A former nursing home business office manager in Michigan has pleaded guilty to embezzling more than $460,000 from residents.

Tina Marie Binkley was accused of taking Boulevard Health Care residents’ money between May 2010 and April 2013. She was authorized to manage funds in the center’s general account, where day-to-day expenses were paid, and in the Resident Trust Fund account. The Michigan Attorney General’s office investigated bank records for the center and found Binkley transferred resident overpayments for room and board from the general account into the RTF account. She then had subordinate employees, who were not in on the scheme, make cash withdrawals and turn the money over to her.

There is no reason to believe anyone else had knowledge of her deceptive practices, according to a statement released by Michigan Attorney General Bill Schuette.

“BHC has cooperated with the Attorney General at every stage of this process and there is no indication of any lingering concerns with the facility’s books beyond the charges alleged against Binkley in this case,” the statement says.

Resident Trust Fund accounts have been a cause for concern in recent years following a USA Today investigation alleging that they often have poor oversight.

Sentencing for Binkley is scheduled for March 2. She could receive up to 20 years in prison and a fine of up to three times the amount embezzled. The center is located in Rochester Hills, roughly 30 miles north of Detroit.
