Correct but bigger, and most likely not foam due to the sheen. Plastic bags can be used for many things in a situation like that, if he was hiding say in above the ceiling tiles. They could hold cartidges, dampen his noise, hold human waste, if someone gave him food he could contain them in it and dispose of them in others, he could use it as a pillow or blanket himself, dampen a cough or sneeze, vomit in it, hold change of clothes and dispose other. So based on so many bags, I would say we flushed him out, and whoever left the roof unlocked for him, told him he has to go in a rush because they are monitoring this board and we told the FBI to RF scan the roof tiles, so he got on his bike and made a run for it, albeit, a little too late. We caught him, Amen.
