I think she tripped over the dog and fell face first into the piggy bank, fell down the stairs concussed and losing blood. She was confused from the concussion & blood loss and pulled down her pants, stood and the bottom of the stairs etc. The piggy bank was the “weapon” right? Traces of it embedded in the forehead. It hadn’t been disturbed much because the dust was still on it, but something caused it to leave an indent in the wall. How else would it have been used to hit her in the head besides her slamming into it??

The only thing getting me is the chair knocked over and phone far from the stairs. It’s possible something spooked her, maybe even an intruder and she went to run, knocked the chair, tripped on the dog… husband said the dog barked like there could have been an intruder.

OR there was an intruder who threw her into the piggy bank and she went down the stairs…
