What happens next? [Spoiler]
So does anybody think she will get away with murder? It would appear she got away with the perfect crime, but eventually the police will start probing as he turns up missing.
My other question is why not just divorce, have the "sister" go away and disappear, and collect alimony? If I'm correct, she didn't work or at least wasn't bringing in much of an income. Depending on the state, she won't be able to collect any life insurance if his body isn't found, and would have to wait several years for him to be declared dead.
BTW, in this day and age, I wouldn't think an employer would hold it against someone or not give a promotion because they got a divorce.
