SACRAMENTO, Calif. Protests engulfed downtown Sacramento on Friday night after an independent autopsy revealed a young black father shot to death by police on March 18 was hit at least seven times in the back.

The march was organized by the Sacramento Black Lives Matter chapter. Dr. Bennet Omalu had announced the results of Stephon Clark s autopsy that morning: Clark, 22, was shot seven times in the back, including his neck; an eighth bullet hit his leg. He was unarmed.

Each one of these bullets possessed a fatal capacity, Omalu said.

The Sacramento Police Department hasnt received an official autopsy from the Sacramento County Coroners Office and did not comment on Dr. Omalus report.

Protesters gathered at 8 p.m. at Sacramento City Hall on I Street where, less than a week ago, Clarks brother Stevante rushed the dais during a city council meeting in protest of his brothers death.

The march started close to an hour later, with upward of 300 people marching until 1 a.m. through the streets of downtown and Old Town Sacramento, disrupting traffic, flooding local restaurants and facing off with police on freeway entrances.

Clarks funeral was held on Thursday. Hundreds of community members attended , along with the Rev. Al Sharpton.
