According to court documents obtained by WJTV, a local CBS affiliate, Williams became angry with Pierce, who was dating his mother, and planned to confront him. WJTV reported that in the period leading up to the fatal altercation, Williams had been going through his mother’s phone and read explicit texts between her and Pierce.

Williams had originally planned on robbing Pierce at his home, and he got his cousin, 22-year-old Corey Hodge, and uncle, 27-year-old Bonny Fields, to help him carry out the act. WAPT, a local ABC affiliate, reported that a witness at the scene on May 16, 2022 saw Williams and Hodge approach Pierce and demand his wallet. The witness told the Jackson Police Department that Pierce told them, “We don’t have anything.” Williams then shot Pierce in the chest twice.
