Liu, a seven-year veteran, was married two months ago.
Ramos, who joined the department two years ago, was married with a 13-year-old son.
They were assigned to a special crime-reduction patrol in Bedford Stuyvesant.
Both were pronounced dead at 3:40 p.m. at Woodhull Hospital, the New York City Police Department reported.
Sources told CLIFFVIEW PILOT that 28-year-old Ismaaiyl Abdulah Brinsley shot an ex-girlfriend in Baltimore around 6 a.m. after she tried to warn police, then took a train to New York City, posting several threatening comments (below) along the way, before heading to the corner of Myrtle and Tompkins avenues in Bed Stuy.
After shooting both officers through their front passenger window around 2:45 p.m., he ran to a nearby subway station and shot himself in front of several horrified witnesses as police closed in (photo, above).
“They engaged the guy and he did himself,” one investigator told the New York Post.
Another source told the Post that he was seeking to avenge Eric Garner and Michael Brown.

“Today, two of New York’s finest were shot and killed with no warning, no provocation,” New York Police Commissioner William Bratton said. “They were, quite simply, assassinated — targeted for their uniform.”
A Baltimore County Police spokeswoman told the Baltimore Sun that officers tracking Brinsley’s posts and the location of his cellphone notified the NYPD of the threats in a phone call at 2:10 p.m.
They faxed a warning poster around the same time, the spokesman said. At 2:50 p.m. a Teletype was sent to the NYPD’s real-time crime center.
“The tragedy here is that just as the warning was coming in, the murder was occurring,” Bratton said.
Brinsley had no fewer than nine arrests the past decade, on charges ranging from assault, tresspassing and shoplifting to obstruction and carying a concealed weapon, records show.
One of his Instagram posts included an image of silver automatic handgun with a wooden handle. Another featured camouflage pants and blue sneakers matching those he wore.
“I’m putting wings on a pig today,” he wrote. “They take 1 of ours….. Let’s take 2 of theirs #ShootThePolice #RIPErivGardner [sic] #RIPMikeBrown This may be my final post, I’m putting pigs in a blanket.”
