NEW YORK, Ny. - It was a heartbreaking day for New York City and the entire country.
According to authorities, two NYPD officers, now identified as Wenjin Liu and Rafael Ramos, were killed by a gunman while sitting in a patrol car in Brooklyn.
"They were shot with no warning, no provocation, they were simply assassinated," said NYPD Commissioner Bill Bratton.
The shooter, 28-year-old Ismaaiyl Brinsley, killed himself shortly after the attack, according to police.
Authorities say Brinsley shot his former girlfriend in Maryland earlier in the day and then headed to the Brooklyn area to carry out his second deadly attack.
Sources say Brinsley had posted anti-police comments online saying he was going to "shoot two pigs" in retaliation for the death of Eric Garner.
Garner was killed after being put in a choke-hold by an NYPD officer in Staten Island this past July. The officer involved in this case were not indicted.
The murders of the two officers in Brooklyn hits close to home for many in Pennsylvania.
It was just three months ago police say Eric Frein shot and killed Corprol Bryan Dickson and injured Trooper Alex Douglass after an ambush at the Blooming Grove Barracks in Pike County.
