Man arrested for allegedly sending letters with 'white powder' to Trump Jr and four others

Federal agents have arrested a 24-year-old Massachusetts man for allegedly sending letters containing white powder and threatening messages to five people, including Donald Trump Jr., last month.

FBI's Joint Terrorism Task Force arrested Daniel Frisiello on Thursday at his Beverly home. He's charged with mailing threats to injure and providing false information and hoaxes, according to documents filed in a U.S. District Court in Massachusetts.

The letter addressed to President Donald Trump's son was postmarked from Boston on Feb. 7.

What happened?

Vanessa Trump, Donald Trump Jr.'s wife, opened one of the letters on Feb. 12 at the couple's Manhattan apartment. She called 911 and reported feeling nauseated. Vanessa Trump and two others who were inside the apartment at the time were taken to a hospital as a precaution.

The suspicious powder turned out to be cornstarch.

“These kinds of hoaxes may not cause physical harm but they scare the heck out of people because most of us recall the Anthrax mailings of the early 2000s, when five people were killed,” U.S. Attorney Andrew E. Lelling said during a news conference Thursday.

What did the letter to Donald Trump Jr. say?

According to court documents, the letter said:

"You are an awful, awful person. I am surprised that your father lets you speak on TV. You make the family idiot, Eric, look smart. This is the reason why people hate you, so you are getting what you deserve. So shut the F@CK UP!”

Who else received letters?

Four other threatening letters, also postmarked from Boston, were received across the country last month, according to the affidavit.

Stanford Law professor Michele Dauber, who's been working to recall California Judge Aaron Persky, received a letter Feb.  14.

Persky came under fire after handing down a six-month sentence to Stanford student Brock Turner for sexual assault.

"Since you are going to disrobe Persky, I am going to treat you like 'Emily Doe.' Let's see what kind of sentencing I get for being a rich white male, " the letter said, according to court documents.

Dauber's letter had a "glitter bomb" inside, along with the white powder, according to the documents.

Interim U.S. Attorney for the Central District of California Nicole Hanna received a letter accusing her of  "murdering" Mark Salling, the "Glee" actor who committed suicide January 30.

“Mark Salling was an indicted defendant in a child pornography case prosecuted by the U.S. Attorney’s Office for the Central District of California. On or around January 30, 2018, news media reported Salling’s death and by February 1, 2018, news media reported that his death had been ruled a suicide,” Michael Connelly, an inspector of the U.S. Postal Inspection Service, wrote in an affidavit.

U.S. Sen. Deborah Stabenow (D-Mich.) received a letter during the sentencing of former USA Olympic gymnastics doctor Larry Nassar, who was convicted of child molestation.

The letter criticized Stabenow for supporting Randall Margraves, the father of three of Nassar's victims, who lunged at Nassar in court.

“If you condone Margraves reaction to his daughter’s testimony on Dr. Nassar, you are no better than he is. You deserve what is coming to you like he is thinking, you’re a c**t version of a vigilante, do us a favor go suck a c**k or better yet,” the letter said, according to the court documents.

Actor Antonio Sabato Jr., a Republican who's running for Congress in California, also received a letter.

“You’re an awful person I am surprised that the olive skin mouth isn’t orange. Since you think [former President Barack] Obama is a practicing Muslim that makes you a filthy kyke. Since kykes like you never change. You and [John] McCain Jr belong together in hell, because that is where you’re going not Christian heaven. You know what your party does with kykes,” the letter said, according to the documents.

What else?

All five letters had the same stamp. Three were mailed in red envelopes and two were in green envelopes.

According to Connelly's affadavit, “three of the addresses on the outside of the envelopes appear to have been typed or printed onto a white piece of paper that was then affixed to the envelope with clear packing-style tape. The remaining two addresses were written directly on the side of the envelopes."

“All five envelopes contained typewritten or computer-written textual messages inside in addition to the unknown powdered substance," Connelly wrote, according to the documents.

Frisiello was expected to appear in federal court on Thursday.
