No, that's not one of the other crimes that will make this capital murder.
IMO, their best bet is to add kinapping (which is exactly what she did) - that will make it capital murder.

Okay, let me first state that this woman is the lowest scum on the face of the earth.
Having said that, in my legal opinion, this isn't going to be prosecuted as a capital murder. You can argue that the victim was being kept against his will, and that amounted to a kidnapping, in order to qualify as capital murder, but it's not going to fly.
There certainly was no intent to kidnap this person at the time of the accident, and there's little doubt that she would have left him on the road if he hadn't stuck in her windshield. After she got home, she made no effort to prevent his escape, not that he could, of course. But it's pretty evident that she didn't want to kidnap the guy. She just didn't want to deal with the situation.
She deserves the maximum punishment under the murder statute, but bumping it up to capital murder is going to be a tough sell, and I don't think it will happen.
