Banks are not allowed to accept lesser ID on a CTR from the elderly or disabled on a case by case basis. To do it, the issue must have been addressed in bank policy in advance.
FIN 1992-R001 You simply cannot "fix" this in arrears, but you need to send your senior executive back to get some kind of identification. As he endorsed the items, I would list him on the CTR as a person on whose behalf the transaction was conducted along with her. He's not a mobile branch; he did this as an individual, not a bank employee.
He made some bad decisions here...
