A South Carolina mother who claimed her children drowned when her car careened into a river was charged with murder Tuesday after authorities said she confessed to suffocating the two toddlers and then faking the accident. 

Sheriff Larry Williams said Shaquan Duley, 29, told investigators she was distraught about her money troubles and unemployment and that she killed her children by putting her hand over their mouths after a dispute with her own mother. He says Duley then strapped the children into her car and drove it into a river Monday morning.

“This was a young lady that was in trouble, in trouble in more ways  than she realized,” Williams said. “She was in trouble and she didn’t know where to turn.”

Williams said the responsibilities of being a mother were simply too much for Duley, who didn’t show signs of remorse during an overnight interview with authorities.

“She truly felt, if I don’t have these toddlers, I can be free,” Williams said at a news conference.

Officials said they were unable to locate the children’s father, who did not live with the family. Duley has another child, a 5-year-old girl, who was now with the grandmother.

The state agency responsible for child welfare in South Carolina said it has had no involvement with Duley.

Devean C. Duley, 2, and 18-month-old Ja’van T. Duley were dead in their child seats by the time divers got to the car Monday near a rural boat landing on the North Edisto River in Orangeburg, about 35 miles south of Columbia, the state capital.

The Highway Patrol was notified around 6:15 a.m. that a woman needed help getting her children out of a car. Duley, who did not have a cell phone, had walked some distance down the country road by the boat landing and flagged down a passing motorist to call the Highway Patrol.

Duley was to be arraigned later Wednesday.
