Activists against mass incarceration marched Monday to remember Kalief Browder.
The 22-year-old committed suicide in June of last year, after spending three years on Rikers Island without being convicted of a crime.
He was arrested for allegedly stealing a backpack, something he denied doing.
He spent the next three years on Rikers awaiting trial and more than 1,000 days in solitary confinement.
At a rally in Columbus Circle, marchers said they came not just for Kalief but for the many others they say are being abused by the criminal justice system.
"I'm tired of sticking around, waiting for someone else to suffer," said Akeem Browder, Kelief's Brother.
"I don't think it's just the officers, I think it's the people who put him in jail, but not just him, people that place people in jail without them knowing their bail, people that place people in jail for petty crimes," said one marcher.
"Children have no business in adult facilities," said another. "They're brutalized by guards, they're brutalized by gangs, as we saw with Kalief Browder, and it's time we say enough is enough."
Browder was in the process of filing a lawsuit against the city in the months leading up to his death.
The march also paid tribute to eight people who died in police custody, or because of alleged brutality or recklessness, including Eric Garner.
