Jurors on Thursday convicted Demetrius Blackwell of all charges, including first-degree murder, in the 2015 shooting death of NYPD Officer Brian Moore.

Moore was gunned down in 2015 while on patrol in Queens. The verdict for Blackwell came down just a day after the jury got the case.

The 25-year-old officer and his partner were in street clothes in an unmarked car when they attempted to stop Blackwell, who was suspected of carrying a handgun. Authorities say Blackwell opened fire, striking Moore in the head. He died two days later.

Moore’s partner and others picked out Blackwell from a lineup, and prosecutors said Blackwell’s DNA was found on the two bullets left in the cylinder.

Blackwell’s attorney had argued that his client suffers from extreme emotional disturbance.

“He had a severe case of epilepsy that would cause him to fall into psychosis, and because of that, his brain was severely impaired,” said defense attorney David Bart, “so he would react to a situation differently than your average citizen.”

Moore was posthumously promoted to Detective First-Grade. He’d been on the job for five years. In that time, he made 150 arrests and was awarded two medals for his duty. He followed in his father, uncle and cousin’s footsteps.

Statement from Police Commissioner O’Neill on the conviction in the murder of Detective Brian Moore:

“The murder of Detective Brian Moore reminds us of the extraordinary danger police officers face every day, protecting this City. Brian chose this profession to protect others, to do good, and to serve a cause greater than himself. He was murdered doing his job and in defense of every New Yorker. I thank the investigators and prosecutors who worked this case successfully with personal commitment and resolve. To the public who assisted us along the way: thank you for your help in ensuring that this career criminal is removed from the community and not given the opportunity to cause further harm.”
