Lawmakers and the family of an unarmed black teen shot to death in front his grandmother and younger brother by a white police officer are calling on the mayor and commissioner to fire him.

Federal prosecutors declined this week to file civil rights charges against Officer Richard Haste in the 2012 death of Ramarley Graham. It was the last opportunity for Haste face criminal charges.

Haste was initially indicted in the Bronx, but the case was thrown out. A second grand jury declined to indict him.

Haste followed Graham into his home and into the bathroom and killed him. He said he believed the 18-year-old had a gun.

Haste remains stripped of his gun and badge. He has been charged internally and is facing disciplinary proceedings.
