Final hours of Prabha

The official story, that Prabhakaran was shot somehow and then soldiers finding his body in a lagoon while media been able cover that exact moment live sound like a fairy to me. Army chief keep insisting that Prabhakaran was killed even before his body was found was also suspicious. I think Prabhakran was captured through a surprise commando type attack or a gas attack and then executed. Is the body of Pottu Amman found? If not it would also surface from some lagoon after some time I guess.
