Childhood friends Sarah Stern and Liam McAtasney's friendship took a dark turn in December 2016 when Sarah went missing, her car abandoned on a bridge. Unbeknownst to her, McAtasney harbored a greed-driven plan, strangling her, stealing money her mother left her from a lockbox, and disposing of her body with the help of another friend, Preston Taylor. McAtasney's motive was purely financial, revealed when a filmmaker, and friend Anthony Curry, captured a secret recording of his confession. McAtasney received a life sentence without parole, plus additional time for desecrating human remains, while Taylor was sentenced to 18 years in prison.
