Daniel Prude, a Black man who had run naked through the streets of Rochester, New York died of asphyxiation after a group of police officers put a hood over his head, then pressed his face into the pavement for two minutes, according to video and records released Wednesday by the man's family. Prude was from Chicago and had just arrived in Rochester for a visit with his family. Police responded after Joe Prude called 911 to report that his brother had left his house and was experiencing mental health issues. Daniel Prude died March 30 after he was taken off life support, seven days after the encounter with police in Rochester. His death received no public attention until Wednesday, when his family held a news conference and released police body camera video and written reports they obtained through a public records request. The videos show Prude, who had taken off his clothes, complying when police ask him to get on the ground and put his hands behind his back. Prude is agitated and shouting as officers let him writhe as he sits on the pavement in handcuffs for a few moments as a light snow falls. Then, they put a white “spit hood” over his head, a device intended to protect officers from a detainee's saliva. At the time, New York was in the early days of the coronavirus pandemic. Prude demands they remove it. Then the officer's slam Prude's head into the street. One officer holds his head down against the pavement with both hands, saying “stop spitting” as Prude’s shouts turn to whimpers and grunts. Another officer places a knee on his back. The officers appear to become concerned when they notice water coming out of Prude’s mouth. Spit hoods have been scrutinized as a factor in the deaths of several prisoners in the U.S. and other countries in recent years. A medical examiner concluded that Prude's death was a homicide caused by “complications of asphyxia in the setting of physical restraint.” The report lists excited delirium and acute intoxication by phencyclidine, or PCP, as contributing factors. Protesters gathered Wednesday outside Rochester’s Public Safety Building, which serves as police headquarters. Free the People ROC said several of its organizers were briefly taken into custody after they entered the building while Warren was speaking to the media.
