That would be true only if he survived the ordeal. However, he didn't, so this is more likely second-degree murder.
She's a nurse's assistant and she refused to give him aid over a two-day period? I'd argue that constitutes premeditation and malice aforethought with respect to anything that occurred after she drove home and sobered up...and I bet I could convince a jury to agree with me. At the least it is a depraved heart murder, but I think there is a strong argument for First Degree murder since she failed to render aid to him and had to know the eventual results of her deliberate inaction.
I don't necessarily disagree with that, but whatever they finally charge her with there still has to be intent.
Without intent, mens rea, there cannot be a crime.
