Benjamin Crump, an attorney for the family of Clark said: "This independent autopsy affirms that Stephon was not a threat to police and was slain in another senseless police killing under increasingly questionable circumstances".

Protests have rocked Sacramento since Clark's shooting, including delaying National Basketball Association games.

Police waited about five minutes before rendering medical aid.
Over the weekend, Matt Barnes' led the protest rally for Stephon Clark.
Imam Omar Suleiman, who helped prepare Clark's body for his memorial service said police "massacred" the Sacramento man. The Sacramento Police Department initially said Clark had "advanced toward the officers" while holding what they believed to be a firearm.
