Carlos Lehder Rivas

I didnt know where to post this so i decided to post it here
Ive been doing my own personal reserch on the Medillen drug cartel and the main players involved, mainly carlos lehder..... I want to know if anyone has any infomation on the question of if he has been released from prison or still being held in a secret location but still in custody. Also it appears that there have been many pretenders in the past that have claimed to be the off spring of the cartel members. Does anyone have any infomation on who is telling the truth. ???

Thanks
