Clothing as Possible Clue to Date of Death.
A lot of discussion about when BA may have passed.
I think one way to perhaps pin point how long she was alive after the evening of the 11th could be determined by her clothing.
There was video of her at the various places she stopped on the 11th before going home. It should be easy to determine what outfit she was wearing at that time from those video's.
- Was she still wearing the same cloths as in the video when she was found or did she change her clothing?
- If she changed, where in the house is the clothing she was wearing when she was out and about on the 11th?
- If they are in a dirty cloths hamper, how many sets of cloths are on top of the set of cloths she was seen wearing on the 11th?
- Did she do any laundry? (If she was feeling sick I doubt it)
- Were the cloths she was seen wearing on the 11th perhaps in the washer, dryer, folded up or put away already in a drawer or closet?
This would maybe give some idea of how many times BA changed her cloths and maybe how many days BA may have been alive after arriving home on the evening of the 11th.

@Joe Friday Excellent thinking.

Could further pinpoint time of death.
Just speaking generally, is it possible that after the errands outing that a person in her condition may have been totally overwhelmed? Fatigued, achy, fever, & other symptoms.
Maybe more or less on a sofa or recliner for a day, a couple days?
Only able to navigate to kitchen to grab a snack & water? Bathroom breaks?
Maybe furnishing Mr. H. similar food, for a day or so? DItto w bathroom breaks.
If so, for multiple days, she may have been in SAME CLOTHING as on Feb 11 errand day.
Alternatively she may have had DUPLICATE outfits, say 3-4-5 sets of gray sweatpants & sweatshirts. After all, she & Mr. H were not prepping to be on the red carpet at a gala.
BTW, don't ask me how I know someone w outfits like this, who wears them around the house, almost like a seasonal uniform

lol.
Well, there's likely more merit to the ^ check-the-laundry-basket-and-more idea than these other possibilities. Glad to read alternatives to some "out-there" thoughts I've had.
Thx for your post.
