Tripoli , Libya ( CNN ) -- Lockerbie bomber Abdel Basset al-Megrahi is comatose , near death and likely to take secrets of the attack on Pan Am Flight 103 to his grave . CNN found al-Megrahi under the care of his family in his palatial Tripoli villa Sunday , surviving on oxygen and an intravenous drip . The cancer-stricken former Libyan intelligence officer may be the last man alive who knows precisely who in the Libya government authorized the bombing , which killed 270 people . `` We just give him oxygen . Nobody gives us any advice , '' his son , Khaled al-Megrahi , told CNN . CNN 's Nic Robertson : 'Not what I was prepared for ' Al-Megrahi was freed from a prison in Scotland in 2009 after serving eight years of a life sentence for blowing up the Pan Am jet , killing all 259 on board and 11 in the town of Lockerbie below . Doctors who had been treating him for prostate cancer gave him just three months to live , and he was released on compassionate grounds . He received a hero 's welcome in Tripoli , enraging many in the United States and Britain . And with the recent overthrow of longtime Libyan strongman Moammar Gadhafi , politicians on both sides of the Atlantic have called for al-Megrahi to be sent back to prison . Al-Megrahi has been subject of bitter dispute .

With the fall of Tripoli to the rebels , his care has been left up to his son and his mother . December 21 , 1988 : On the scene in Lockerbie . `` There is no doctor . There is nobody to ask . We do n't have any phone line to call anybody , '' Khaled al-Megrahi said .
