Guy on dating site keeps asking for pictures

This sounds just like the guy my mother is talking to.
He's going by ths name Mark Edeh.
He's asked her for 6,600, then 3,500.
Told her to borrow from family, sell her car, home.
Wants her credit score, bank info.

He uses pictures taken off another person's website.

Says he is stuck on a ship in the Persian Gulf, he's from Germany, has a daughter Pamela in boarding school in the UK.
That he's a widower.
Owns a 5 bedroom home in Chicago and many cars.

His bank account is blocked and he needs my mother to send him money to reactivate it so he can hire a private jet to leave where he is.

When she told him she hasn't any way to get that much money, he has suggested and insisted she buy Amazon cards for him to pay his bank with.

But he also told her to give him her bank info so he can transfer money to her, then she can send it to him.

And she's falling for it and trying to come up with it.
Help if you can possibly give me advice on how to get rid of this person before he takes what little she has.

She can't even afford food or her rent but he doesn't care.
