A former nurse has been charged and has agreed to plead guilty in connection with the diversion of opioids from two Boston-area hospitals. Lisa Tarr, 33, of St. Petersburg, Fla., was charged and has agreed to plead guilty to four counts of unlawfully obtaining controlled substances by fraud, deception, and subterfuge. According to the charging documents, in August 2018, Tarr was a student nurse working at a Boston-area hospital. It is alleged that Tarr admitted to investigators at the hospital that she had stolen and self-injected fentanyl, a Schedule II controlled substance, from the hospital. In 2020, while working for another Boston-area hospital, Tarr stole an infusion bag containing fentanyl that was being used to treat a patient. On another occasion in 2020, while still working at the second hospital, Tarr stole multiple syringes of hydromorphone, a Schedule II controlled substance, from a locked drug cabinet.
