What happens if possessions are missing after a person in bankruptcy dies in intestate in Mo?

It depends on the circumstances. If they were stolen or removed by family members without the estate being in probate, someone needs to be appointed administrator of the estate and either report the items to the police as stolen or formally acknowledge the receipt by the heir at law of such item - if it was the intention of he deceased that that person have the item. State laws differ, so consult an experienced estate attorney.

The administrator also continues the bankruptcy to discharge.
