At a news conference on Monday Parish Coroner Gerry Cvitanovich said Robinson's death had been classified as a homicide based on the preliminary autopsy results, which revealed neck injuries "consistent with compressional asphyxia". While at a gas station on Thursday, Robinson allegedly saw the detectives, who were in plainclothes, and tried to flee the scene, hitting one of the officer's cars as he left the gas station.
Robinson scrambled out of the vehicle and over backyard fences until detectives caught up with him behind a home on Labarre Place.
When Robinson's family emerged from Lopinto's office Monday morning, his mother walked slowly, wearily, supported by tearful relatives.
The four detectives involved in the suspicious arrest have been reassigned to administrative duties pending the outcome of the investigation. "Somebody's family actually lost a life, and I'm very cognizant of that", Lopinto said.
"For me it means unity, coming together and pretty much just supporting the family", protester Regina Hollins told WWL-News.
A Louisiana coroner says a black suspect who died in a battle with white law enforcement officials final week died of asphyxiation and there was proof of stress on his neck. The Jefferson Parish Sheriff's Office does not use body cameras and the officers involved were undercover detectives. Family attorney Hester Hilliard thanked the coroner's office "for their professionalism and their transparency".
As he was trying to drive away Robinson crashed into two vehicles before abandoning his auto and taking off on foot.

"I think there needs to be some oversight with another agency investigating", she said.
"They were in a struggle", Lopinto said.
He said it was too early to conclude whether a choke hold was used during the struggle, adding that Robinson's history of asthma may have played a role in his death.
The FBI's Civil Rights Task Force, which the sheriff also contacted Saturday, is looking into the matter as well, Lopinto said.
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". They administered life saving techniques to the Robinson, but to no avail. Call me cynical, or call me a student of what happens when police kill people.
Among those attending the news conference was Gaylor Spiller of the Jefferson Parish chapter of the NAACP. "We're not prepared to discuss that at this point", said Cvitanovich. There was a struggle, Lopinto said, before Robinson was handcuffed.
When asked for her reaction to the autopsy results, the 61-year-old grandmother said she was not surprised. 'I just want the truth'.
