Susp cried after cop kill – witness

A MAN accused of shooting and killing a cop on a Queens street in 2015 cried in the back of a squad car minutes after his arrest, according to witness testimony Tuesday.

As his police rushed Officer Brian Moore to a nearby hospital, cops nabbed the accused killer, Demetrius Blackwell, and carted him off to jail.

Along the way, Blackwell, 37, turned from a gun-toting tough guy to a blubbering baby, said one of the arresting officers.

“He was crying in the car in the five-to-eight-minute ride to the 105th Precinct,” NYPD Detective Colin Sparks told jurors deciding Blackwell’s fate at a murder trial in Queens County Court.

Officer Erik Jansen was in the passenger seat of an unmarked Crown Victoria when he and Moore, 25, noticed a man walking across 212th St. in Queens Village.

The man allegedly looked in the officers’ direction and walked in the opposite direction.

“He was adjusting something on his waist on his left side, as he turned and started walking back,” Jansen said.

“I saw him turned toward the car, he took an object out from his left side. We didn't know what he had in his hand. It was very quick. When he fired his first shot, we both ducked down. I heard one, two, a break in between and a possible third shot within seconds.”

Jansen later picked him out of a line up. If convicted, Blackwell (photo) faces life in prison without the possibility of parole.
