The only thing I can add to this question, which also haunts me, is IIRC, LE deemed the recovery scene a Hazmat situation, for reasons we do not know. I think I opined a while back that perhaps they saw signs of vomit from one or more of the family members. But something visible likely triggered a Hazmat reaction. And to prepare for that takes time, including special equipment, clothing, and perhaps personnel. That may not have contributed to the delay in recovering the bodies, but it comes to mind.
