In 2021, her ex-husband accused her of plotting to murder his new wife, something Sarah denies.

But Sarah was never charged with any crimes until three weeks after Joseph's mysterious death, the detective arrested Sarah for his murder.

She has pleaded not guilty to first-degree murder.

Next week, Sarah's trial will begin, and prosecutors have announced their plans to call witnesses from her past.

Dateline Field producer Rachel White, who has crossed the country investigating Sarah's case, is here to bring us up to speed.

Hey, Rachel.

Rachel, to start, tell us about Sarah and Joseph's relationship.

Were there any signs that the relationship was in trouble?

Did Joseph want out of the relationship, too?

Were they at that point?

What was Sarah telling people in the days after he died?

My.

So then about a month after Joseph died, there's news of an arrest.

Sarah Hartsfield was killed.

Rachel, as part of Dateline's reporting on Sarah, you spoke with some husbands, a former boyfriend.

And we should mention that Sarah told Dateline she denied plotting to kill Christopher's new wife.

But tell us a little bit more about the shooting death of her former fiancé, Rachel.

His name was David Bragg.

Initially, David's death was being investigated as a homicide, but no criminal charges were ever filed against Sarah.

In fact, investigators who examined the scene said that the evidence was consistent with her story.
