NEW DELHI — In the series of photographs shot in 2009, the bare-chested boy is first shown seated on a bench watching something outside the frame. Then he is seen having a snack. In the third image he is lying on the ground with bullet holes in his chest. The photographs, which were released last week by the British broadcaster Channel 4, appear to document the final moments in the life of 12-year-old Balachandran Prabhakaran, the youngest son of the slain founder of the Liberation Tigers of Tamil Eelam, Velupillai Prabhakaran.
