So, here's the situation: A bride (Girl A) and a groom (Guy A) are having a wedding, and before the ceremony starts, she knew about the groom's affair with their friend (Girl B). So before the ceremony went underway, she eats an entree which was laced with an allergic ingredient, let's say Girl B can't eat flour, and then Girl & Guy A kiss on the altar. Few minutes later, the Guy A goes off and kisses Girl B, not knowing the fact that Girl A's lips were coated with the deadly ingredient. A moment passes, boom, Girl B suddenly has a reaction and dies. As much as it is a sad case, what would the likely charge be if Girl A was A) caught or B) admitted to the crime? And what would Guy A's charge be if he never knew what actually happened?
