Status Updates From De laatste steen

I’m fairly convinced someone in the friend group did it but not sure who I feel like Lottie would be to obvious and same with Elliot but I maybe wrong. Maybe it was the dad but I dunno. I find it a fairly interesting book

I’m quite invested I like the character of Jennie and the dynamic she had with Hannah I’m curious as I reckon one of the friend group is responsible to what happened to her maybe Lottie but that feels to obvious but rather maybe she knows who did it and is trying to cover for them?
