If a Power of Attorney is valid?

If a Power of Attorney is valid? One of the witnesses that signed the POA stated there was no notary present at the time the principal signed this document. But it was somehow notarized later.
This POA was used to obtain $300K plus. Is this POA valid? If no notary was present?
The principal of the POA was an elderly person, age 66, in hospital, disabled from stroke in brainstem.
Wouldnt these actions taken with the use of the POA, fall under Finanical Exploitation of the Elderly, White collar crimes such as Bank Fraud, Embezzelement, Forgery and Larceny?
I hope you can help me. I feel like there are laws broken, but no one will tell me where to go to for help. Or how do I report this?

My two sons are doing what they can to help her. Their ages are 24 and 20. the 20 year old recently relocated to Florida so that he can assist in his mother’s care.

Can ther be joint ”Power of Attorney” between the two boys or is ther a mimimum age requirement?

Keeping Tabs on Executor
What rights do the beneficiaries have to information regarding the execution of a will as the process is going on? And how can we find out (such as appraised value of house, life insurance policies, etc.), other than asking Executor, who refuses to tell us anything? We basically know what the Will says, which is that the assets (house) are to be divided equally amongst 3 children and girlfriend of the deceased. The girlfriend is the executor and we (the children) are concerned about ensuring she acts appropriately as there is already potential evidence of her abuse of her authority (she also had Power of Attorney prior to Dad’s death), amongst other things. We believe she may have liquidated his accounts already (prior to his death) for her own benefit alone, which can also affect payment of his outstanding bills that those funds were supposed to be for (his words).
