A Colombian-born man posing as a wealthy Saudi prince traveled the globe swindling millions from investors somehow dazzled by his spiel. Gignac, using the alias "Sultan Bin Khalid Al-Saud," pretended he wanted to invest hundreds of millions of dollars in the landmark Fontainebleau resort hotel on Miami Beach Billionaire developer Jeffrey Soffer wised up, had his security team check out Gignac and reported his suspicions that he might be an impostor to the feds. The 47-year-old Gignac, locked up in a Miami detention center since November 2017, is now awaiting sentencing next month after pleading guilty to impersonating a foreign government official, identity theft and fraud. Soffer is among Gignac's 26 victims worldwide from whom he stole a total of $8 million between 2015 and 2017. Soffer only lost the $50,000 that he spent on gifts for Gignac before he figured out he was probably a con artist. Gignac, who was adopted by a Michigan family as a boy, grew up to become an international swindler. Despite prior brushes with the law, he lived large in South Florida. Gignac and his partner created a fraudulent investment company, Marden Williams International, in 2015 for purportedly legitimate business opportunities around the world. Gignac and his band of co-conspirators represented that he was a member of the Saudi Royal family and had exclusive business deals. One investment victim from Switzerland sank $5 million into a deal. His business partner, Carl Marden Williamson, introduced Gignac to Soffer and other executives at Turnberry as "Saudi Crown Prince Khalid bin Al-Saud." With his suspicions confirmed, Soffer tipped off the feds, setting off an investigation. Federal investigators reviewed Fisher Island's video footage of Gignac's diplomatic license plates on his Ferrari California and confirmed they were fake. Gignac got busted in November when he flew from London to New York on a passport with another person's name. His arrest sent investigators with a search warrant to Gignac's Fisher Island residence. Investigators also discovered fraudulent diplomatic license plates, a phony diplomatic security badge, unauthorized credit cards, thousands of dollars in cash, and financial documents in the name of a member of the Saudi Royal family. The initial charges filed against Gignac's partner, Williamson, were dismissed in March because he died earlier this year.
