David Green, 68, a retired Massachusetts State Police trooper of 36 years, was killed in Winthrop, Massachusetts, on June 26, 2021. The attacker allegedly walked past several white people and opened fire on two Black residents, shooting Green in the head and torso and also wounding 60-year-old Ramona Cooper.

The shooter, identified as 28-year-old Nathan Allen, was shot and killed by a Winthrop police sergeant after he refused to drop his weapon and pointed it at the officer. Investigators later recovered handwritten journals attributed to Allen containing white supremacist and anti-Semitic rhetoric. The Suffolk County District Attorney’s Office investigated the deaths as a hate crime, concluding Allen specifically targeted Green and Cooper because they were Black. Friends and family remembered Green as a kind, helpful man and a hero who may have been trying to intervene.
