Judge denies Murray's bid for testing

Los Angeles - A judge has denied a request to retest a vial of the powerful anaesthetic that killed Michael Jackson.

Dr Conrad Murray's lawyer asked for testing on a vial of the anaesthetic propofol on Friday.

Superior Court Judge Michael Pastor says Murray's defence attorneys knew about the vial at the start of the case and could have requested the testing months ago.

Attorney J Michael Flanagan wrote in a court filing that the testing is necessary to analyse the prosecution theory that Murray placed Jackson on an IV drip of propofol and the painkiller lidocaine then left the room.

A prosecutor argued on Monday that Murray received a fair trial and there was no legal basis for the request.
