On the morning of Friday, May 28, 2021, 37-year-old Ivanildo Barros, a Black / African American man, was shot and killed in Dorchester, Boston. Officers from District B-3 responded around 11:50 a.m. to the area of 590 Park Street after a report of a person shot and found Barros suffering from gunshot wounds; he was pronounced dead at the scene.

Police say the shooting followed an argument earlier that day near 77 Spencer Street involving Barros and the brother of 46-year-old Dorchester resident Nickoyan Wallace. The confrontation continued into the backyard of 590 Park Street, where Barros was shot multiple times, including twice in the head.

The day after the killing, members of the Youth Violence Strike Force arrested Nickoyan Wallace, who was charged with murder and was expected to be arraigned in Dorchester District Court.
