'As a minor, Caleb is unable to own real property in the absence of a legal instrument like a trust or will.'
In which case, Caleb's friend (assuming he is a minor and not an adult 'friend' from the KH) did not own the toy and it still belongs to that child's parents, so Caleb's mother is guilty of destroying someone else's property.
The lawyers would have a field day with these nefarious goings on.
