The following link contains pics of the kitchen. These pics have caused me to go hmm? more than a few times. Studying them is not easy on my phone so let me know what you see. Am I reading too much into the kitchen?

The roll of paper towels on the floor in a kitchen where there isn't much out of place. They aren't the type of thing you leave on the floor with a small child. There is something on the floor in the blood. Anyone know what it is? My best guess is she was putting a the new roll on when whatever happened happened. Maybe they were knocked off in a struggle or she dropped them and just hadn't picked them up yet. Probably means nothing.
The trash can. Not a trash can. It's a pail. I can imagine no housewife using a pail as a trash can. The little square under the cupboard trashcans, yes, but not a pail. With kids she'd be emptying constantly. The items in/on the pail look placed there.
The kitchen pics scream to me that the pail holds the answers. Is there an inventory of the pail?
