Sacramento police shot Stephon Clark seven times from behind, according to autopsy results released Friday by a pathologist hired by Clark's family, a finding that calls into question the department's assertion the 22-year-old black man was facing officers and moving toward them when he was killed.
Dr. Bennet Omalu, whose study of a degenerative brain condition in football players prompted the NFL to adopt new safety rules designed to prevent concussions, also determined Clark took three to 10 minutes to die. Police waited about five minutes before rendering medical aid.
"The proposition that has been presented that he was assailing the officers, meaning he was facing the officers, is inconsistent with the prevailing forensic evidence," Omalu said at a news conference with family attorney Benjamin Crump.
He said it was not clear if Clark would have survived had he gotten immediate medical attention.
Sacramento police responded with a brief statement that said the department had not yet received an official autopsy report from the Sacramento County coroner's office. It said the coroner's death investigation is independent from the investigation being conducted by police and the state Department of Justice.
A day after the March 18 shooting, police distributed a press release that said the officers who shot Clark "saw the suspect facing them, advance forward with his arms extended, and holding an object in his hands."
Police video of the shooting doesn't clearly capture all that happened after Clark ran into his grandmother's backyard. He initially moved toward the officers, who are peeking out from behind a corner of the house, but it's not clear he's facing them or that he knows they are there when they open fire after shouting "gun, gun, gun."
After 20 shots, officers call to him, apparently believing he might still be alive and armed. They eventually approach and find no gun, just a cellphone.
The shooting has produced almost daily angry but peaceful protests in the downtown area of California's capital city. The autopsy heightened calls for justice and skepticism toward police among community activists.
"Generally speaking, part of the outrage in the community is not only for this shooting but it's for all police shootings that are happening of unarmed people," said Dale Galipo, another Clark family lawyer. One of the big questions we all have to ask is: 'What do we need to do for these shooting to stop?'"
Black Lives Matter Sacramento planned a protest Friday night outside City Hall and other actions were possible.
"You'll probably see a little bit of everything," said Berry Accius, a community activist. "But that's not for me to say, it's for the people to decide."
Police were called to the South Sacramento neighborhood on March 18 after a neighbor reported someone was breaking car windows. A police helicopter identified a suspect, who ran as police on the ground gave chase.
The helicopter video shows the two officers at the corner of Clark's grandmother's house and Clark on the backyard patio. He moves toward the officers' position as they peer around the corner and open fire.
Clark staggers sideways and falls on his stomach as officers continue shooting.
Omalu said any of the six bullets that hit Clark in the back and one in the neck could have been the fatal shot. An eighth bullet went into Clark's thigh.
The autopsy was released a day after an emotional funeral service. The Rev. Al Sharpton delivered the eulogy and praised demonstrators for their restraint and urged them to follow the lead of the Rev. Martin Luther King Jr. and his advocacy of nonviolent protest.
Later in the day, police in riot gear stood waiting outside the Golden 1 Center as fans wove through barricades and fencing to enter a Sacramento Kings-Indiana Pacers game. Twice since the shooting, demonstrators had blocked thousands of fans from entering the area.
But protesters never came to the arena Thursday night, heeding calls from Clark's brother, Stevante Clark, and Black Lives Matter organizers to avoid the arena.
Instead, they blocked rush hour traffic on nearby downtown streets.
The Kings and their owner have supported the family.
Players Vince Carter, Garrett Temple and Doug Christie, a retired player, plan to appear Friday night at a youth forum staged as part of a new partnership with the Build Black Coalition and Black Lives Matter Sacramento to increase education and workforce training for black youth. Former Kings player Matt Barnes attended the funeral and helped pay for it.
