The son of a federal judge died earlier this year saving his father and because of that heroism, others might be spared the same fate.

Authorities say that 20-year-old Dan Anderl was shot and killed by Roy Den Hollander, who was targeting Anderl’s mother, Judge Esther Salas.

“We must ensure, as Judge Salas said, that his death need not to be in vain,” says Sen. Bob Menendez.

According to the FBI, Hollander had a dossier on Salas and knew information such as where she lived and went to church. Two weeks after her son died, Salas implored those in power to do something to protect judges like her and their families.

A new bill named after Anderl would keep the personal information for federal judges private. It makes it illegal for data brokers to sell or use that information. No one can post it on the internet. U.S. Marshalls will have more resources to investigate threats.

“Unfortunately for my family, the threat was real,” Salas says.

Anderl died taking a bullet for his father, who survived three gunshot wounds of his own, along with multiple surgeries.

Anderl was a student at Catholic University and planned to study law. He was a graduate of Saint Joe’s in Metuchen. His old baseball team paid tribute to him over the summer during a tournament. They remembered him for his positive attitude and for being smarter than the coaches.

Anderl’s funeral was held over the weekend – two months after his death – to give his father enough time to recover.

Menendez recommended Judge Salas to then-President Barack Obama for her current position.

The bill does not include bodyguards for judges. It should be noted that most members of Congress do not have full-time protection either.
