NO EVIDENCE OF FOUL PLAY
Zhvania's body was found at 4:30 a.m. (0130 GMT) when his guards, worried that he was not answering his mobile phone, broke down the door of the friend's apartment, said Merabishvili. The friend, a middle-ranking official, also died.
There was no evidence of foul play, forensic experts said. Tests showed Zhvania's blood contained fatal levels of a substance called carboxihaemoglobin, said Justice Ministry official Levan Samkharauli.
"That means that the cause of death was carbon monoxide gas," he said. A post mortem report is expected on Friday.
Gas poisoning is common in Georgia, mainly caused by the heaters run off gas canisters that people use in winter, when power supplies are erratic.
Wasn't Zhvania openly feuding with other ministers. Need to cross check with articles I posted earlier.
