Shaquan Duley appears at an arraignment on August 18, 2010.
ORANGEBURG, S.C. (AP) -- A friend of the South Carolina mother charged with killing her children said she fought with the children's grandmother over who would give the youngest child a bath hours before they were slain.
Chea Phelps told The State of Columbia that Shaquan Duley called her crying on Aug. 15, saying she was leaving the home she shared with her mother because "she was fed up."
Authorities said hours later Duley took her 2-year-old and 18-month-old sons to an Orangeburg motel, suffocated them, then strapped their bodies into their car seats the next morning and let the vehicle roll into the North Edisto River.
Duley is charged with two counts of murder and is awaiting a bond hearing. Her attorney has said there is more to what happened than investigators have reported.
