The judge’s son opened the door to the family’s North Brunswick home at about 5 p.m. Sunday and was immediately shot, sources said.

“He was shot through the heart,” Womack said. The son was a freshman at Catholic University.

The judge’s husband was then shot multiple times, according to sources.

A suspect “remains at-large,” a law enforcement official said.

Investigators have preliminary information that the shootings were carried out by someone dressed as a FedEx driver, according to multiple law enforcement sources.
