According to authorities, the suspect in the killing of two NYPD officers is a 28-year-old Baltimore gang member named Ismaaiyl Brinsley.

On Saturday, Officers Rafael Ramos and Wenjian Liu were sitting in their patrol car in Bedford Stuyvesant, Brooklyn, when the suspect opened fired on them with little warning. The two officers were rushed to the hospital and eventually pronounced dead.

Brinsley is said to have fled to a nearby subway station and fatally shot himself on the subway platform in front of witnesses. He was pronounced dead at the hospital.

Hours before the shooting, Brinsley hinted on Instagram that he wanted to kill police officers. He posted a photo of a silver handgun with the caption, “I’m Putting Wings On Pigs Today. They Take 1 Of Ours…Let’s Take 2 of Theirs.”

During a press conference Saturday evening, NYPD police commissioner William Bratton confirmed that Brinsley shot his ex-girlfriend in the stomach before driving up to NY to kill police, according to the woman’s mother. They say she is expected to survive.

On his Facebook, he posted the following message Saturday morning.

“I Always Wanted To Be Known For Doing Something Right…But My Past Is Stalking Me and My Present Is Haunting Me.”

Rev. Al Sharpton tweeted out that the suspect’s actions are in no way consistent with the peaceful protests against police brutality in the aftermath of Ferguson and Eric Garner.
