TUCSON, Ariz. -- A Tucson woman accused in the death of her infant daughter in January 2012 has pleaded guilty to manslaughter.
Pima County prosecutors say 22-year-old Olivia Paige Martinez entered her plea Thursday.
She's scheduled to be sentenced on Nov. 25.
Martinez originally was accused of first-degree murder, child abuse and abandonment/concealment of a dead body.
Martinez's lawyer says her client's boyfriend squeezed and shook the 11-week-old girl, causing grave internal injuries.
The couple fled Tucson with the dead infant, burying the body in the desert near Casa Grande.
Martinez and her boyfriend later fled to San Diego where they were arrested in April 2012.
The Arizona Daily Star says Martinez's boyfriend hung himself in his county jail cell three months later.
