In this final episode, Kim writes from prison. Meanwhile, back where it all began, a tragic story of a young woman's death in Inverness may reveal more about him.

Karen Read is facing second-degree murder charges in connection with the death of her boyfriend, John O'Keefe.

The prosecution claims she ran over O'Keefe with her SUV, while her defense argues that he was beaten and left for dead by someone else.

O'Keefe's DNA was found on Read's broken taillight, but the defense claims evidence shows individuals inside the home where O'Keefe was left in the snow were aware he was dying before Read.

Despite gaining online support, Read's motion to dismiss the murder charge was denied, and her trial is set to begin on April 16.

A former police officer, Nicholas Tartaglione, was sentenced to four consecutive life terms for murdering four people, including Martin Luna whom he believed stole money meant for drugs.

Tartaglione kidnapped and killed three other victims who were with Luna at a club in 2016.

The bodies were found buried on Tartaglione's property in New York.

Despite maintaining his innocence, one accomplice committed suicide when FBI agents closed in, and another was sentenced to 16 years in prison.

Tartaglione's brief stint as a cellmate of Jeffery Epstein raised further attention, although he was not his cellmate at the time of Epstein's death.
