Lawyer identified as suspect in shooting of judge's son

The main suspect in the shooting of the 20-year-old son and the husband of a federal judge at their New Jersey home on Sunday was a lawyer and men's rights activist who was later found dead from an apparently self-inflicted gunshot wound.

Federal authorities are investigating whether Roy Den Hollander, 69, was the gunman who showed up dressed as a FedEx delivery driver at the home of US District Court Judge Esther Salas, 51, in North Brunswick, New Jersey, and killed her son and wounded her husband on Sunday afternoon.

The judge was in the basement at the time and was unharmed in the attack.

Police found Den Hollander's body in a car on Monday morning near the town of Liberty, New York, 160 kilometers northwest of Manhattan.

In 2015, Den Hollander, a Manhattan lawyer, brought a class-action lawsuit before Salas challenging the male-only US military draft that is still pending, according to the Daily Beast website. Oral arguments on a motion were scheduled for last month but then postponed due to "unforeseen circumstances", according to the case docket.

On his website, Den Hollander touted himself as an "anti-feminist lawyer", according to The New York Times. His lawsuit accused the US government's Selective Service System, the agency that maintains a database of those eligible for a military draft, of violating equal protection rights by requiring only men to register. Salas ruled that the lawsuit could proceed, and the case is ongoing.

Den Hollander drew public attention and derision more than a decade ago for his high-profile lawsuits over the constitutionality of New York nightclubs offering "Ladies' Night" drink discounts and universities offering women's studies courses.

Salas, the first Hispanic woman to serve as a federal judge in New Jersey, herself gained attention for presiding over high-profile cases. In 2014, she sentenced Teresa and Joe Giudice, two married stars of the television show The Real Housewives of New Jersey, to prison time over fraud charges.

Last week, she was assigned to oversee a class-action lawsuit filed against Deutsche Bank contending that the bank failed to flag "anti-money-laundering deficiencies" in transactions made by financier Jeffrey Epstein, who died last year in a federal jail in New York City while awaiting trial on sex-trafficking charges.

The judge's husband, criminal defense attorney Mark Anderl, 63, was shot multiple times and was hospitalized in stable condition on Monday, according to Carlos Salas, the judge's older brother. Their son, Daniel Anderl, a college freshman at Catholic University in Washington, died immediately from a gunshot to the heart.
