On July 4, 2021, Jonathan Alvarado Santiago, a 28-year-old Hispanic man, was shot and killed outside a residence on Valencia Drive in Pontiac, Michigan. He and 30-year-old Christopher Cintron-Mateo were both found with multiple gunshot wounds at the scene.

Oakland County Sheriff’s deputies arrested 22-year-old Dazon Louis Mathis, who had been staying at the home, and a firearm recovered at the scene was believed to be the weapon used in the double homicide. Mathis was charged with two counts of first-degree murder and related firearms offenses. His defense raised questions about his memory and family history of psychological issues, prompting a court-ordered psychiatric evaluation to assess competency and criminal responsibility.

What does anyone in the area remember about the Valencia Drive residence or the Fourth of July that year that might be relevant to the case?
