MINNEAPOLIS, MN -- The family of George Floyd says an independent autopsy has found that he died of asphyxiation from sustained pressure on his back and neck.
Floyd, a black man who was in handcuffs at the time, died a week ago after a white Minneapolis officer held his knee on Floyd's neck for several minutes.
The officer ignored bystander shouts to get off him and Floyd's cries that he couldn't breathe.
The family's autopsy differs from the official autopsy as described in a criminal complaint against the officer.
That autopsy said the effects of restraint contributed to Floyd's death, but it ruled out asphyxiation or strangulation.
Meanwhile, the brother of George Floyd appealed for peace Monday in the aftermath of riots and arson fires following the death of his brother in Minneapolis
Terrence Floyd appeared at the intersection in south Minneapolis where his brother, a black man, died after a white police officer pinned his neck with his knee for several minutes a week ago.
Wearing a face mask with the image of his brother's face on it, Terrence Floyd spent several minutes of silence at the flowers and other memorials that have sprung up to his brother.
"I understand you're upset," Terrence Floyd said to the crowd through a bullhorn. But he said civil unrest and destruction is "not going to bring my brother back at all. It may feel good for the moment, like when you drink, but when you are done, you're going to wonder what did you do."
Terrence Floyd said his family is "a peaceful family. My family is God-fearing." And he said, "in every case of police brutality the same thing has been happening. You have protests, you destroy stuff … so they want us to destroy ourselves. Let's do this another way."
He told the crowd to vote and to educate themselves. "Let's switch it up, y'all." He said his brother moved to Minneapolis from Houston and "loved it here. … So I know he would not want you all to be doing this."
At the end of his remarks, Terrence Floyd led the crowd in a chant of "What's his name?" answered by "George Floyd."
