An Italian woman who fled a jail sentence for swiping her dying mother’s $15 million fortune is now holed up in a Trump Tower condo surrounded by heaps of stolen diamonds, antiques and artwork, according to legal papers in a nasty, trans-Atlantic estate battle.

High-rolling fugitive Susetta Mion carted a ton of her mother Renata Forti’s luxury goods across the ocean in August 2007 after she had been sentenced by an Italian judge for thievery, according to filings in Manhattan Surrogate’s Court.

Now Mion’s niece, Boston-based immigration attorney Micol Mion Gordon, 34, is fighting her in US and Italian courts, alleging “surreptitious and unlawful looting” of the estate.

“She ruthlessly misappropriated for her own use and enjoyment her mother’s substantial assets, thereby leaving Renata Forti — a formerly wealthy woman — destitute in her final days,” the legal papers claim.
