This history made Bryant a good suspect for Jackie Vandagriff's murder, but police didn't have enough evidence to arrest him right away. She had also filed a restraining order against him. In the weeks leading up to Jackie's death, Bryant kept showing up on Caitlin's campus in Denton and was arrested three times. 'He was just trying to win me back and I was just like, nothing is going to work,' she told CBS News correspondent Jim Axelrod. Mathis had dated Charles Bryant in that past summer and had recently broken things off. Jackie had just met him that night, but Caitlin Mathis already knew him well. Police soon uncovered video of a man she was last seen with at some college bars in Denton, Texas. Jackie Vandagriff, a 24-year-old college student, had been found murdered. In September 2016, Grapevine, Texas, police responded to a gruesome discovery in a park.
