Myanmar's military rulers have without explanation ordered all legal proceedings against deposed leader Aung San Suu Kyi to be moved from a courtroom to a prison, a source familiar with her cases said on Wednesday.

A prison in Khon Kaen province has launched an investigation into how a female defendant charged with killing and dismembering a karaoke girl was able to conduct Facebook chats with an admirer and even send him photos directly from her trial.
