(CNN) — A mother in Kentucky has been accused of selling her baby for $2,000, police said.
Police contacted Maria Domingo-Perez, 31, after officials at Parker Bennett Curry Elementary School in Bowling Green, Kentucky, reported that a woman was giving away a child, police said.
Domingo-Perez initially gave officers "conflicting statements" but police said she later admitted to giving the baby to a man and a woman.
The couple, 37-year-old Catarina Jose Felipe and 45-year-old Jose Manuel Pascual, told detectives they had paid $2,000 for the baby, police said.
Authorities didn't discuss the gender or age of the baby.
The mother, Felipe and Pascual were arrested and charged with selling/purchasing a child for adoption on Tuesday, police and jail records show.
It was not immediately clear whether the suspects are represented by an attorney yet.
Police said the baby and Domingo-Perez's other four children are in protective custody.
