Two Toronto women visiting Atlantic City were stabbed to death Monday in what police believe was a botched attempted robbery. The victims, aged 47 and 80, were alive when an ambulance arrived about 10 a.m., but died from their wounds in the afternoon at AtlantiCare Regional Medical Center’s City Campus. Antoinette E. Pelzer, 44, of Philadelphia, is charged with aggravated assault, and weapons and robbery offences. The accused woman’s mother has told some media her daughter suffered from schizophrenia and was likely off her medication.
