A third criminal trial for accused

As most readers know from high school civics class, the consitution forbids double jeopardy. In other words the government only gets one trial to take away a criminal defendant's liberty. The government gets one bite at the apple... unless the original trial ended in a mistrial. The PE reports that a Corona woman is starting her third trial. The first two ended in mistrials. The first one resulted in the jury being unable to conclude guilty or not guilty. The second occurred when the judge decided that the jurors could not be unbiased! So two prior trials, neither of which were concluded.
