A Puerto Rican man accused of impregnating his 11-year-old stepdaughter will stand trial for statutory rape, a judge has ruled.

The girl, now 14, gave birth about 18 months ago and DNA tests proved the man was the boy's father, said Sandra Figueroa, of the police's sex crimes division in the northern city of Arecibo.

She is now pregnant again and authorities suspect the stepfather is responsible, Figueroa said.

After hearing from five witnesses for the prosecution, Superior Court Judge Mirta Montes Villalobos determined on Tuesday that there was enough evidence for the case to go to trial, which is set for Feb. 20. The man was released without bail until then.

Figueroa said that defense attorney Jose Rubio Pitre had argued the girl could have been impregnated through artificial insemination.

After the hearing, Pitre told Noticentro 4 television that the prosecution did not provide a witness who said the girl was raped by the accused.

The girl's mother is accused of mistreatment of a minor and a hearing in her case is scheduled for next week.

Last year, another Puerto Rican man was charged with sexual assault after a paternity test established that he impregnated his 10-year-old stepdaughter. The girl's mother, who told police she twice caught her husband having sex with her daughter and forgave him, has been charged with two counts of intentional neglect or abuse by means of omission.
