The Rev. Al Sharpton plans to deliver the eulogy at the Brooklyn funeral for an unarmed man who was shot and killed by a police officer in a darkened public housing stairwell.

The funeral Friday for Akai (uh-KY') Gurley comes at the end of a tumultuous week for the city following a grand jury's decision not to indict a white police officer in the chokehold death of an unarmed black man.

Gurley was killed last month. Police say he and his girlfriend had opened a door into a stairway, and a rookie officer patrolling the pitch-dark area with his gun drawn fired.

The medical examiner has ruled the death a homicide and Brooklyn District Attorney Kenneth Thompson has called the shooting "deeply troubling," saying the shooting warrants a fair investigation.
