MANHATTAN - The family of slain Bronx teen Ramarley Graham continued their call for justice during a rally in lower Manhattan. 

The case has been in the hands of the U.S. Department of Justice since last year, and the teenager's loved ones say the review process is taking too long. 

Graham was shot and killed inside his Wakefield home by NYPD Officer Richard Haste back in Feb. 2012. Two indictments against Haste were thrown out last year, so Graham's parents say the Justice Department is their last hope. 

Graham would have turned 21 years old this past weekend. His mother, Constance Malcolm, says she visited his grave on his birthday and spent time with family.

News 12 reached out to the Department of Justice. Workers there say they are still reviewing the case.
