Gerson Fuentes, 27, appeared in a court in Columbus, Ohio, on Thursday where he was indicted on two counts of felony rape.
He was arrested on 12 July following the alleged rape of a child who travelled to Indiana for an abortion on 30 June.
Mr Fuentes, who has been held in a Columbus jail since his arrest, allegedly told a police officer that he raped the child on two occasions, although the timing and circumstances were unclear.
While he has not entered a plea, the indictment filed in the Franklin County Court of Common Pleas said the victim was aged nine when the alleged rapes happened. No further details were released.
A police officer told the court last week that Mr Fuentes admitted to raping the 10-year-old on two occasions following his arrest, which came after weeks of scrunity about the story.
