The investigation into allegations that a New Ulm doctor was stealing pain mediation from a vulnerable adult continues, and state documents show that Doctor David Miller has a history of substance abuse. He was allegedly caught by a surveillance camera taking pain pills from a patient’s bottle and replacing them with over-the-counter medication recently and was taken into custody. Miller is the head of the Brown County Detox Center in New Ulm, so he was taken to a similar facility in Albert Lea after being taken into custody to avoid a conflict of interest. He is scheduled to make his next appearance in court for the charges on March 19th. The Minnesota Board of Medical Practice says that Miller sought inpatient treatment for depression and alcohol-chemical dependency at a facility in Pennsylvania in 1993, and was admitted to the Riverside Medical Center Chemical Dependency Treatment Program in 1994. He had also been accused of writing prescriptions for himself using false names. His medical license had been restricted following those allegations, but was reinstated in 2000.
