Suspect in federal judge's home ambush railed against her in misogynistic book

The man suspected of ambushing the family of the first Latina federal judge in New Jersey posted thousands of pages of writing to the internet in recent years decrying feminism and ranting against her, according to websites registered in his name and address.

The man, Roy Den Hollander, an anti-feminist activist and lawyer, was pronounced dead of a self-inflicted gunshot wound, officials said Monday. Den Hollander, who law enforcement officials said shot and killed the son of U.S. District Judge Esther Salas in an ambush Sunday at her home in North Brunswick, wrote about his hatred of Salas in a self-published book this year.

Den Hollander pushed his books on several websites, according to domain registration records examined by NBC News that match his known address and phone number. In the recently published memoir Den Hollander left online, he called Salas "a lazy and incompetent Latina judge appointed by Obama." Referring to a 2015 case Salas presided over, Den Hollander said he "wanted to ask the Judge out, but thought she might hold me in contempt."

Authorities say Den Hollander approached Salas' home dressed as a FedEx driver, fatally shot her son, Daniel Anderl, 20, and critically injured her husband, Mark Anderl.

Salas, who presided over a civil case five years ago in which Den Hollander provided representation, was in the basement during the attack and was not injured, NBC New York reported.

Den Hollander's writings are littered with language common among the most extreme anti-feminist communities on the web, some of which he was a member of. He was active in anti-feminist and misogynist groups on Facebook, including groups titled Humanity Vs. Feminism and Men Going Their Own Way, according to an analysis of accounts linked to him.

The memoir is one part of thousands of pages of misogynist writings Den Hollander self-published in books and on websites over the last two decades.

In the 1,700-page screed, self-published this year, he also wrote about his hatred of his mother and other women and raged about female judges, including fantasizing about the rape of another judge who presided over his divorce case.

Den Hollander created a website and wrote another book about a previous marriage, in which he laments "the harm caused [to] his property by a Russian mafia prostitute, procurer, former mistress to a Chechen warlord, money launderer, drug smuggler who was aided by her mob associates." In the book, he threatens to seek retribution against the state for what he considers a "Feminazi infestation of government institutions."

Den Hollander repeatedly claimed without substantiation that his ex-wife was a member of Russian organized crime circles in books and on websites. On one website, he uploaded years of tax documents, marriage documentation and correspondence with the FBI. One set of files, cryptically titled "In Case Something Happens to Me.doc" and "Contact Names.doc," includes contact information for Russian lawyers in case of his death. The files were uploaded in September 2016.

Den Hollander spent considerable time in the 1990s in Russia, where he claimed he ran a detective agency. He gave a speech to the Kremlin in 1993, which he posted on his website.

On the same website, he complained of a "feminist infested American judicial system," "feminarchy" and "Obamite bigots," referring to judges appointed by former President Barack Obama.
