LYNCHBURG, Va. (AP) -- -

Federal prosecutors say a former head teller at a Lynchburg credit union has pleaded guilty to stealing more than $1 million and contributing to the financial institution's collapse.

The U.S. attorney's office says 58-year-old Teresa Wieringo Humphries of Madison Heights pleaded guilty Tuesday to federal embezzlement charges. The government says Humphries stole several thousand dollars a month from the Lynrocten Credit Union between 2007 and 2013 and deposited the money into accounts belonging to her family members.

Prosecutors said the embezzled funds totaled more than $1 million and contributed to the credit union's failure last May. The collapse sparked a lawsuit by a Culpeper credit union seeking loan reimbursements.

Humphries could be sentenced to up to 30 years in prison and fined up to $1 million.
