There were fast-developing news reports late Sunday of a tragic shooting at the home of Judge Esther Salas, a longtime federal jurist in New Jersey. The shooting killed Salas' 20-year-old son and critically injured her husband, according to reports.

News reports began after 9 p.m. Sunday of a shooting at Salas' North Brunswick home by an unidentified gunman. The shooting didn't involve Salas, but killed her son, Daniel Anderl, and left her husband, attorney Mark Anderl, in critical condition as of early Monday morning, reports said.

The FBI as of early Monday morning were seeking information on one suspect.

Meanwhile, Gov. Phil Murphy and U.S. Sen Robert Menendez, D-New Jersey, who recommended Salas for district judgeship, issued statements late Sunday.

"I know Judge Salas and her husband well, and was proud to recommend her to President Obama for nomination to New Jersey's federal bench. My prayers are with Judge Salas and her family, and that those responsible for this horrendous act are swiftly apprehended and brought to justice," Menendez said.

Murphy said in his statement, "Judge Salas and her family are in our thoughts at this time as they cope with this senseless act. This tragedy is our latest reminder that gun violence remains a crisis in our country and that our work to make every community safer isn't done."

Salas, now 51, became a federal magistrate judge in 2006, and district judge in 2011. A Union City native, she was the first Hispanic magistrate judge in the state, and its first Hispanic woman district judge.

Following her June 2011 confirmation by the U.S. Senate, Salas said she was "deeply honored" and "humbled," adding that being the district's first Latina judge is a "tremendous responsibility."

"When I approached this job [as magistrate judge] … I approached it just proud to have reached that accomplishment," Salas told the Law Journal at the time.

Prior to her November 2006 swearing-in as magistrate judge, Salas spent nine years with the Federal Public Defender's Office, beginning in 1997. Before that she spent two years as an associate at Garces & Grabler in Trenton, handling mostly criminal cases. A graduate of Rutgers University and Rutgers Law School-Newark, she was admitted to the bar in 1994.
