On July 4, 2021, 17-year-old Mi’quarius Alexander was killed in a mass shooting during an unofficial community block party in the Hamilton Park neighborhood of Dallas, Texas. The gathering reportedly had hundreds of attendees; witnesses described chaotic gunfire and residents running for cover. Three people died that night — Mi’quarius Alexander, Alvin Ray Murray III, 22, and Hassan Blazer, 19 — and three others were injured.

Dallas Police investigators recovered surveillance footage from nearby cameras that captured suspects moments before the shooting and showed some of the gunfire at a distance. Four people were arrested and later indicted on capital murder charges: Kejuan Lewis, 17, Taqualon Jones, 19, Bryce Jones, 19, and Akil Anderson, 19. Police have not announced a clear motive for the attack.

If anyone attended the Hamilton Park block party or has information about the shooting or the victims, please share what was seen or heard that evening.
