I have a test where I am given the following article, what is an answer for the question: Who gets away with extortion and murder? ?

Rosa Moline is the dissatisfied, restless wife of Lewis, a small-town Wisconsin doctor. She is easily bored, uninterested in her husband's career or in anything to do with her current circumstances. She has long desired a glamorous life, in a world where she can have expensive things and meet truly interesting people. For over a year, she has been having an affair with Neil Latimer, a Chicago businessman who owns the local hunting lodge. Tired of waiting for him to ask her to marry and move to Chicago, Rosa extorts money from Lewis' patients - who often do not have cash but pay him in produce or in other non-financial ways - to finance her trip to the city.
Lewis does not yet know about the affair, but he is used to his wife's unease with her life; he discovers the extortion and throws the cash at her, telling her that if she goes to Chicago, she need not come back. Rosa immediately leaves and fully expects Latimer to welcome her. However, he avoids her at first, then when he does meet her, he tells her he is love with another woman and intends to marry. Devastated, Rosa returns to Wisconsin, where Lewis forgives her. She soon becomes pregnant and, briefly, seems to be trying to settle down.
During a party for Moose, the man who tends to the hunting lodge, Latimer shows up. He lets Rosa know that he has changed his mind and wants to marry her. Moose overhears the couple planning for her divorce and their marriage; the next day, as everyone is heading out on a hunting trip, Moose bets that her lover will not want the baby and advises Rosa that she had better tell Latimer about it, or he will. To prevent that eventuality, she shoots and kills Moose during the hunt. She is acquitted of this act by claiming she thought he was a deer.
