Family and supporters on Friday marked the one-year anniversary of the death of Eric Garner with rallies and vigils demanding police reforms and justice in the controversial case.

Protesters headed to Staten Island, the New York City borough where Garner, a 43-year-old black father of six, died last July 17 after New York police put him in an apparent chokehold.

His death spurred nationwide debate over how U.S. police treat minorities. Video footage of police arresting Garner, in which he could be heard repeatedly saying he couldn't breathe, went viral on the Internet, helping draw attention to the case.

A grand jury declined to indict a white police officer in the incident.

Marking Garner's death, several hundred people planned to rally in Manhattan's Columbus Circle on Friday afternoon, and evening vigils were scheduled at churches in Brooklyn and Harlem.

Garner's 1-year-old daughter and her mother released a white dove in his memory at the spot where he died, local media reported.

On Saturday, the New York Civil Liberties Union and other groups planned a rally in Brooklyn to demand justice for Garner, while activist Rev. Al Sharpton's National Action Network planned a midday gathering at Brooklyn's federal courthouse.

The Garner family, its supporters and activists want the U.S. Attorney to pursue a federal civil rights case.

Garner's death was ruled a homicide by the city medical examiner, who said police killed him by compressing his neck and chest as they restrained him for selling loose cigarettes.

The family reached a $5.9 million settlement with New York City this week.

"One year ago exact to this day the world shared my pain. No amount of money could bring my father back, no amount of time can fill this void," Garner's daughter Erica wrote on Twitter.

The issue of police treatment of minorities intensified in the month following Garner's death, when a white police officer in Ferguson, Missouri, shot and killed Michael Brown, an unarmed black teenager.

Brown's death sparked violent protests in the St. Louis suburb.
