Jordan Neely spent the last few weeks of his life riding the subways of New York, hungry, desperate and alone.
But at his funeral on Friday at Mount Neboh Baptist Church in Harlem, hundreds gathered to mourn him, including friends, family members, prominent Democratic politicians and the Rev.
Al Sharpton, who delivered his eulogy, in a public outpouring of grief for a man who spent his final days in solitude and anonymity.
It has sparked debate between those who believe that the man who killed Mr. Neely, Daniel Penny, responded with violent vigilantism to a person who needed help, and those who believe he was trying to stop a threat.
And it has raised questions about safety on the subway and the care provided to homeless and mentally ill people living in the city.
