A rally was held by a Bronx police precinct Thursday night, as advocates demanded that the police officer who killed unarmed 18-year-old Ramarley Graham last month should be arrested and face criminal charges.

Ramarley Graham, 18, was shot last month by Police Officer Richard Haste, who along with several narcotics agents chased the teen into his house on East 229th Street in Wakefield after an alleged drug deal.

Police say Haste shot Graham in the bathroom as the teen tried to flush marijuana down the toilet, mistakenly thinking that the young man had a weapon.

On Thursday, Graham's family and their supporters made the second of 18 weekly marches, in honor of Graham's 18 years of life, from their East 229th Street home to the 47th police precinct in Williamsbridge.

The marchers chanted "We are Ramarley Graham" and said they will keep demonstrating until the officers involved in the shooting are arrested.

"We will get justice, because I'm not going to stop, a mother never lays down. I'm going to stand up for my son," said Constance Russell, Graham's mother. "He's not here, but he's counting on me to stand up and I will."

"Who told you there was a struggle in the house? Why are you not trying to find out who is the source of that information?" said Jeffrey Emdin, one of the Graham family's lawyers.

Graham's family previously met with Police Commissioner Ray Kelly, who said he could not do anything before the Bronx district attorney completes a criminal investigation.

The officers involved in the shooting have been placed on modified duty while the investigation continues.
