Authorities Link 'Anti-Feminist' Who Killed New Jersey Judge’s Son To Murder Of Men's Rights Activist

Investigators have linked the “primary suspect” in the brazen shooting at a New Jersey judge’s home Sunday evening to another similar killing in California earlier this month.

Roy Den Hollander, 72, has been identified as the person who carried out the attack at the North Brunswick home of Judge Esther Salas Sunday. Authorities say Den Hollander dressed in a FedEx uniform and fatally shot the judge’s 20-year-old son. Daniel Anderl, after he opened the door, according to a statement from the FBI.

Salas’ husband, Mark Anderl, 63, was also wounded in the attack and is recovering at a local hospital.

Den Hollander — a men’s rights attorney who allegedly had terminal cancer — was found dead less than 24 hours after the attack on Salas' home. Den Hollander had apparently died by suicide.

Now, authorities believe that Den Hollander may be linked to another brutal killing on the other side of the country from a week earlier. The earlier slaying has eerie similarities to the attack on the judge’s family, according to the Associated Press.

Marc Angelucci, another men’s rights attorney, was shot to death at his home in Crestline, California on Saturday, July 11.

The San Bernardino County Sheriff’s Department said in a statement they received a report of a possible shooting at 4:03 p.m. on July 11 and arrived at the attorney’s home to find him “unresponsive and suffering from apparent gunshot wounds." Angelucci was pronounced dead at the scene.

A law enforcement official told the Associated Press that, much like the attack at Salas’ home, the suspect in Angelucci’s killing also posed as a delivery driver.

Authorities have also matched the gun used in Angelucci’s killing to the one used in New Jersey, according to ABC News,

Paul Elam, a friend of Angelucci’s and a fellow men’s rights activist, said that Den Hollander had harbored a grudge against Angelucci for years, according to CNN.

Den Hollander had filed a lawsuit in 2015 — which was being overseen by Salas — that argued that the selective service registration was discriminatory because it only applied to men.

Angelucci later filed a similar lawsuit in conjunction with the National Coalition for Men — enraging Den Hollander, who allegedly saw the fellow attorney as a rival.

"Roy was furious and beyond words furious, absolutely enraged that (the National Coalition for Men) and Marc Angelucci were getting into the selective service case. He viewed that as something proprietary for him," Elam said on a Facebook Live, according to the news outlet. "He saw Marc's work in that respect as an intrusion into his space. He was more than angry about it, he was livid."

Harry Crouch, president of the National Coalition for Men, told CNN that Den Hollander had been kicked out of the organization in 2015 after he called and threatened Crouch after being left out of the lawsuit.

“He was very upset and threatened to come to California and kick my ass,” he said.

Den Hollander, a self-proclaimed “anti-feminist” attorney, spent his time filing lawsuits against programs he believed favored women — including challenging the constitutionality of ladies’ nights at bars and suing Columbia University for offering women’s studies classes.

Investigators are now trying to determine whether the 72-year-old’s terminal cancer diagnosis prompted him to go after his supposed enemies — something he himself appeared to suggest in angry rantings he posted online.

“Death’s hand is on my left shoulder … nothing in this life matters anymore,” Den Hollander wrote, according to The New York Post. “The only problem with life lived too long under Feminazi rule is that man ends up with so many enemies he can’t even the score with all of them.”

After Den Hollander's body was discovered, investigators found a photo of New York Chief Judge Janet DiFiore and the address of a state appeals courthouse in his car, a state court spokesperson told the Associated Press.

While Angelucci and Den Hollander both advocated for men’s rights, Angelucci’s friend Cassie Jaye told CNN that her friend Angelucci had approached the movement differently and was not anti-women.

“When litigating on behalf of men’s issues, he was still always considering the female plight and perspective,” she said of Angelucci. “He was just a great guy and well-loved within the men’s rights community.”
