Duskwood ending

This ending does not make sense. Richy kidnapped Hannah and held her all this time so she doesn't incriminate him by showing the receipt to the police. Then what was Richy saying here? It wouldn't work out for him if Hannah got out and incriminated him. (See pic)
Why get RID of the suicide letter that Amy wrote? Leaving that behind would at least hint at the possibility of suicide. Now it 100% looks like the mwaf killed her and ofc that receipt would incriminate him. Like I get that his fingerprints would have been on the og, but he could've forged another one while wearing gloves or done literally anything
Why hold Hannah? If he gets rid of that receipt (only incriminating evidence) it's all good. That camera detected motion was all. No one could've proved it was Richy. Not even Jake could do that. Holding Hannah was just unnecessary trouble and caused him to do several illegal stuff in succession like harming Jessy. He could've explained that receipt too in some other way, it's not impossible

I feel we deserved a more clear ending after all the cloud hacking hell we went through
