Here's a comparison:
First person: I peer into my husband’s musty study. The neatness tells me that no one has been there. I smile. They haven't found the incriminating document.
Second person: You peer into your murdered husband’s musty study. The neatness tells you that no one has been there since his death. You smile. They haven't found the document.
The experts insist that the second sounds more ominous. By injecting murdered and death, they say it sounds more natural.
They may be correct, but it doesn't feel right to me.
You need to be comfortable in whatever POV you choose.
