I'm confused by the OP is talking about his sister in law, and after that about the second shooter and then talking multiple times about "her". It feels to me like he some times is referring to his sister in law by "she" and sometimes by the 2nd shooter.
I would love to have placed a comment on this requesting the OP for clarification. But it appears like there was some drama before that went to make clarifications on this not welcome.
What I'm asking here for is:
What can I do in this kind of situation to get clarification?
