Perhaps for my benefit alone, I want to try to break down the parts to the laundry detail.
Barry claimed he hadn't used his tranquing equipment in Colorado, but then (probably when confronted with the recovery of the syringe cap) admitted to shooting two deer (who fell asleep and awakened hornless) from the breezeway (again probably to align his story with something LE told him).
If Suzanne's To Do list is legitimate, it isolates the cap essentially to that load of laundry, that day.
Of course it's possible Suzanne started that load in 2019 or on 5/6, but is it reasonable that Suzanne would leave clothes in the dryer for days or weeks on end? Especially in light of her To Do list. I suspect the list itself is time dependent--maybe a Saturday chore list or a Before the Girls Get Home list.
Also Suzanne had clothes in there. Did SHE combine sheets and clothes? I don't usually do that but I have done it, when I have a small linen load and a smaller clothing load and don't want to wait for two cycles.
Did Barry say he saw Suzanne's bike shorts or just shorts?
I wonder how many she had. If it was bike shorts in the dryer and bike shorts, recovered from her closet, as a scent item, that's two pairs.... I wonder if he rifled through the laundry to remove an actual and full biking ensemble. I suspect, whether he did or not, that he made absolute certain no one had opportunity to inventory her wardrobe, to note what might be missing (unless he removed one full set). The white shorts and string top, what became of them?
Let's back this up. Let's say Suzanne started laundry earlier. And finished. What would she have taken out of the dryer? The sheets. Some of her clothes, apparently. Any of his? Socks? Not his shorts, unless he had multiple identical pairs. (Of note, in all those hotel images, he had multiple wardrobe changes, different shirts-- but he may have changed his pants/shorts too -- he could have owned a dozen pairs of identical khaki shorts, two dozen pairs of identical jeans.)
For the syringe cap to be in the dryer with laundry Suzanne started, I think we have to accept that Barry added the cap. What other vehicle than his shorts? (I wonder if Barry is a natural pocketer.) Doesn't make sense that the cap was placed in the wash with the sheets -- because why would Barry fill a syringe in that room? Not impossible however. Especially if he had been sleeping in the daughter's room. He admitted to sleeping on the guest room couch over snoring but maybe Suzanne booted him from her bedroom on 5/6). For more than snoring.
Suzanne may have been expecting Barry to do Mother's Day with her and the girls, before leaving in the late afternoon, for Denver. (To repair the wall with MG.) Suzanne may have been under the impression he'd be gone Sunday night and two or three additional nights... three or four nights she wouldn't have to sleep next to him, plus any during the girls' camping trip. Still, if he was sleeping in that room, he could have prepared the dart there, in the vicinity of the sheets, then gathered up by Suzanne, syringe cap unnoticed. But.... if he was sleeping in that bed, for Suzanne to change the sheets on Saturday makes no sense. Unless Suzanne had reason to believe that Barry was leaving for Denver on Saturday. Who knows what story to told her.... but if she did the sheets on Saturday and if she did it because Barry had been sleeping there, then she didn't expect him to be home on Saturday night! She may have had a huge willingness to be extra accommodating on Saturday because she believed she had a vacation coming -- vacation from him, that is. 5/9 or 5/10 through 5/12 or 5/13. Time to talk to the girls, without him....
Anyway, we have Barry somehow adding the cap to Suzanne's laundry.... and then Barry telling LE what he eventually saw in the dryer. Curious!! Why? Why did he look in the dryer? He said he was looking for socks. Favorite socks? His only socks? Chipmunk socks? If he says socks, I have to question it.
We know he knew there was laundry because he had to have added his shorts, so what did he remove?????? All his t-shirts? For his wardrobe changes? (But why wash them?)
IMO Barry took something out of the dryer. Because he needed to wear it or he needed to discard it. Not his shorts. Socks like he said (he was looking for)? His shirt? Underwear? A brown towel?
Between 5/9 and 5/10, Barry did a full cycle of laundry, and opened the dryer -- so something was important to him. And everything he didn't take, didn't.
What, what, what could be the significance?
What made him think to do laundry?????
Can any of you make sense of it?
My brain is on a spin cycle.
