A New York City men's rights attorney has been identified as the suspect in the Sunday evening attack on a federal judge's family. On Monday, the U.S. Attorney's Office identified Roy Den Hollander as the man who fatally shot Daniel Anderl, the 20-year-old son of Judge Esther Salas, and injured her husband, attorney Mark Anderl, at their North Brunswick Township home Sunday. Hollander, a self described antifeminist, had a case pending before Salas challenging the U.S. Military's male-only draft in 2015, according to the Daily Beast, NJ.com and the New York Times. On Sunday evening, he allegedly dressed as a FedEx driver when he knocked on the family's front door. When Daniel answered, Hollander opened fire — shooting Daniel first, then his father, ABC News reports. Salas was in the home's basement at the time of the shooting. Mark Anderl.
