125.20 – Manslaughter in the first degree

§ 125.20 Manslaughter in the first degree.

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 acts under the influence of extreme
   emotional disturbance, as defined in paragraph (a) of subdivision one of
   section 125.25. 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 subdivision; or
3. He commits upon a female pregnant for more than twenty-four weeks
   an abortional act which causes her death, unless such abortional act is
   justifiable pursuant to subdivision three of section 125.05; or
4. Being eighteen years old or more and with intent to cause physical
   injury to a person less than eleven years old, the defendant recklessly
   engages in conduct which creates a grave risk of serious physical injury
   to such person and thereby causes the death of such person.

   Manslaughter in the first degree is a class B felony.
