Prosecutors in Park City, Utah, begin laying out their case that Corey Richens poisoned her husband and father of her children, Eric, with a lethal dose of fentanyl in 2022.

She later self-published a children's book on grieving following his death.

She's pled not guilty.

The trial is set to last up to five weeks.

Her lawyers say Richens has waited nearly three years for the facts of this case to be heard by a jury.

Free from the prosecution's narrative that's dominated headlines since her arrest.
