After completing law school, she joined the
Bergen County, New Jersey, prosecutor's office, where she handled some 50 cases as an assistant prosecutor. Her most notable case was the 1978 "Dr. X" murder trial of Mario Jascalevich, which she took on only four years after completing law school. The case dated back to series of suspicious deaths of surgical patients at
Riverdell Hospital in
Oradell, New Jersey in the mid-1960s. An initial investigation did not turn up any conclusive evidence of wrongdoing and the case lay dormant for a decade. In 1976,
M. A. Farber of
The New York Times wrote a six-month-long series of investigative articles which blamed a "Dr. X" for a series of murders at the hospital using
curare, a powerful muscle relaxant. The prosecutor's office reopened the case and an indictment was issued against Jascalevich, charging him with responsibility for five of the deaths after curare was found in bodies of patients that had been exhumed. The contentious case went to trial in February 1978, with Moses arguing that Jascalevich had played God, trying to make his colleagues look incompetent. Defense Attorney
Raymond A. Brown argued that Jascalevich was framed by incompetent colleagues and explained that the curare was used in canine experiments. Brown subpoenaed reporter Farber's notes, and Farber was jailed for 40 days for refusing to turn over the documents Brown had requested. The trial lasted eight months, then the longest criminal trial in New Jersey history; Jascalevich was acquitted of all charges. ==Judge==
