Authorities say the gunman who they believe injured the husband of a U.S. district judge and killed her son in North Brunswick was an attorney, who was later found dead.
The FBI confirms New York attorney Roy Den Hollander is the primary suspect in Sunday's shooting.
He allegedly dressed up as a delivery driver, walked up to the North Brunswick home of Federal Judge Esther Salas and shot both Mark Anderl, her husband, and Daniel Anderl, her 20-year-old son who died.
Hollander managed to get away that night, but eventually led investigators to Sullivan County, New York, a two-hour drive from the crime scene. He was found dead in what officials reported as an "apparent self-inflicted gunshot wound."
Officials say Hollander held extremist beliefs and was extremely sexist, all of which he made public on his website.
He sued bars and night clubs for offering "ladies' nights," he sued Columbia University for its Women's Studies program and also sued the federal government, challenging the Violence Against Women Act, which he called the "Female Fraud Act."
In 2015, Hollander had a case heard by Salas and referred to her as "a lazy and incompetent Latina judge appointed by Obama." Investigators have not linked his hostility towards Salas as a motive.
Daniel Anderl, who had just celebrated his 20th birthday, wanted to be an attorney just like his father, who is now recovering Robert Wood Johnson University Hospital.
Salas is an accomplished Rutgers Univeristy alum. She is the first Hispanic woman to be appointed to the U.S. District Court in New Jersey and was nominated by President Barack Obama. She has a love for her family, a "dedicated family" as described by friends.
The investigation into the suspect is still ongoing by the FBI.
The family worships at Saint Augustine of Canterbury, where the young Anderl attended the elementary school.
The Diocese of Metuchen released a statement, which reads in pat: "Our hearts are heavy with the tragic loss of Dan Anderl, son of U.S. District Judge Esther Salas and the injury of his father, Mark Anderl." It went on to say: "We pray and mourn for the family and friends of the victims affected by this senseless tragedy."
