While Salas was in the basement of her home at the time, the gunman killed her 20-year-old son and injured her husband. Salas has presided over a number of high-profile cases, including the sentencing of a Newark gang leader, and was recently appointed to oversee a lawsuit against Deutsche Bank over alleged failure to properly screen the finances of Jeffrey Epstein.

The suspected shooter was an attorney who argued a case before Salas in 2015, ABC reported. It is not yet clear what the case concerned or what the specific motive of the gunman was.

The gunman arrived at Salas’s house dressed as a FedEx delivery person.

“We are aware of the media reports and are fully cooperating with investigating authorities,” a spokesman for FedEx told CNN.

New Brunswick mayor Francis “Mac” Womack told reporters on Sunday that he was not aware of any recent threats to Salas.

“As a judge, she had threats from time to time, but everyone is saying that recently there had not been any,” Womack said.

Salas’s son Daniel Anderl, 20, was killed by a gunshot wound to the heart. He was a student at Catholic University. Mark Anderl, 65 and Salas’s husband, was wounded and is in critical but stable condition.
