swindler

A swindler is somebody who cheats others out of money. Charm first, then the invoice that never gets paid.

The deception is the method, which is what separates a swindler from a thief. The verb is swindle, and you swindle somebody out of something. The word is slightly old-fashioned and has a whiff of the confidence trick about it, which is why fraudster is now the commoner term in news reports. It came into English from German in the eighteenth century, from a word meaning to be dizzy.
