## Resource

The episode recounts the tragic 2019 kidnapping and homicide of Heidi Broussard and the abduction of her infant daughter, Margot. The investigation reveals that Broussard’s longtime best friend, Magen Fieramusca, orchestrated a elaborate scheme to steal the child by faking her own pregnancy. After Broussard vanished from her Austin home, authorities discovered her body in the trunk of a car at Fieramusca’s residence, while the newborn was found unharmed. This narrative explores themes of pathological envy and extreme betrayal, detailing how a trusted companion weaponized a two-decade-long friendship to commit a violent crime. Ultimately, the account concludes with Fieramusca’s guilty plea and 55-year prison sentence, highlighting the devastating impact on the surviving family members.
