Also one more thing
Could you explain to me in sentence what each of categories means in your interpretation?
For (weapon) I think is an object to interact or use to kill the victim
The (motive) would be reasoning for killer to kill the victim
But what is (accomplice) a person who willingly or unwilling, intentional or unintentionally helping the killer in one way or another?
And (opportunity)? It sounds to me like a way to kill the victim or something like that but I still need your interpretation and your examples for each categories for extra clarification
