The death of a Black man who died in police custody has been ruled a homicide by asphyxiation, according to HuffPost.

Keeven Robinson, 22, died Thursday at a Jefferson Parish hospital. He had been in a car chase with law enforcement officers, who said he was a suspect in a drug investigation.

During the chase, Robinson exited his vehicle and ran but was caught by four White police officers. Following a struggle, he was taken into custody, where he later died, HuffPost reports.

“This initial medical classification does not take into account whether the homicide was an intentional act, accidental act, or an act incidental to a law enforcement action,” Jefferson Parish Sheriff Joseph Lopinto said in a statement.

Following the coroner’s report, 100 people marched in the streets calling for justice.

“I like the fact that Sheriff Lopinto stepped up to plate, and he’s doing his part,” Gaylor Spiller, president of the NAACP’s West Jefferson Parish chapter, said, according to WDSU. “He knows that the NAACP will be on his trail.”

The four unidentified officers involved have been reassigned, per reports.

“Somebody’s family actually lost a life, and I’m very cognizant of that,” Lopinto said during a news conference. “That doesn’t mean our officers did anything wrong, or it may mean that they did something wrong.”
