Massei states that - not knowing yet that the serious crime of murder had taken place - Filomena felt this was a petty robbery, and moved things and checked things. She may have rearranged things. Massei states that the photos are thus not representative of the real crime scene. He understands that Filomena was unaware and overcome with emotion when she altered the scene.
What do you think did she rearrange? Nothing about it in her testimony. She took her computer from the ground, that's about it.
BTW the quote you gave doesn't say what you wrote here. Are you sure you remember correctly?
