Closing arguments are scheduled to begin Monday in the murder trial of Kouri Richins, a Utah woman accused of fatally poisoning her husband with fentanyl four years ago.

Richins is charged with giving her husband a deadly dose of fentanyl in 2020. Following his death, she published a children's book focused on grief, which has become a central element in the prosecution's case against her.

The trial has included 13 days of testimony from witnesses called by the prosecution. The defense team did not present any witnesses during the proceedings.

If convicted on the murder charges, Richins faces the possibility of life in prison. The case has drawn attention due to the unusual circumstances involving the children's book published after the alleged crime.

The trial represents the culmination of a years-long investigation into the death, with prosecutors alleging that Richins deliberately administered the fatal dose of fentanyl to her husband before later writing about the experience of loss in her published work.
