TACOMA, Wash. -

 A Washington woman accused of stealing more than $400,000 from her elderly uncle has been sentenced to more than four years in prison.

The News Tribune reports that 55-year-old Betsey Cammon of Anderson Island pleaded guilty Thursday in Pierce County Superior Court to multiple counts of first-degree theft.

Judge Elizabeth Martin called it "a breach of the most fundamental trust."

Court records show that in 1998, Cammon was granted power of attorney for her uncle, Bob Cammon. Nine years later, she was granted access to his bank accounts and in 2009 gained full access when her uncle was placed into a nursing home because of dementia. Prosecutors say she was supposed to use the money to pay his bills.

Bob Cammon has since died.
