A confrontation over a scooter in Mattapan turned deadly on July 2, 2020. Twenty-two-year-old Justin Cannady, a Boston resident, was shot and killed after an argument on Columbia Road with 35-year-old Rafael Santos Santiago of Malden, who accused Cannady and another man of stealing a relative’s scooter.

The dispute continued as Santiago pursued the men toward Norfolk Street and Woolson Street, where he allegedly opened fire and Cannady was fatally wounded. Neighbors’ 911 calls brought Boston Police to the scene; officers found Santiago still armed with a revolver, gave verbal commands, and took him into custody after he dropped the weapon.

On July 3, 2020, Santiago was arraigned in Dorchester Division of Boston Municipal Court on charges including murder and unlawful possession of a firearm and ammunition, and a judge ordered him held without bail. Does anyone have information or additional details about Justin Cannady’s life or the events that day?
