I do not know. Based on your summary, it is difficult to see how the widow would have been able to legally access the CDs in the first place. If we know how that was done, it would be easier to give you some kind of answer. The probate court can generally fashion a remedy, if something inappropriate was done. You are best off retaining an attorney to assist you with this, particularly if the accounts have significant value.
It also strikes me as possible that the CDs could have been a spousal allowance or exemption through probate. You should have an attorney review the entire probate file and investigate further.
