Hoping they can pull some footage from any storage unit Barry rented !There are multiple storage unit facilities in the Buena Vista and Johnson Village areas (on the way to where BM drove to the "job" in the southern part of Denver on May 10 and around the area where he turned his phone back on the morning of May 10). But I'd expect that if the remains were placed in a storage unit, BM likely used some kind of sealed container (like the reportedly missing hunting coolers or perhaps a lidded barrel that could not be traced to him).
ETA: Maybe that large, wide "tree pot" he threw away at the hotel in Broomfield was utilized to hold a barrel in the bed of his truck until he arrived in Buena Vista or Johnson Village to stow the barrel in a storage unit?
I'd consider his girlfriend maybe helped him (Shawna Darke ?) , but I doubt he'd trust anyone else with such a crime & handling evidence of murder.
As far as he could, he wouldn't endanger himself with letting someone assist in Suzanne's disposal.
Because Barry cares about Barry's well-being and no one else's.
Imo.
