Nearly five years after unarmed teenager Ramarley Graham was shot dead by an officer in his own home, a police department trial has been set against the cop who pulled the trigger. NY1 Criminal Justice Reporter Dean Meminger says the officer is charged with failure to use proper tactics.

Another protest was held Thursday demanding Officer Richard Haste be fired for fatally shooting 18 year old Ramarley Graham in the Bronx.

"It is very hurtful and painful to be going through this, court after court, press conference after press conference," said Graham's sister Leona Virgo.

On Thursday Officer Richard Haste appeared at police headquarters for a hearing about his upcoming departmental trial, which could lead to his dismissal.

In February 2012,  officers said they thought Graham had a gun. As the teen entered his East 229th street home, cops ran up and eventually got into the house through a back door.

On the second floor Haste said he feared for his life. He shot and killed the teenager in the bathroom. No gun was found.

The Bronx District attorney did not obtain an indictment, and the Justice Department decided against federal civil rights charges.

"Sometimes the wheels of justice really do not want to move at all," said Attorney Royce Russell. "I don't know if it is intentional, I don't know if it is by happenstance, but five years later I still look at this vehicle that we call the wheels of justice and all tires are flat."

At Thursday's hearing, police department lawyers told an administrative judge they want Haste to stand trial alone because they aren't ready to present a case against Sergeant Scott Morris and Officer John Mcloughlin.

Union lawyers for Officer Haste say all of the cops involved should be tried together and they say the NYPD is playing games.

"The NYC Police Department's own Firearms Discharge Review Board found that the shooting was within departmental guidelines," Defense attorney Attorney Stuart London said. "Officer Haste will litigate the tactics he used in the Police Department Administrative Trial Room."

Graham family supporters say Haste and other officers must go since there have been no criminal trials.

"We are simply talking about a trial of whether Richard Haste should continue to be employed on our tax dollars," said Brooklyn City Councilman Brad Lander.

"New York is not safe when there are officers like this on the police force," said Yul-san Liem ." When the commissioner and particularly when the mayor allows it."

The departmental trial is scheduled to start on January 17.
