At a minimum I think she was reckless. You couldnt let her off completely. First degree murder seems excessive for this and so does the sentence. But I doubt shell serve the full sentence. Will probably eventually have the charges downgraded.
She admitted on the stand she was going to kill whomever was in that apt. On the 911 call her primary concern was she was going to lose her job. And she did a little cpr.
It wasn’t “first degree” murder, Texas has no degree rating.
She shot an unarmed man, in his home. That’s murder.
