COLUMBIA, S.C. -- A 30-year-old South Carolina mother has begun a 35-year prison sentence for killing her two young sons.

Records show Shaquan Duley (shah-KWAHN' DOO'-lee) was admitted Friday to a maximum-security women's prison in Columbia.

Divers pulled the bodies of 2-year-old Devean and 18-month-old Ja'van from the North Edisto River in August 2010.

Last month, Duley pleaded guilty to murder in the boys' deaths, admitting that she smothered them with her hands, then put their bodies in the river, staging a watery crash scene.

Duley said she killed the boys after a fight with her mother over her parenting skills.
