You are entirely right, both are scams.
If you read
https://www.scamsurvivors.com/forum/vie ... =6&t=24589 - how the scam works you will see what type of scam each one is. Ask your father to read that topic, it might help him realize what he is dealing with.
The first one is a dying widow / inheritance scam.
The second one seems to be in a more advanced stage, since the fake "Interpol" is involved. Usually that's a recovery scam happening after the victim lost already an important amount of money, with a fake authority figure pretending to be real and offering guarantees that the bogus business in real or that there are money to earn from it.
By the look of it, both frauds happens for quite a while now and your father is already at that stage when he believes everything these scammers say.
It is imperative to contact your local police and report the fraud. Also important is to contact the bank - those money were transferred to various bank accounts the fraudster used.
If your father is not willing to do it in person you can do it - the law enforcement and the bank can assist in explaining to your father that he is a victim of a fraud.
If your father runs a business, he will have a financial consultant or a lawyer assisting him with the business - that person can also explain why this is a fraud and why your father will lose all his money while moving forward and accepting all the demands the scammer made.
You can also ask your father to share the details of the scam with us - my email address is below. We will research the details provided and will share with him the result of our investigation. We cannot act on his behalf - he is the only one who can decide to accept the reality or not.
These are some of the options that can be used in this case. Please let us know which one will work for your father.
