CONCORD, New Hampshire — A judge ruled Tuesday that the government had failed to find there was probable cause to charge a Warren woman with two of three drug charges while she worked as a nurse at a New Hampshire hospital.

Justice John Coughlin agreed that the New Hampshire Attorney General’s Office had presented enough evidence to send one drug possession charge against Kerry Bridges on to be considered by a grand jury, a court clerk confirmed on Wednesday.

Bridges’ attorney James Moir issued a statement on Tuesday, saying that a finding of probable cause requires an extremely low standard of proof and that the hearing was limited in scope and the accused had no access to any of the evidence against her.

The court complaints filed last month by the New Hampshire Attorney General’s Medicaid fraud control unit alleged that Bridges diverted drugs, including morphine, Fentanyl and Vicodin, from Concord Hospital. The state also claimed she administered narcotics without doctors’ orders, and could not account for all drugs.

The New Hampshire Board of Nursing issued an emergency order on May 22 that suspended Bridges’ privilege to practice nursing in New Hampshire until a hearing is held. The Maine Board of Nursing reprimanded Bridges in July 2014 following an investigation into possible diversion of drugs while she worked at Eastern Maine Medical Center in Bangor. Bridges, who had resigned as a registered nurse from EMMC in August 2012, denied diverting drugs but acknowledged her record keeping on administering narcotics was substandard.

Bridges had told the Maine board that she often got verbal orders from physicians to treat patients with pain medication while working in the emergency department.
