Sec. 53a-55. Manslaughter in the first degree: Class B felony. (a) A person is
guilty of manslaughter in the first degree when: (1) With intent to cause serious physical
injury to another person, he causes the death of such person or of a third person; or (2)
with intent to cause the death of another person, he causes the death of such person
or of a third person under circumstances which do not constitute murder because he
committed the proscribed act or acts under the influence of extreme emotional disturbance, as provided in subsection (a) of section 53a-54a, except that the fact that homicide
was committed under the influence of extreme emotional disturbance constitutes a mitigating circumstance reducing murder to manslaughter in the first degree and need not
be proved in any prosecution initiated under this subsection; or (3) under circumstances
evincing an extreme indifference to human life, he recklessly engages in conduct which
creates a grave risk of death to another person, and thereby causes the death of another
person.
(b) Manslaughter in the first degree is a class B felony.

warning" and statute is susceptible to "arbitrary enforcement" fails to meet burden of proof because person of ordinary
intelligence would have had fair warning that defendant's actions were proscribed and was properly denied by trial court.

therefrom, evidence was sufficient to support trial court's verdict of manslaughter in the first degree with a firearm. Id.

in the proscribed conduct. 56 CA 742. Subdiv. (3): Action of defendant in entering house, after car chase, obtaining loaded
shotgun, walking 100 feet to edge of driveway and shooting victim showed an extreme indifference to human life. 61 CA

of manslaughter in the second degree when defendant himself ingested fentanyl lollipops, there was no evidence that he
or anyone to whom he had given the lollipops had an adverse reaction to them, risks associated with ingestion of Methadose
and fentanyl not commonly known by laypeople, and defendant immediately called 9-1-1 upon hearing the victim was
unresponsive. 106 CA 467
