Demetrius Blackwell, 37, showed only a cold smirk during the sentencing hearing.

A man in New York who shot an NYPD officer in cold-blooded was sentenced to life in prison without parole on Tuesday for the murder of Officer Brian Moore.
Queens Supreme Judge Gregory Lasak admonished the convicted murderer Demetrius Blackwell for his heartless actions before ordering him to live out the rest of his life behind bars.

“You’re a cold, calculating killer,” Lasak said to Blackwell, who was convicted in November of gunning down Moore in 2015.
“You realize what you did. You killed a man for no reason.”

Blackwell, 37, remained eerily icy throughout Lasak’s admonishment showing nothing more than a smirk on his face.
Before Lasak handed down the sentence, Moore’s mother, Irene Moore, addressed the judge, saying that the bond between a parent and a child was the “closest on Earth.”

Blackwell was also convicted of attempted murder of Moore’s partner, Erik Jansen, and criminal possession of a weapon.
Moore was only 25 years old when Blackwell shot him twice in the head on a street corner in Queens Village on May 2, 2015. Working with an elite anti-crime unit that patrolled streets in plainclothes and in unmarked cars looking streets for suspicious activity. Despite his young age, Moore had already amassed 150 arrests as an NYPD officer and garnered awards for his service.

On the night of the shooting, Moore and his partner, Erik Jansen, while responding to calls of a man throwing cinder blocks through a window were riding in an unmarked sedan in Queens Village when they spotted Blackwell crossing the street and appearing to conceal something.

Moore and Jansen slowly trailed him. When they pulled up to him to question him at 104th Road and 212th Place, Blackwell appeared to adjust something on his waist, prompting the officers to command him to stop.
Blackwell instead swung around and opened fire, striking Moore in the head, prosecutors say. Officers raced him to Jamaica Hospital, where he died two days later.
At the trial, a witness testified that he saw an accused cop killer drop his gun while running from the scene of the May 2015 slaying of NYPD Officer Brian Moore.
Abdul Sadhik described seeing the suspect’s clumsy getaway through homes on 104th Rd. in Queens Village.
“When he jumped the fence, he fell, got up and then walked out onto the sidewalk,” Sadhik testified that “As he [Blackwell], was walking, the gun fell out of his pocket. He picked it up and stuck it back in his pants.”
Even in custody Blackwell continued with his furtive movements.
While in police custody at the 105th precinct stationhouse, Blackwell reached into his sneakers and appeared to pull out a razor, testified retired NYPD detective Sean Ward.
“I immediately jumped up, ran into the room and screamed, ‘He’s got a razor, he’s got a razor!’” said officer Ward who was watching Blackwell on a video monitor in a separate room.
It turned out that Blackwell had no razor, but he was carrying a bag of marijuana and a separate one containing cocaine, Ward said.
If convicted, Blackwell faces life in prison without the possibility of parole.
