The pictures from HIE in the People's Exhibits (#28 and #29) show BM carrying two bags (or pillowcases) with items inside and some loose clothing and a pair of boots into the hotel and waiting near the elevator at 8:46AM (the camera's clock showed 7:46 AM, but was an hour off) before emerging from his room at 10:06AM wearing a different shirt and carrying those same two bags, boots and some loose items. And in the AA, Grusing testified that BM had checked in before he carried those items in.
So, BM wasn't waiting to check in as he was parked at Men's Wearhouse as he had already done so.
I find it interesting that all of his documented throwaway locations are in very close proximity to each other. The transit stop (Trash Dump #1 before going to HIE), McDonald's and Men's Wearhouse (Trash Dumps #3 and #4, after spending an hour or so at HIE) are all within 2-3 blocks (probably less than a mile) of each other and the HIE is only about 3 miles away from those. I suppose there could have been more on the trip to Broomfield and LE didn't detect those.
But, if he was dumping at the closed-at-the-time-due-to-Covid Men's Wearhouse, why bother to make that quick stop just about a block away to place things in the trash bin at McDonald's? (That was where he is seen on camera using first one hand and then both to push something down deeper into the bin.). For some reason, he had some small items he wanted to place in that likely heavily used bin at McDonald's, but what?
Also, immediately after the Men's Wearhouse stop, where he spent some time, he made the call to MG - the one about which she described him as sounding like he'd had the worst night of his life. He asked her to ask JP to join them in Broomfield during that call and that was the first either MG or JP was made aware he wanted to add JP. So, did he meet with someone at Men's Wearhouse and as a result of that meeting decide to add JP? Perhaps to implicate JP in some way?
