An Arcadia woman pled guilty yesterday (Thursday) in the U.S. District Court for the Northern District of Iowa to stealing controlled substances from patients in a life care center where she was employed. Thirty-two-year-old Cassandra Lynne Vonnahme entered her plea to one count of acquiring a controlled substance by means of misrepresentation, fraud, deception, and subterfuge and one count of false statements relating to health care matters. Authorities say Vonnahme admitted during the plea hearing that she diverted controlled substances and falsified related documents between November and December 2020. Vonnahme was also convicted of burglary in Carroll County District Court in 2021 for impersonating a government official to steal controlled substances from a stranger’s home. A sentencing hearing is yet to be scheduled, pending the completion of a presentencing report. She faces a maximum penalty of up to nine years in prison, $250,000 in fines, and four years of supervised release.
