KEY POINTS:
Phil Spector's defence will rely on an "invisible witness" to prove he did not shoot actress Lana Clarkson, one of his lawyers said: science.
Science will show that Clarkson shot herself, that music producer Spector was not standing close enough to shoot her, that his DNA was not on the gun and that his clothing bore no trace evidence to prove guilt, the defence told jurors.
Spector has pleaded not guilty to her murder.
