In a small home in western Tamil Nadu, a 47-year-old man, seated on a chair, sips a glass of water, hoping it will stem the tears. It doesn't. His 20-year-old son, Ilavasaran, was found dead on a train track on Thursday, a day after his young wife said in court that she would never return to him. A post-mortem was done today; a video of the procedure will be shared with his inconsolable parents, a request they have made legally as questions swirl around whether the young man committed suicide.
