Robinson's mother, Kiwanda Robinson, and several dozen family members were in the Harvey office of Jefferson Parish Sheriff Joseph Lopinto as he and Jefferson Parish Coroner Dr. Gerry Cvitanovich made public the results of the autopsy conducted Saturday.
Sheryl Robinson, Keeven's grandmother, said, "We want the young Black men to be able to walk the streets and when the police do frisk them, we want them to be able to stand and let the police do their job". She said the organization was supporting Robinson's family and keeping an eye on the case.
The NAACP called for the detectives involved in Keeven Robinson's death to be arrested and charged with murder.
Again, according to the sheriff's office, the deputies then struggled with Robinson, who was carrying what they suspected to be heroin, before they managed to handcuff him.
Gaylor Spiller, president of the West Jefferson Parish NAACP branch, said Robinson's family is seeking an independent autopsy.
"Today is just as hard as Thursday for this family", Hilliard said.
A Louisiana coroner says a black suspect who died in a struggle with white police officers last week died of asphyxiation and there was evidence of pressure on his neck. The demands include the State Police arresting the four detectives implicated in Robinson's death.

He said Louisiana State Police, the Federal Bureau of Investigation and his office will continue to investigate.
Hilliard said the sheriff and coroner have acted with "professionalism and transparency".
Robinson then crashed into two Jefferson Parish deputy vehicles before getting out of his vehicle and running into some backyards in the neighborhood, hopping fences along the way according to authorities.
"You got somebody in 'cuffs, take them to jail", Mr Jackson said.
Lopinto mentioned it was too early to conclude whether or not a choke maintain was used. It was about a block away from the gas station when detectives caught up with Robinson that the fatal encounter took place.
He said that it is unclear if police used a chokehold, but added that officers are "not forbidden from doing that, but they're not trained... to do that on a normal basis". He added that the FBI's civil rights task force is also looking into the matter.
"We've been discussing body cameras for years", Lopinto said.
'They're grieving, and today, they had to find out that Keeven lost his life at the hands of another, and that's very, very hard for them'. "They're afraid of the police". But I knew out on the scene that the gentleman had asthma, I also knew it was a bad air day. He said it was consistent with someone choking, grabbing or leaning on Robinson's neck.
