I see. Your situation is kind of similar to another member’s so I’m going to direct you to their topic, you can see some of my thoughts and recommendations.
As far as magick goes, my recommendation is the same as I gave Drew. An addition (or alternative) to the spells I’d call on goddesses that are protectors of children and justice. There’s Freyja, Maat, Green Tara and many others. If you know a different goddess that’s fine those are only suggestions. If speed is your concern Tara is blindingly fast.
I knew a woman in your position a while ago, with the police connection and everything. She was relentless - she still reported them to the chief, then she reported it to the neighboring precinct and eventually the FBI. It took a while, but the person eventually met their justice. Don’t let that police connection stop you, is all I’m saying.
Anyway, that’s my handful of cents. I’m sure others here will have different advice. Cheers.
