Keeven Robinson, a black man who died during an his arrest by Jefferson Parish Sheriff’s Office deputies last week, was “asphyxiated,” officials announced Monday. An autopsy of 22-year-old Robinson’s body showed signs that he had “injuries to the neck consistent with compressive asphyxia,” or when “a person’s neck is squeezed from the outside,” according to The Advocate. His death was ruled a homicide by Jefferson Parish Coroner Dr. Gerry Cvitanovich. The four deputies involved in Robinson’s arrest were following him as part of a “drug-dealing investigation,” and have since been put on “desk duty” after Robinson’s death. All four of the deputies involved were white and did not wear body cameras during the incident. Jefferson Parish Sheriff's Office, Louisiana State Police, and the FBI's Civil Rights Task Force will reportedly participate in the homicide investigation.
