present report, the Government stated that a team of senior prosecutors continued to pursue various lines of inquiry, although it has not been possible to establish the identity of those responsible. 3. Executions of prisoners and those who surrendered 56. Since the end of the armed conflict in 2009, video and photographic material have emerged depicting scenes from the last phase of the war, in which prisoners appear to have been killed upon their surrender or while in the custody of the security forces. 57. In June 2011, the Special Rapporteur on extrajudicial, summary or arbitrary executions presented a technical report to the Human Rights Council that demonstrated the authenticity of portions of the video footage first broadcast by Channel 4 in August 2009.37 On 10 September 2009, the Government had announced the outcome of its own technical analysis on the basis of which it disputed the previous findings of the Special Rapporteur. In response, the Special Rapporteur commissioned independent experts to undertake a technical analysis, which confirmed his initial conclusion. While the Lessons Learnt and Reconciliation Commission did not reach a firm conclusion on the authenticity of the material, it recommended that the Government should conduct further investigations. According to the Government, this is now the subject of a second stage of proceedings by the military court of inquiry, yet to be concluded.38 (a) Balachandran Prabhakaran 58.

The photographs were taken in May 2009, a few hours apart and with the same camera. The authorities have maintained that the boy was killed in cross-fire. (b) T.
