Demonstrators are set to march through the city today in honor of a Bronx teen who was shot to death by police in 2012.

The activist group Justice League NYC is organizing the march for Ramarley Graham.

The 17-mile march is set to run from his home in the Bronx to One Police Plaza, where a vigil will be held this afternoon.

Graham was 18 years old when he was shot inside his home by Officer Richard Haste, who said he thought the teen was reaching for something in his waistband.

No weapon was ever found.

Criminal charges against Haste were later dismissed on a technicality, and federal prosecutors did not pursue civil rights charges.

Graham's parents and their supporters are calling on the NYPD to fire Haste, who is on modified duty.
