Gregory Dwight Horton III, a 17-year-old African American, was killed in a shooting in Old East Dallas on June 30, 2019. He was one of two teenagers who died that night; two other teens were wounded and taken to hospital with gunshot injuries. The incident prompted a Dallas Police Department investigation that faced challenges from limited forensic leads and low community cooperation, and authorities reported identifying several suspects amid conflicting witness accounts.

The case generated continued litigation and public attention as families sought accountability and the community organized vigils and advocacy around youth violence and gun control.

If anyone knew Gregory, Zacchaeus Banks, or has information about the June 30, 2019 shooting in Old East Dallas, please come forward.
