Killer Relationship with Faith Jenkins Season 3 description:

Faith Jenkins, former criminal prosecutor at the Manhattan District Attorney’s office, explores the heart stopping details of murders traced back to romantic liaisons and close friendships that seemed perfect on the surface.  Stories investigated this season include a beloved second grade teacher who goes missing just as she’s embarking on a new chapter in her life; a former DEA agent found dead  after living a quiet life in the Florida Keys; a Korean War veteran whose murder unveils a tangled web of secrets and betrayal and a mother who vanishes on her way home from a prenatal yoga class. 

The real-life Jacquelyn Smith murder case

As CBS News reported, Keith was found guilty and sentenced to life in prison for the murder of his wife and his attempt to cover it up.

“This didn’t bring her back but we were elated and feel that definitely justice was served,” said Jacquelyn’s sister, Yvonne Saab, at sentencing. “And as I said on the record, the judge was very poignant and to the point. You could tell that she really reviewed this case thoroughly and made a decision that made us very happy.”
