Nidal, your character is a homicide detective

Donald, The Police Detective 

Nidal, your character is the man who around 1980 conducted the initial investigation of the disappearance of Russell, Indigo Milazzo's husband. Mrs. Milazzo, the very attractive orphaned daughter & only child of the wealthiest family in town - the family's matriarch founded the town of Flavia, Nebraska. The town is named after Flavia.

When Indigo reports her husband Russell, who she has just married has disappeared, abandoned her, the townspeople find it hard to believe because Russell was a respected businessman who got his start as a disadvantaged child of poor, unlucky farmers, who Indigo's father took under his wing, educated him and set him up in business - Indigo grew up with Russell as sort of a 10-years older brother. But Indigo lost her parents in a plane crash just six months prior to her wedding and the townspeople are extremely sympathetic and so they believe her, and noone in town would badmouth her or her family anyway, because over half of them would not have a job if not for the Milazzos. 

But you, Donald, don't believe Russell abandoned Indigo. You persist in questioning her until she complains to your supervisor. Your supervisor tells you to close the file. But then, 8 months after the disappearance of Russell, a woman (Becky) comes to see you because she read about your investigation in the paper. She tells you that she was Russell's mistress, they have 3 children, he bought her a house, supported her and his children and regularly visited them, trying to keep her position in the community as respectable as possible under the circumstances. 

So you convince your superiors to get the file reopened and you start visiting Indigo every day - questioning her, poking around all the structures on her property, digging in her garden. She is more friendly this time around and starts feeding your breakfast when you show up in the morning. She is sometimes flirtatious (you are the actor: it's your call how you handle Indigo being friendly, as you are about 30 older now but you are a cop, professional and might have had a girlfriend, etc., in those days.)  

One day in the spring, a humid day when the very large compost heap in her backyard is particularly stinky, you realize that is the one place you haven't searched. It's messy, but you start poking around it and find this bone and you know that it's from the hand of a large human - Russell's size. You take it to the lab (you are the actor: it's your choice whether you tell Indigo that you found it.) Sure enough, the lab confirms that it's Russell. 

Just so you know, if the lab used DNA testing it would have to be 1985. So you can decide whether your investigation was around 1985 or before. We can adjust the dates in the movie if you decide the lab used DNA testing. Now you have to arrest Indigo, the pretty lady who has become your friend. How you do it is up to you the actor. However, once Indigo's arrested, she becomes very angry (understandable!) and she tells you that the ham she's been feeding you with your eggs came from Russell, because she cut him up, cured him and hung him in her meat cellar. That disgusts and hurts you, but when the lab tests the ham, they confirm that it's Russell ham. 

Now it's 30 years later and you're the chief law enforcement officer of Cheyenne County; and every time there's a hearing about releasing Indigo, you show up to testify against her ever getting out of the prison for the mentally ill.
