(CNN) -- Once the ultimate power couple in China, Bo Xilai and his wife Gu Kailai have now vanished. Bo has been stripped of his top Communist Party posts for unspecified "serious violations of discipline," while Gu has been detained in connection with the death of Neil Heywood, a British businessman. The scandal has rocked the Chinese leadership to the core. But weeks after the shocking news of the couple's fall from grace broke, little substantiated information has come out. It has mostly been rumor and speculation. Some people at the center of the story have been silenced. Others have been locked up.
