An Anchorage couple stands accused of defrauding a local medical practice of more than half a million dollars, during more than 20 years in which the wife served as its bookkeeper.

Jill Diane Applebury and Darin Wade Applebury, both 52, are named in a 39-count indictment on counts ranging from bank and wire fraud to aggravated identity theft, Acting U.S. Attorney Bryan Schroder’s office said in a statement Thursday.

Chloe Martin, a spokeswoman for Schroder’s office, said both Appleburys were in custody Thursday and awaiting arraignment.

The alleged fraud, totaling at least $550,000, occurred over nearly a decade from 2004 until March 2013. Prosecutors said Jill Applebury had done bookkeeping work for the victimized business as an independent contractor since the mid-1990s.

Much of the case involved Applebury’s alleged use of a credit card for the business, which wasn’t named in the indictment, to buy items for herself and her family.

“The unauthorized charges to the medical practice’s business credit card included cell phone service for the Appleburys and members of their family, internet service for their residence, business licenses for businesses owned by Jill and Darin Applebury, automobile insurance for their personal vehicles, and other personal items,” prosecutors wrote.

In the indictment, prosecutors list some 27 counts as associated with unauthorized credit-card purchases ranging from the Apple Store to Best Buy and Costco, in amounts from $80 to $800. An inventory of some items the card was used for included a coffee maker for Darin Applebury’s mother, a vacuum cleaner for their daughter, a cellphone for Jill Applebury’s nephew and an alarm clock for her sister.

Jill Applebury also falsely claimed to be a full-time company employee at the medical practice, prosecutors said, in order to join a profit-sharing plan limited to employees. She allegedly received nearly $63,000 in unauthorized contributions in 2010 and 2011 as a result.

Darin Applebury is also accused of using almost $3,000 in funds from the business in transactions supporting his own business, Rapid Recovery Medical Service. Prosecutors said those transactions were conducted with his wife’s help.

Prosecutors also requested criminal forfeiture provisions in the case, under which the Appleburys would have to forfeit property or proceeds from any crimes in the indictment of which they are convicted.
