An Acting New York State Supreme Court justice ruled that a second grand jury called to investigate so-called subway vigilante Bernard Goetz, who shot four youths last Decenber, could continue its deliberations. In a court hearing, Goetz's lawyers sought to have the grand jury dismissed. Justice Stephen G. Crane did not require Dist. Atty. Robert M. Morganthau to produce new evidence in open court, ruling that "the defense's claim lacks merit."
