The suspect in the shooting of the son and husband of a federal judge in New Jersey was found dead from an apparent self-inflicted gunshot wound on Monday, ABC News and other media reported, citing law enforcement sources.

The suspect, a white male, had a case before the judge, Esther Salas, in 2015, ABC reported. He was found in his car in Sullivan County, New York, about two hours north of New York City.

Steven Nevel, a spokesman for the New York state police, confirmed an investigation of a death in the county but declined to provide further details.

The motive behind the killing remained unclear. Among her cases, Salas presided over the sentencing of members of the Grape Street Crips, a gang charged with selling drugs and other crimes in 2015, and federal fraud convictions of co-stars of “The Real Housewives of New Jersey” reality TV show.

Salas, 51, was nominated to her seat by President Barack Obama in 2010, becoming the first Hispanic woman to serve on the District Court of New Jersey. Salas could not be immediately reached for comment.

Her husband, Mark Anderl, 63, was an assistant prosecutor in Essex County before becoming a defense attorney. He and his partner, David Oakley, handle a variety of felonies, including homicide, sexual assault, and fraud cases, according to their website.

Daniel Anderl, the son, was shot as he came down the stairs of the home to help his father, who had opened the door to the gunman, according to some media reports.

“He ran down the stairs. Instead of running away he ran to help his father,” said family friend and neighbor Marion Costanza. Cortonza added that Daniel had wanted to follow in his parents’ footsteps and become a lawyer. “I want people to know what a good kid he was.”

Mark Anderl is now in stable condition after undergoing surgery at the hospital, North Brunswick Mayor Francis Womack told Reuters.
