The son of a US federal judge has been shot dead and her husband injured in an attack at their family home in New Jersey.
Investigators said the judge, Esther Salas, was unharmed.
According to BBC reports the attacker was dressed as a FedEx delivery driver and is still at large.
Sources quoted by US media said Judge Salas’s 20-year-old son Daniel Anderl – a student – opened the door at the family home in North Brunswick at about 17:00 on Sunday and was fatally shot.
The judge’s husband, Mark Anderl, 63, was then shot several times. He is in a critical but stable condition in hospital, the New Jersey Globe reported.
The motive for the attack is unclear. A local mayor and family friend said Judge Salas had received threats in the past.
Salas recently presided over an ongoing lawsuit brought by Deutsche Bank investors who claim the company made false and misleading statements about its anti-money laundering policies and failed to monitor “high-risk” customers including convicted sex offender Jeffrey Epstein.
The FBI says it is investigating and has appealed for information.
Salas’s highest-profile case in recent years was the financial fraud case involving husband-and-wife “Real Housewives of New Jersey” reality TV stars Teresa and Joe Giudice, whom Salas sentenced to prison for crimes including bankruptcy fraud and tax evasion.
