DES MOINES, Iowa (AP) — Federal prosecutors in Iowa have announced the indictments of six people suspected of having stolen various opioids from nursing homes where they had worked.

The indictments were announced in a news release Wednesday. Assistant U.S. Attorney Rachel Scherle says the cases are being prosecuted as part of the Department of Justice’s Elder Abuse Initiative. All are charged with acquiring a controlled substance by misrepresentation, fraud, deception, and subterfuge.

Those indicted are 36-year-old Arminda Cruickshank, of Osceola; 47-year-old Barbara Jean Tindall, of Keosauqua; 30-year-old Christine Renee Weilbrenner, of Ankeny; and 29-year-old Samantha Anne Mills and 32-year-old Alicia Danielle Swenson, both of Des Moines. They have all pleaded not guilty.

Prosecutors say 31-year-old Katie Christine Howard, of Des Moines, pleaded guilty to two counts on Feb. 11 and will be sentenced in July.
