SC, I don't know how close to her you are, but she should probably talk to a lawyer. In every State I know of, it is not possible to simply cut a spouse out of a will. There is something called the "elective share" and if the will cuts out the spouse, the spouse can "elect" to take the share regardless of what the will says. She should consult a lawyer who deals with family law or estate law. More than likely she is entitled to a pretty large chunk of his estate, regardless of what is in the will.
