According to the indictment, McTigue, Blackwell and Melton have been running their scheme since February 2011. Blackwell is a real estate broker and McTigue presents herself as a financial strategist and real estate investor, according to her website. It's unclear what Melton, who is reportedly from Iowa, does. Officials say they purchased and sold properties in Honolulu and Waikiki, along with Waikoloa and Kailua-Kona on Hawai'i Island.
