I saw a TX Defense Attorney on O'Reilly say that Texas law allows for a guilty verdict and a finding for "an Act of Passion" or some similar nomenclature, that will allow for a greatly reduced sentence. she cited a case in Houston where a fellow killed his wife and her lover (shot them and left them alive, came back later and finished them off) and he got 10 months probabtion. I wouldn't be surprised if Harris gets something along these lines. A guilty verdict for First Degree murder wouldn't necessarily be bad news for her. Heck...his parents by their testimony in her favor gave the jury permission to be as lenient as they'd like.
She went around three times. Passion for what, NASCAR?
This is not a death case because it does not qualify for any of the statutory circumstances which give rise to capital murder.
Regardless whether the jury finds sudden passion or not, she is still elgible for community supervision. However, it is unlikely that she would receive community supervision if the jury does not find that she acted in sudden passion.
