A former bank worker will spend the next four years in prison after embezzling funds.

66-year-old Mary Frances Dunn has been sentenced to 51 months in prison and to pay more than $800,000 in restitution, after being found guilty on one count of misapplication of bank funds by a bank employee.

Dunn appropriated $630,000 from a customer’s line of credit, while she was a loan assistant at Plains Capital Bank in 2003. She later embezzled another $157,000 from the same customer in 2008 after going to work for City Bank, as the person moved their account with Dunn.

Dunn must surrender to the Bureau of Prisons on or before June 24th, 2011.
