N.Y. PEN Law § 125.22

§ 125.22 Aggravated manslaughter in the first degree.\n A person is guilty of aggravated manslaughter in the first degree\nwhen:\n 1. with intent to cause serious physical injury to a police officer or\npeace officer, where such officer was in the course of performing his or\nher official duties and the defendant knew or reasonably should have\nknown that such victim was a police officer or a peace officer, he or\nshe causes the death of such officer or another police officer or peace\nofficer; or\n 2. with intent to cause the death of a police officer or peace\nofficer, where such officer was in the course of performing his or her\nofficial duties and the defendant knew or reasonably should have known\nthat such victim was a police officer or peace officer, he or she causes\nthe death of such officer or another police officer or peace officer\nunder circumstances which do not constitute murder because he or she\nacts under the influence of extreme emotional disturbance, as defined in\nparagraph (a) of subdivision one of section 125.25. The fact that\nhomicide was committed under the influence of extreme emotional\ndisturbance constitutes a mitigating circumstance reducing murder to\naggravated manslaughter in the first degree or manslaughter in the first\ndegree and need not be proved in any prosecution initiated under this\nsubdivision.\n Aggravated manslaughter in the first degree is a class B felony.\n
