This is interesting: https://law.justia.com/cases/new-jersey/supreme-court/1994/a-101-93-opn.html
Particularly this: “Therefore, we hold that attempted passion/provocation manslaughter is cognizable under the Code as a lesser-included offense of attempted murder.”
So @LilRanger, it looks like it may be a lesser-included offense, though I don’t know if that terminology means “automatic” or not.
It also looks like the bar is somewhat high for proof. You have to be able to prove that there was sufficient provocation, and that there wasn’t time to cool off. But it does look like MB’s lawyers are trying to prove at least probable cause that she & the other fella goaded him into drawing the gun and firing it in the struggle.
It would definitely result in a reduced sentence, and makes sense that they would do that given that there seems to be little doubt that MB was there and did fire the gun, and she was hit.
