The man who gunned down New York Police Department Officer Brian Moore, who was in an unmarked vehicle in 2015, has been found guilty of first degree murder.

The jury deliberated for about five hours over two days before convicting career criminal Demetrius Blackwell, 37, Thursday in the death of Moore, 25, of Plainedge. The officer died two days after he was shot twice in the head on May 2, 2015.

The jury also convicted Demetrius guilty of attempted murder for shooting Moore's partner, Officer Erik Jansen, who was unharmed.

The courtroom scene showed a sea of NYPD officers on hand to see Blackwell served justice.

'He's remorseless and just doesn't give a damn,' Queens Assistant District Attorney Dan Saunders said.

The split second confrontation happened on a street in Queens Village after a neighbor of Blackwell's called 911 saying a man threw a brick through the window of his home.

Prosecutors say Moore and his partner were on patrol in an unmarked police car when they responded.

After turning onto 104th Road from 212th St., the pair spotted Blackwell who immediately walked off in the opposite direction.

He appeared to adjust something on his waist, prompting the officers to command him to stop and ask if he was hiding 'something.'

'Yeah, I got something,' Blackwell barked, prosecutors said.

He whipped out his revolver and opened fire, striking Moore twice in the head, prosecutors said.

The young officer, the son of a retired NYPD sergeant, died two days later.

Blackwell was also found guilty of second degree criminal weapons possession.

His attorney, David Bart, had told jurors that his client was paranoid and was not in control of his actions at the time of the shooting.

'Mr. Blackwell has seizures and psychosis mixtures that shows he was not responsible,' attorney Bart argued. 'He acted badly, wrongly and stupidly, but it was not intent to kill.'

Saunders countered, saying there was 'no loss of self-control.'

'Officer Brian Moore was killed because he was a police officer,' Saunders said.

The scene inside court hearkened back to Moore's funeral where over 30,000 officers strong came to pay their respects to Moore.

Blue ribbons were tied to utility poles and trees in this Long Island neighborhood on as thousands of officers said goodbye to the New York City police officer slain on patrol.

Purple bunting hung with photos of Officer Brian Moore in the windows of businesses near the Fredrick J. Chapey and Sons Funeral Home in Bethpage. Heavily armed officers patrolled the streets and officers with sniper rifles were stationed on rooftops of nearby businesses.

Moore had been on the force for only a handful of years, but he had already built up a record of more than 150 arrests and had earned meritorious service medals. He was the son, nephew and cousin of New York Police Department officers. They were at his side when he died at a hospital.

New York Gov. Andrew Cuomo leaves the wake for Officer Moore. 'It's an awful, frightening reminder of the sacrifice so many men and women in law enforcement make,' Cuomo said

Gov. Andrew Cuomo was among the mourners attending the wake.

'It's a terrible tragedy,' Cuomo said afterward. 'It's an awful, frightening reminder of the sacrifice so many men and women in law enforcement make.'

The governor told reporters he admired that Moore had followed in his father's footsteps as a police officer. Cuomo's father, Mario, had served as New York's governor in the 1980s and `90s.

'I said to the father, ''Your son must have really loved you,'' Cuomo told reporters. 'He followed his dad into the business. He wanted to be like dad. He was proud of dad.'

Friends remembered Moore as a good guy eager to join the police force.
