On July 4, 2021, a dispute outside a home on Valencia Drive in Pontiac, Michigan, ended in gunfire that killed 30-year-old Christopher Cintron-Mateo and 29-year-old Jonathan Alvarado-Santiago. Deputies from the Oakland County Sheriff’s Office found both men lying in the street with multiple gunshot wounds and recovered the firearm believed to have been used in the killings.

Investigators arrested 21-year-old Dazon Louis Mathis, who was reportedly staying at the residence where the shooting occurred, and charged him in connection with the double homicide. During pretrial proceedings his defense sought a psychiatric evaluation for Mathis, citing memory problems and a family history of psychological concerns; the evaluation was completed and the case moved forward.

Does anyone have information about Christopher’s movements that day or witnessed the disturbance on Valencia Drive?
