The FBI has identified attorney Roy Den Hollander as the "primary subject" who shot and killed a federal judge's son and critically wounded her husband.

Den Hollander, now deceased, may have taken his own life in Sullivan County one day after terrorizing the federal judge's family in New Jersey. The FBI would not say if he killed himself, but do say he was found dead.

The body of the attorney was found just outside of the Beaverkill Camp Grounds on Ragin Road in Roscoe - a rural, vacation area with homes on spacious properties.

State police have not confirmed the identity of the body.

Officials are not currently saying if Salas or her husband were the targets in that attack. Both are high-profile figures.

Den Hollander had a gender-equity lawsuit, filed in 2015, that was being heard by Salas involving a young woman who wanted to register for the military draft. He also mentioned the judge in writings posted online, deriding her as a ladder climber who traded on her Hispanic heritage to get ahead.

A package addressed to Salas was found along with Den Hollander's body, the officials said.

In a screed Den Hollander posted online, he also wrote of posing as a FedEx delivery person to speak with a young girl, the same tactic the gunman apparently used at the door to the judge's family home.

Den Hollander was best known in years past for unsuccessful lawsuits challenging the constitutionality of "ladies night" promotions at bars and nightclubs. His litigation, and willingness to appear on television, earned him spots on The Colbert Report and MSNBC.

Salas' husband, Mark Anderl, is also an attorney, and Salas is the first Hispanic woman appointed to U.S. District Court in New Jersey. She was nominated by President Barack Obama and is well-known for presiding over high-profile cases, including one recent case related to Deutsche Bank involving Jeffrey Epstein.

News 12 has learned former Westchester District Attorney Janet DiFiore's name was found among his personal items law enforcement recovered. DiFiore is now the chief judge of the state of New York.
