Surely, you don’t mean to suggest that stepdad wanted to get rid of this inconvenient reminder of his wife’s past, cruelly forced his vulnerable illegal alien wife to go along, buried the boy alive on purpose in the dead of night, and the witness/savior could see this was happening but was afraid to confront the murderer...
Imam Chewbarkah says bury him in the boy’s grave, fainting optional.
I’m not sure that the other guy was a witness/savior. Maybe he was just a vulture looking to see what he might be able to steal off the body. Or, since it’s Islam, maybe he was going to do something worse to the boy’s ‘corpse’ and then realized the kid was still alive. There’s no bottom to the depravity of some muzzies so I don’t automatically ascribe good motives to their actions. Besides, it’s terribly creepy that he watched and didn’t intervene or at least call out so the step-dad would know that his actions had been seen.
