subsection, it shall be an affirmative defense that the defendant committed the proscribed
act or acts under the influence of extreme emotional disturbance for which there was a
reasonable explanation or excuse, the reasonableness of which is to be determined from
the viewpoint of a person in the defendant's situation under the circumstances as the
defendant believed them to be, provided nothing contained in this subsection shall constitute a defense to a prosecution for, or preclude a conviction of, manslaughter in the
first degree or any other crime.
(b) Evidence that the defendant suffered from a mental disease, mental defect or

inference may be drawn in some cases that there was an intent to kill. 95 CA 263. Murder is a specific intent crime and
although court's instruction improperly referred to general intent to engage in proscribed conduct, the erroneous instruction
was not harmful beyond a reasonable doubt and defendant was not deprived of fair trial because court also properly
instructed jury that it had to find defendant intended to cause victim's death. 99 CA 230. A homicide influenced by an
extreme emotional disturbance is not one which is necessarily committed in hot blood stage, but rather one that was brought
about by a significant mental trauma that caused defendant to brood for long period of time and then react violently,
seemingly without provocation. 104 CA 780.
