Just wacko? Suspect in Death of N.J. Judge’s Son Is Linked to California Killing

Roy Den Hollander, the “anti-feminist” who is the prime suspect in the New Jersey shooting, may also have killed a rival men’s rights lawyer, officials say.

The two killings on opposite sides of the country were strikingly similar. A gunman showed up at the front door, posing as a delivery man, and opened fire.

One of the victims was Marc Angelucci, 52, a men's rights lawyer who was killed on July 11 outside his home in San Bernardino County, Calif. Eight days later, a shooter approached the New Jersey home of Esther Salas, a federal judge, killing the judge’s son and leaving her husband seriously injured.

On Wednesday, the F.B.I. office in Newark said in a statement that agents had uncovered evidence linking Mr. Angelucci’s killing to Roy Den Hollander, who is also the primary suspect in the New Jersey shooting.

It was the first time that the authorities had publicly connected the two killings.

Mr. Den Hollander, 72, was found dead in the Catskills in New York on Monday in an apparent suicide, hours after the shooting at Judge Salas’s home. He was a self-described anti-feminist lawyer who wrote thousands of pages in online screeds denouncing women, including female judges.

On Wednesday, the F.B.I. did not publicly say what evidence had been uncovered. But the authorities investigating Mr. Den Hollander’s apparent suicide found a semiautomatic Walther pistol that was of the same caliber as the weapon used in both the California shooting and the New Jersey shooting, according to a law enforcement official briefed on the matter.

Investigators were conducting ballistics tests to determine whether that weapon was used in both attacks, according to law enforcement officials.

The authorities are investigating whether Mr. Den Hollander was seeking revenge against his enemies after receiving a terminal cancer diagnosis, according to a different law enforcement official. In a self-published book last year, Mr. Den Hollander said he learned in late 2018 he had a rare form of melanoma.

Although Mr. Den Hollander detailed extensive grievances against judges and others in his online writings, it was not clear whether he was planning more violent attacks [....]
