As the departmental trial of the police officer who killed Ramarley Graham continues, Graham's family and supporters made it clear what result they're looking for. 

Lawmakers joined Graham's family at a rally in front of police headquarters in Lower Manhattan, where they chanted, "Fire Richard Haste. Fire Richard Haste."

Haste is being tried by the NYPD for shooting and killing the 18-year-old in February 2012. 

Family and supporters say they're not getting enough information from the current proceedings. 

"My son is dead, and five years later, it's a whole pack of lies in that courtroom," said Constance Malcolm, Graham's mother. "Again, two officers that was supposed to be surveillance (at) the bodega that follow Ramarley testified that they never saw Ramarley running."

"When it comes to holding NYPD accountable, and we talk about the truth just doesn't matter, I'm listening to attorneys in there flipping the script and twisting the conversation," said City Councilman Andy King of the Bronx.

Haste was one of several officers who chased Graham into his Bronx home. 

The officers believed Graham had been involved in a drug deal, and Haste said he thought he had a gun. No weapon was found.

Haste takes the stand Friday.
