This week’s “48 Hours” investigates the case of a young Texas woman who may have been murdered because she resembled the killer’s ex-girlfriend. In 2016, police discovered the body of 24-year-old college student Jackie Vandagriff the morning after she met Charles Bryant at a bar. As police investigated, they learned Bryant had been stalking another woman, his ex-girlfriend Caitlin Mathis, and that Vandagriff may have been targeted because of her likeness to his ex. Mathis spoke to CBS News senior national correspondent Jim Axelrod in her first television interview, and Axelrod joined CBSN to discuss the case. Source
