Shocking new details have emerged about the police killing of a Black man named Daniel Prude in Rochester, New York, in March. Video released by his family shows Prude died from asphyxiation after officers handcuffed him, put a hood over his head and then pushed his face into the freezing cold ground for two minutes while kneeling on his back. Prude was naked and unarmed. He died seven days later. The police encounter began when Prude’s brother called 911 asking for help because his brother was acting strangely. On Wednesday, three Black Lives Matter activists were arrested during a protest. Prude’s family is calling for the firing of the officers involved and the defunding of the Rochester Police Department.
