"Somehow" seems a incredibly vague basis for accusations.
Search the State of NJ website for Elderly Ombudsmen or something of that nature.
Also the owner should contact their proper department in the bank. They will escalate this to the state or national level depending on the mechanisms involved.
Hopefully, you will invest the time and energy to substitute 'somehow' with something more concrete before you attempt to toss someone under the bus. Has any attempt been made to obtain clarification from the accused? Too often, highly complex transactions such as short sales, are simply too complex for the buyer or seller to explain to a third party. Proceed with care.
Best of success to you,
