Michelle McMahan stole her patients' pain medications so she could take them herself. Diana Bjorneberg supported her drug habit by tampering with syringes and putting patients at risk for infection. Catherine Callaway replaced liquid anesthetics with saline, feeding her addiction while leaving patients to suffer. They are three of the 112 Minnesota nurses who since 2010 are licensed to practice despite having either stolen narcotics on the job, fraudulently obtained prescriptions, or practiced while impaired by drugs or alcohol, a Star Tribune examination of more than 1,000 Minnesota Board of Nursing disciplinary records has found.
