The gunman suspected of killing the son and wounding the husband of a federal judge in New Jersey before taking his own life in New York’s Catskills has been identified as lawyer and men’s rights activist Roy Den Hollander, federal sources said. Hollander — whose website details “anti-feminist cases” and calls for clients to “help battle the infringement of Men’s Rights by the Feminists” — was found dead in Rockland County, NY on Monday, according to sources. Investigators believe Hollander shot himself hours after an attack on the North Brunswick, NJ, home of federal Judge Esther Salas.
