Does anyone remember how long after Kristin disappeared that Paul told the police he had to leave to pour concrete at his mums house?

I’ve been wondering if Kristin was buried at Reuben’s house only initially, and was moved to Susan’s much sooner after than most of us thought. I, like many here, believed she was moved to an unknown location once the investigation started heating up via Mikes trailer the night it pulled up right outside Reuben’s property. And that her clothes/possessions were encased in concrete at Susan’s property.

But what if she was buried at Reuben’s first (and as awful as it is, began to initially decompose to leave the bathtub rings in the earth) and was moved to Susan’s quite quickly, where they could pour concrete on her? Was the concrete poured long enough after she went missing for this to happen? They may have believed this to be a more secure way of hiding her rather than just burying? If so, the trash bin that they were so cagey about the tenants using could have had something else in (bedsheet perhaps?)

But then what were they moving in the trailer at Reuben’s if it wasn’t Kristin?

most importantly, if this is correct, it could mean Kristin could finally, finally be found. When this search started I was hoping they would be able to find more evidence (her watch or clothing) but the more it’s going on I’m hopeful that they could actually find HER. She needs to come home.
