Wow....An awful lot of people here jumping on the original poster and defending Joe when the OP clearly states that he is not bashing or making accusations against Joe: "This is not intended to bash, criticize, or make accusations against Joe Salazar or his family. Please keep comments factual and limited to your own firsthand experiences with consignment transactions". In fact, this post is hardly about Joe at all...it is a legal question regarding property left with a person other than the owner for a specific purpose, called "bailment", which is then complicated by the fact that the original person entrusted with the property has passed away.
Clearly, regardless of how complicated the process of determining what belongs to whom may be and the fact that Joe's grieving widow is left with this difficult task, property left in Joe's trust does not belong to Joe, nor to his estate...it must be returned to the original owners in the same condition, unless repaired and paid for as agree to.
Any attempt by the wife, or others, to retain such property can easily be considered tantamount to theft by conversion....certainly immoral.
