A woman was ordered to be held in jail after stabbing a dentist and attacking two other people on Wednesday inside a dental office on Magazine Street, New Orleans police say. Sharon Stewart, 55, will be imprisoned without bond as she awaits a Feb. 15 Gwen’s Law hearing to determine whether she poses a threat to the public at large. Slight and bespectacled, with an attentive manner and matronly short hair, Stewart’s appearance in magistrate court capped her alleged monthlong spree of threats, arson and attacks, including with a knife and hammer.
