(CNN) The death of a 22-year-old African-American man shortly after a struggle with police last week has been ruled a homicide, authorities in Jefferson Parish, Louisiana said Monday.
Cvitanovich said the findings are consistent with compressional asphyxia, which will likely be cause of death at the end of the process.
The four detectives involved in the incident are white, said Sheriff Joseph P. Lopinto, who declined to release their names at this point.
Gaylor Spiller, president of the West Jefferson Parish NAACP branch, said Robinson's family is also seeking a second independent autopsy.
"I like the fact that Sheriff Lopinto stepped up to plate, and he's doing his part," Spiller said, according CNN affiliate WDSU.
Undercover detectives assigned to the case tracked Robinson down at a local gas station and tried to arrest him, according to Rivarde.
"We are hoping for a thorough investigation, an arrest and prosecution of those that caused his death unjustifiably," she said. »
