Killer Relationship with Faith Jenkins is back for a new episode, this time revolving around a murderous mother-in-law.

The third episode, “Monster-In-Law,” follows the story of Jelka Pesic, who killed her daughter-in-law Alexandra because of her son Joe. According to the logline:

Two young people are set up by their parents, leading quickly to love and marriage which is then destroyed by a deranged mother-in-law who orders the killing of a beautiful young woman in broad daylight.

The Vancouver Sun reported in 2008 that Jelka was charged and convicted of hiring a hitman to kill Alexandra, possibly as an attempt to help her son Joe gain custody of his and Alexandra’s then-three-year-old son. In the aftermath of the murder, Joe later eventually “abandoned” his son and neglected to pay child support to a number upwards of $80,000.

The exclusive clip from the episode below paints a picture of Joe as a man who was in the middle of a toxic relationship between his wife and mother, with his family withholding his payment from their family business if he did something that they didn’t like.
