The letter addressed to Donald Trump Jr. led to Trump's daughter-in-law, Vanessa Trump, being taken to a hospital after opening it in Manhattan on Feb. 12. Two other people also went to the hospital but the white powder in the envelope proved to be harmless. NYPD hazmat units had tested the material and determined it was cornstarch, a police spokesman told Newsday. The charges filed by federal prosecutors against Daniel Frisiello, 24, of Beverly, Massachusetts, included mailing a threat to injure a person and one of false information and hoaxes to at least five addresses around the United States, according to court papers. The first letter, sent to Donald Trump Jr. at an East 54th Street address, contained a letter that read in part, "You are an awful, awful person ... you are getting what you deserve," prosecutors said in court papers. Similar threatening letters were send to U.S. Senator Debbie Stabenow of Michigan, the U.S. Attorney for California, a law professor at Stanford University and a California man running for Congress as a Republican, prosecutors said. In 2016, white powder, which also proved harmless, was sent to the home of Eric Trump, TrumpJr.'s brother. Prosecutors said reviews of social media posts led them to view Frisiello as a potential suspect and that a search of his trash revealed a computer printout referencing two of the people who received the threatening letters.
