U.S. District Court Judge Esther Salas told 60 Minutes in an interview that will air Sunday that authorities found a dossier on Sotomayor in a locker used by the assailant, Roy Den Hollander.
“They found another gun, a Glock, more ammunition,” Salas told the CBS News program. “But the most troubling thing they found was a manila folder with a workup on Justice Sonia Sotomayor.”
Den Hollander showed up in July at the New Jersey home of Salas, who had presided over one of his many lawsuits fighting what he perceived as feminist oppression.
Dressed as a deliveryman, he allegedly killed Salas’ 20-year-old son, Daniel Anderl, and wounded her husband, attorney Mark Anderl.
Authorities found Den Hollander dead from a self-inflicted gunshot the following day.
Since the attack, Salas has advocated for legislation to scrub personal information about judges from the internet.
“Who knows what could have happened? But we need to understand that judges are at risk,” Salas told 60 Minutes. “That we put ourselves in great danger every day for doing our jobs.”
A spokeswoman for the Supreme Court declined to comment on the report, noting that the court does not comment on security.
