It’s just a guess, but from what I could piece together, it appears they hustled them out & into the van in the driveway to secure the residence. Then they moved in folding chairs and table and brought the Laundrie’s back in but watched/questioned them while they searched the residence. In Florida right now, it’s in the upper 90s, high humidity and raining most days. IMO, they wanted to keep them close (as opposed to letting them go in the lam like Brian, but weren’t in a position to arrest THEM) So they allowed them back in a tightly controlled condition until the search was completed. MOO
