The killer posted about his plans on IG just before too:
Such a ****ed up individual. Treating human life as a pawn for revenge and setting examples. Those two innocent cops were working to feed their families like everyone else has to. There is no excuse for this behavior, at all.
Real tea it was only a matter of time before this happened and now the nypd is about to get super extra. Everybody better stay the **** inside because it's gonna get stupid in the boroughs for a bit.
