A woman accused of helping her husband dump their teenage baby sitter in the woods is pleading guilty to desecration of a human body and other charges as part of a plea deal.

The Salt Lake Tribune reports (http://bit.ly/1s5WQv6) that 41-year-old Dea Millerberg agreed to the deal Wednesday in an Ogden court. She also pleaded guilty to obstruction of justice and obtaining a prescription illegally.

Prosecutors say Dea Millerberg and her husband, Eric Millerberg, had a drug-fueled, salacious sexual relationship with 16-year-old Alexis Rasmussen that led to her death from an overdose in 2011.

Eric Millerberg was found guilty by a jury in February of child-abuse homicide and sentenced to up to life in prison — the maximum amount allowed under the state's guidelines.

Dea Millerberg will be sentenced Aug. 21.
