Lawyer Roy Den Hollander is a suspect in shooting at Judge Esther Salas’ home

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 had a case pending before Salas, challenging the military’s men-only draft, according to The Daily Beast, which first reported his involvement in the case. Investigators believe Salas’ husband was the intended target. The motive remains unclear.
