The attorney identified as the suspect in a deadly shooting that took the life of a federal judge’s college-student son has been identified as a men’s right’s activist and self-described “anti-feminist.”

Citing two law enforcement sources, the Daily Beast reports that Roy Den Hollander is believed to be the person who arrived to Judge Esther Salas’ New Brunswick Township home on Sunday, dressed as a FedEx delivery driver.

The gunman reportedly shot Judge Salas’ son Daniel Alderl, a 20-year-old college student, through the heart when the son answered the door. The judge’s husband, 63-year-old Mark Alderl, was also shot when he went to the door, and remains in critical but stable condition after undergoing surgery.

As CrimeOnline previously reported, the suspect was later found dead in New York state, reportedly at a campground in the Catskills, of an apparent self-inflicted gunshot wound.

According to court filings obtained by the Daily Beast, Hollander has a case pending before Judge Salas involving a challenge to the male-only U.S. military draft.

A website that appears to belong to Hollander includes an apparent quote from the New York Times describing him as an “anti-feminist lawyer.”

“Now is the time for all good men to fight for their rights before they have no rights left,” a statement on the website reads in part.

This is a developing story. CrimeOnline will provide further updates when more information is available.
